Column testing F&D R244

Before the cob, vibe, it is necessary to designate a de yaky channel. Don’t focus on the colors of the plugs - it’s better to run a test on the computer’s audio card, which has created sound fragments, to show if the column can be left, but not right.

Valentine 1908

Chinese company Fenda Science & Technology Corp. Group has already been on the market of acoustic systems for a long time and managed to establish itself only from a positive side. The company has been engaged in the production of acoustics, since 1993, and to this day, it has gained great popularity in more than 80 countries of the world.

Introduced in 2008, the F&D F-19 portable speaker system has immediately become a top seller in both the Chinese and European markets. Acoustics grafted transverse coristuvachiv, first for everything, with its design and, obviously, at a low price. A budget audio system from the F&D company is essentially a home cinema, but it can also be easily connected to a computer. Now, let's get to know the speaker system closer and look at what's out there.

Complete set

The F&D F-19 speaker set includes:

5 columns;

subwoofer;

Remote controller remote care;

speaker cable;

Interconnect cable 3.5 mm.

Starry look

We want to recognize those that the F&D F-19 is recognizing with its unique design among other models of the company. All 5 speakers of the viconan audio system are in a silvery color with chrome inserts on the sides, which reinforce the severity. The frontal and tiled speakers are ruffled on deyaky pedestals near the visible columns, the central column is ruffled apart from the others. The case of all 5 speakers is made of plastic, at the bottom of the frontal speakers there are wooden stands of black color, which are ideally connected with the main column. Dynamics of one smug, skin tightness of 18 W, which, as soon as I can, a little bit.

The main box with a subwoofer also has a bright, silvery color, on the upper part there are five chrome-plated control buttons. At the bottom of the box can also be a black stand, like front and rear speakers. On the back of the subwoofer case, there is a sound switch, audio input and output, as well as a radiator, which is used for the most hot elements.

Subwoofer design

The middle of the body is soundproof, made from synthetic winterizer. The entire acoustic system was chosen neatly and superficially; The front cover, as if I knew it, troch zbentezhila great amount of glue, which vikoristovuvavsya for fixing the elements. The intensity of the subwoofer becomes 60 W, you can see a dull sound. Obviously, for the budget version of Zide, but all the same, I would like it to sound better.

management

Controlling the acoustic system is one of the most important elements, even if you want to fix it yourself. Get out there like for help remote control, and for the help of five buttons, roztashovanih on the very body of the subwoofer. There are additional buttons on the remote control that allow you to adjust the acoustic system for the hearing of any kind of koristuvach.

You can adjust the subwoofer frequencies, adjust the “center” and “til”, and also turn on more than 3 speakers using an additional remote control. On the panel of accessories, roztashovaniya on the subwoofer case, there are only some functions, such as a loudness regulator, a switch, as well as a change of frequencies. Obviously, a clear minus in the management of the acoustic system is the presence of the RK-screen, even if unreasonably, adding a little coristuvach, or changing the sound, and also changing the sound to a tightness, having adjusted the subsidyuvach.

sounding

Good quality checks in a budget acoustic system, not at all Varto, but F&D
F-19 is showing itself kinder. If you plug it into a DVD-programmer, then it sounds amazing. Zavdyaki tilovymi columns hardly all sounds, sharudinnya that rose in the background is practical in any movie. The sound of the subwoofer may come out like a movie theater, but it is deaf and dull, but even more hoarsely. But if you connect the system to the computer and watch movies, then the sound quality is not clear, the speakers start to choke and become unacceptable to hearing.

Visnovok: pros and cons

Acoustic system F&D F-19, which is, obviously, a budget version, but you can help yourself with some kind of expensive model. A clear plus of the system is the price, which is already available to rich buyers, which means that you don’t especially need to watch, but simply enjoy looking at your favorite films and you can see that the stench is found at the cinema. The downside, however, is that the retailers did not transfer the RK screen, which is a perfect fit for such a futuristic design.

Tell friends

The wooden acoustics of the SVEN/F&D brand is active, in good faith to our modern readers we are in front of the latest price/quality ratios. As of 2001, the set of active 5.1-speakers SVEN/F&D IHOO 5.1 became available. It’s important not to wait, that with the appearance of the sale of this model, the idea was formed that, as far as possible, the acoustics have changed inexpensively. IHOO 5.1 - in front of two speakers, which sound like a good sound, the cases of some kind of broken wood, a well-designed subwoofer, balancing the power path, far away the QSound effect processor is stuck. And everything is for a reasonable price (about $200).

The deyakі can not wait and compare well in the conference, leading up to the fact that all the same radio used speakers are the best in the world (especially for the presence of a diploma of a radio engineer, an hour for a bugatory rework and a warehouse of spare parts for a complete replacement of all the insides). But those that IHOO 5.1 sound even more gidno and zatika for the belt are rich in 5.1 sets that are in the same price category, are left with a fact.

IHOO 5.1, obviously, is not ideal and may be short on both sound and functionality. In addition, the new one has a remote control remote control. Recently, the expensive 5.1-set SVEN 988 has appeared, de є a remote control without a remote control. At the same time, the price also increased, although all 5 speakers were absolutely the same, and the brightness of the front speakers was still sacrificed to the IHOO 5.1 set.

In this way, the version with the same speakers, like IHOO 5.1, looks quite logical, but also with a remote control and electronic regulation of all modes of operation. Itself about such a set and timetsya at the article. It is called F&D YF-IA. We are equally sounding of both sets, and marveling at what stinks exude one kind of one.

Starry look

The set is supplied in two packing boxes. The first of them has a ten-kilogram subwoofer, the other one has five speakers. The weight of both boxes is close to 23 kg.

Hot look to the F&D YF-IA set

Possibly, at sale it will be possible to make a set in a different color, we got a set of trimming of a silvery color with dark blue nets of fabric.

The YF-IA dial includes:

• subwoofer;
• n'five columns;
• remote control;
• kerіvnitstvo koristuvach;
• droti for connecting speakers;
• stereo RCA wired to stereo RCA.

Speakers

As we were already talking on the cob, all five columns, equal to IHOO, lost their invariables. Їх rozmіri to form (W × H × D):

• frontal - 168×220×300 mm;
• central - 400 × 150 × 140 mm;
• tilovі - 150×150×180 mm.

Although the bare numbers do not give you a full statement about the dimensions of the speakers, below in the photo you can see how the front and center speakers look on a 17 ”monitor LG Flatron.

Front and center set F&D YF-IA
order z 17" monitor and keyboard

Acoustic design of all five speakers is a circuit with a phase inverter. Open the phase inverter on back panel. Tovshchina of all walls to the center and front columns should be 15 mm, tilovyh - 10 mm. All vuzli that z'єdnannya vykonanі neatly and dosit hermetically. The middle of the body of the same soundproofing speaker is not to be guarded. The mid-frequency dynamic heads at the central speaker are the same, the intensity is 15 watts. The diameter of the paper diffusers is 10 cm, the flexible suspension of the windings is made of polypropylene. On the front speakers, there are three thinner wide-range speakers - 20 watts. The diameter of the paper diffusers becomes 11.5 cm, the flexible suspension here is already beating with the soft gumi. The tweeters that wink in the center of that front are absolutely the same. External diffusers, 25 mm in diameter, made of plastic and closed with a phase-shifting cap. The speakers are connected to the center and front speakers in parallel, and as a separate filter, an electric capacitor with a capacity of 2.2 mF is used.

View of the F&D YF-IA set with removed screens

Shards of the dynamic head may be magnetically screened, none of them should be put in place for an hour of work and close to the monitor, it was detected. The central and frontal columns have gum legs with a corrugated surface. For the rahunok of which the center is already engraved on the top of the monitor. Tilovі sateliti nіzhok do not wash, but are equipped with fastenings for installation on the wall.

Subwoofer

The subwoofer of the tested model is oversized by the dimensions of the subwoofer in IHOO 5.1, three times higher in height and twice as deep. The exact dimensions are 210×436×442 mm. For a short summary, we will show you a photo of the subwoofers of both models.

Subwoofer from the F&D YF-IA set (left hand)
versus subwoofer from IHOO 5.1 kit (right-handed)

Ale, it’s true to please such an expansion of the subwoofer in advance. The middle subwoofer is horizontally divided into two cameras, which do not interlock with each other, approximately the same size. For molding low frequencies the YF-IA subwoofer has only a top chamber. From one side - obsyag under the formation of low frequencies is less, from the other side - in the middle of nothing to derenchit and resonate.

At the lower part of the subwoofer case, a subwoofer board is ripped to fit the large toroidal transformer.

Electronic filling subwoofer F&D YF-IA

As you can see from the photograph, there are a large number of high-capacity capacitors near the life filter on the board, which will protect the background of the life-changing stream of life, which is to blame for the set.

The acoustic design of the subwoofer is a circuit with a phase inverter. The thickness of all walls of the subwoofer should be 18 mm. The opening of the phase inverter is shown on the front panel. The diffuser of the low-frequency head is led to the rear panel and navanted by an acoustic screen, while the woofer itself theoretically works in a larger frequency range, lower with a resonant chamber, and the CCD decreases in the region of the lowest frequencies. The low-frequency driver has a power of 50 W and an impedance of 6 ohms. Gnuchkiy podvіs vykonany z gumi, and the diameter of the diffuser becomes 16 cm.

The subwoofer itself is installed on a two-centimeter-high chotyri, vykonan from the slotted gum.

On the front panel, there are such buttons:

• power- Switch the system to power saving mode (stand by);
• Vol.up/vol.down- Zdiysnyuє regulation of density;
• mode- Switching modes of the robotic system (AC3, Stereo, Surround);
• Input- Switching modes of switching (DVD, CD/VCD, Tape, TV);
• S.Bass- add up to five channels of low frequency;
• Mute- No explanation required.

F&D YF-IA subwoofer panel

The intensity value is measured in dB. The found value is -79 dB, the best value is 0 dB. Adjustment of volume for the front, tail, center and subwoofer can only be done from the remote control. Also, the presence of a trismog equalizer (Treble, Middle, Bass) showed up, the regulation of which is also possible only from the remote control. The S.Bass button, obviously, is responsible for adding a low frequency to the sound, but the loudness at the speaker adds to the mids and s, which greatly dampens the sound. We would not recommend koristuvatisya with this lotion.

On the back panel are:

• Chotiri roses (RCA) for connection to stereo jacks;
• input (RCA) for six-channel connection;
• mechanical clamps for connecting speakers;
• vimikach life;
• zapobіzhnik.

Remote control for beeping in the "super-slim" style. Vin maє rectangular shape and six-millimeter tovshchina. Zhivlennya zdіysnyuєtsya in the form of one great three-volt "pills".

Remote control for F&D YF-IA

The weight of the remote control is too small and, as can be seen from the photograph, it is handy for the victorian. From the remote control, all adjustments are available, as can be from the front panel of the subwoofer. And two buttons SPK-і EQ Cool- nothing else, like adjusting the density of the channels and the equalizer.

Subsidiary part

There are two types of microcircuits in the subsilience tract of vikoristov. Five microcircuits TDA2030A and two microcircuits LM1875T All these microcircuits are smeared with thermal paste and pressed to the radiator with a metal bar (as we had a chance to take for demonstration the marking of microcircuits).

Microchips of the subsilience tract to the F&D YF-IA kit

Let's marvel at the fallowness of the sweat, taken from the specifics.

Graph of the THD deposition according to the tightness of the microcircuit TDA2030A

The TDA2030A microcircuit in the substationary path serves as a signal booster for five channels. Vaughn often sounds in active acoustics and has proven herself to be high indicators of tightness with a low value of dampness.

Vymiryavshi naprugu on vіdpovіdnih vіsnovіkі microchip, we took away the value of ±18 V. It's not to say about those that can be viewed without correcting the value of the axis of tension.

Zhivlennya zdіysnyuєtsya in the form of one great toroidal transformer, in the distance, in the form of subsidiaries pay for a sufficient amount.

Graph of the THD deposition according to the intensity of the microcircuit LM1875T

Two LM1875T chips serve to amplify the signal to the subwoofer. Vrakhovuchi those that the scheme of strengthening the brukivka, with a low THD value of the tension of the microcircuits, to stick with a large margin.

Porіvnyuyuchi subsilience parts of YF-IA and IHOO 5.1, it should be noted that the brands of microcircuits, which are victorious in the subsilience path, have not changed at all. For shaping 5.1-sound when stereo-jacks are connected to sound, as before, the analog effect processor QS7785 is used as QSound. Wikoristannya QS7785 can be characterized as an even farther away solution. For the clarity of the sound of it, one best solution for today's day.

Subjective listening

During the auditory test, the musical signal was introduced by WaveTerminal 2496 and Live! 5.1. The first victorious is used as a reference, and the other is called for six-channel and wide breadth. Needless to say, although on rich sets of multimedia acoustics the difference in the sound of cards is practically imperceptible, then on the YF-IA it looked good. In this way, before dialing, you can connect to a high-yielding signal.

The sound of the set can be characterized as kind. You can speak boldly about the good balance of the set. Trapleyaetsya, when vikoristannі set of acoustics with small plastic speakers and a great subwoofer, scho bumkaє, vіdchutno distinctly different sound of speakers and sub. Immediately, the subwoofer does not play well, but the sound is added to the sound of the lower register, angry from the sound of other speakers, not accentuating your own respect. The sound of a subwoofer has no additive resonances.

Ignore the less mindless movement of short, quiet rales (possibly, a defect in the test specimen).

The optimal expansion of the subwoofer will be the same, if the phase inverter is direct directly to the listener. In this way, the sound of the subwoofer becomes more pronounced and more pronounced, so it is easy to feel and you can accurately determine the height of the notes that are found in the bass parts. Obviously, when voicing vibes and gurkota in films and games, they do not play a great role.

I would like to emphasize the calm and noisy nature of the sound of the speakers. Navit for a trivial listening to music, there is no languor, what to do with acoustic sets. The timbre of the sound does not change on high pitches. The frontal speakers, perebuvayuchi one type of one on a stand 1.5 meters, create a stereo panorama. If you destroy them closer (it is possible, if you happen to be able to break through the table in such a way), the evenness of the sound field will deteriorate. Ale tse zovsіm does not mean that at the same time the quality of the sound is getting worse. Just for comfortable listening to music in stereo mode, it’s better not to turn the speakers too close one to one.

Maybe, the single minus of the speakers will be the marriage of the visionary high frequencies and the small cheekiness at the upper part of the mid frequencies. When in YF-IA, the equalizer does not radically change anything, and when trying to regulate, it only adds to the sound of creation.

And now, sing-songly, naytsіkavіshe ta hvilyuyuche for all readers and vlasniks IHOO 5.1 - full bet! The equalization of the sound of both sets was carried out according to the following scheme: the same test compositions were listened to on two computers, with alternating sound muting (with pre-regulation of equal volume). For precise alignment, the music signal was taken from professional cards with AKM AK4524 codecs (WaveTerminal 2496 and Hoontech DSP24 Value).

Results like this. As it happened, the sound of the speakers themselves did not change. Vlasne, and take it, there were signs: subsilience microcircuits - however, cases and dynamic heads - tezh.

And the axis of the sound of the subwoofers is the deuce of power. First, the IHOO 5.1 subwoofer has thickness with equal positions of the regulators rich, lower for YF-IA. The price is due to different schemes of acoustic design: a dynamic head and a phase inverter in YF-IA and a resonant chamber in IHOO 5.1 are installed. And as you can see, the resonant chamber can have a richer CCD, although it comes in latitude. frequency range and linearity of frequency response to other decisions.

As for the timbre of the sound, in our opinion, the sub IHOO 5.1 plays a little softer and more loudly sounds the lowest register, wanting not to blame too much great equalness - they blame the creation. Another important point: the sound of the IHOO 5.1 subwoofer is less than pleasant to the ears.

P_dvedemo p_dbag according to the test the sound of subwoofers For a small reason, we give the subjective advantage of the IHOO 5.1 subwoofer. The YF-IA subwoofer is ugly, but sometimes it deceives the eye through its promising large dimensions. Prote, the arrogant vіdmіnnostі negaraznі znachnі.

I would like to add one plus to the list of YF-IA achievements. When the set is turned on in the speakers and the subwoofer, there is no characteristic clatter in the transitional processes, which are heard in the blocks of life and subwoofers. On the right, if the set switches from stand by mode to working mode, the relay turns on the speakers. Those same vydbuvaєsya і at viknennі. Tim himself goes to try to get rid of all these unacceptable clatters and crackles, which IHOO 5.1.

However, this particular instance had a small problem: on the cob of the robot and the pivkhvilini from the subwoofer, there were some inconspicuous noises and wheezing.

Vimiryuvannya frequency response

The vimiryuvannya was carried out according to a single method program.

Frequency response of the front speaker IHOO 5.1 for a pair of speakers F&D YF-IA

A failure in the region of 2-5 kHz is bad, but not fatal. Adopt in the sound there are no strong timbre creations, it is less easy to confuse. Then є dosit even (± 3 dB) the middle and the top. Vidminnosti between the frequency response speakers - practically none. By ear, the difference also lies on the borderline.

Frequency response subwoofer IHOO 5.1

F&D YF-IA subwoofer frequency response

Behind the results, F&D YF-IA leads the way with subwoofers, showing a larger frequency range, which is confirmed. However, by ear, the IHOO 5.1 subwoofer sounded like a trifle to us, which is cleaner with more power. There is no such thing as any supernaturalness here. It's just that the frequency response is not the only and sufficient criterion, for which you can judge more about the clarity of the sound of acoustics. In addition, music has few frequencies like 20 to 50 Hz. This range is more relevant for voicing vibes in DVD-movies, but not so important is the timbre zabarvlennya and the number of creations. There is a smut, gazing at the armchair, it kicked. :)

Visnovok

Set of active 5.1-acoustics F&D YF-IA - ideal solution like an inexpensive home cinema based on a PC, with a DVD drive and a 6-channel sound card (or an inexpensive DVD player with a built-in decoder). YF-IA is a complete version of the popular favorite - the IHOO 5.1 set. Prote vlasniki of the rest can not be embarrassed. There were no special changes in the sound, the sound of the sound was increased for everything - the remote control of the recreation center, the electronic regulation of the modes, the sound of clattering when turned on / off.

If you talk about the sound, then the type that is being tested can easily and successfully cope with various musical compositions. In the order of dance and pop music, jazz is inauspiciously created and created, which is celebrated by a symphony orchestra. For igor - it is also a miracle solution. The stock of volume is too much to play, to sound not only a computer little piece, but also the whole room.

Obov'yazkovo varto to say that everything is known equal, and the skin price is worth its price. Vrahovyuchi large number of different inexpensive multimedia 5.1-kits in other virobniki (and choose why), F&D YF-IA tsіkavy us ahead of coristuvacha, yakі joking sound solution, optimal for the criterion of price / quality.

Pros:

• comment: IHOO got a remote control!
• wooden double wide range frontal columns;
• large central column of classic design;
• great wooden subwoofer;
• more garne sounding;
• effect-processor like QSound for listening to stereo sound on all six speakers;
• clatter when turned on
• ochіkuёtsya reasonable varіst (about $300).

Cons:

• tilovі columns pozbavlenі tweeters;
• it is possible, the set of cords for connection to the computer;
• inconspicuous noise and wheezing at the robotic subwoofer in a particular instance.

It so happened that decorative acoustics rarely become the subject of much respect in test laboratories of various computer sciences. Tse zumovleno odrazu kіlkom factors. In the first place, such systems are cheap, so the stench may be low in typical nedolіkіv, as it is necessary to look at the low price itself. In a different way technical solution similar columns in most of the vipadkivs do not become of particular interest. However, if you dig a little more, it becomes clear that for the number of sales the system itself is the leader - inexpensive, beautiful and compact. Therefore, today we would like to frequently correct the situation by protesting three budgetary sets of class 2.1.

F&D R313: tested classic

You can’t talk about a set of delivery of such systems, because in most cases it’s absolutely identical: two satellites, a subwoofer, a signal cable, instructions. Trifonika R313 is not to blame for this plan. Later, having opened the box, we were urged to complete the cicava system, broken down by all the classical canons. No designer frills and glamor, then do not forget all the basic rules and garna yakist preparation.

Satellites in small MDF cases in the shape of a rectangular parallelepiped. For added elegance, the edges of the front panel are rounded off. At the center of the expansions there is a wide-range speaker with a paper diffuser and a soft polymer suspension. Varto indicates that the quality of preparation in this case is even higher than the temple and in the case of more similar F&D R313 satellite systems, it is likely to be judged due to the low parameters. First, the stench is decorated not with a splendid black color, but with PVC material imitating the structure of natural wood. In another way, the meshes from the acoustic fabric are smashed by the wind. Tse allows you to vicorate columns with and without grills. The fact, it must be said, is more than reasonable for a budget decision. To install speakers on a horizontal surface of the transmission, there are chotiru gum feet, and the rods are fixed stationary. The annual roses were not transferred, the switches of switching with the support were realized with the help of spring clamps.

The subwoofer beats the same style. Significantly less, that the imitation of natural material is crushed even more successfully, that far away one can really think that the sub-splintering from the array of wood. On the front panel, there is a small decorative overlay made of black plastic. Here you can use three main regulators, a light diode and an external opening to the phase inverter port.

The acoustics control is thought out even more beautifully, but in the order of the volume control and the treble control there is a knob for changing the volume of the subwoofer. It is important, the shards of the skin of the ear can restore the frequency balance, which you have been honored with.

Zastosovane acoustically designed - bandpass of the fourth order. Such a scheme is characterized by some specific minuses, however, it is not allowed to take a decent sound pressure, which is better and more important in the analyzed price range. Connecting the system is even easier. As we have already reached the point, the satellites are connected to the spring terminals, and the computer signal is fed to the main RCA stereo input.

The installation of electronics can be called nedbalim, but there are no screaming nedolіkіv. Three microcircuits TDA2030A, tobto one per channel. For life, a transformer with a voltage of 31 VA is used.

In practice

The characteristics of this system do not call out any particular narcissists, but they cannot boast of their correctness. The subwoofer operates at 45 Hz, which is equipped with low acoustic design. At a frequency of 60 Hz, a clear peak is seen. A small failure is in store for the weather from the satellites. At high frequencies, the microphone fixes the sharpness of the day, to go over a steep blockage. Mayuchi such a frequency response, speakers gratimute far from the original, cold, but bright.

The sound of acoustics is rebuyed to an advanced level, especially for improved prices. Satellites are playing brightly and vividly. Timbral balance shifts to cold sounds. Regardless of the variety of wide-range speakers, the marriage of high frequencies is not indicated. Bass, as seen by the subwoofer, is clear and deep. At low and medium density, everyday artifacts do not appear. If you turn the regulator a little farther than the middle, then non-linear creations and streams of noise are indicated. The picture for the public sector can be finished with a standard one. Proteo hot yakіsny rіven can be assessed as good.

K-tri (Vigoole) E3120: contrast music

This set is sold in a small box with a standard delivery set: up to the new crim of the speakers themselves and instructions, it is only necessary to include a cable for connecting to the exit sound card computer.

The soundness of the triphonics can be characterized in one word - it is contrasting. From one side, we have a lot of classic cases and technical solutions, the prote over the design was clearly corrected for good. The black color of the cases is miraculously diluted with white plastic inserts. Satellites are absolutely amazing. The stench is made in a standard form, made from MDF and decorated with black PVC. On the front panels there are indistinct linings made of acoustic fabric, on the sides there are some sort of embroidered effect white smog, and on the bottom there is a company logo. Under the grids, one wide-range speaker with a perforated surface and a thick pad can be displayed. The magnetic system is screened on the outside, and on the metal there is a clear Vigoole stamp.

Paired with satellites, the subwoofer looks more efficient. The front panel is made of plastic, and the whole body is made of wood. The design is approximately the same: the main part is black, on the sides there is white smug. At the center of the front panel, three regulators and a bright blue light can be turned on. The largest knob serves to change the volume, and two small knobs adjust the balance of high frequencies and the volume of the low-frequency channel. All the regulators are illuminated by a blue light.

Like the F&D R313, it was designed to sound slightly acoustically designed with a dark-skinned resonator. A small loudspeaker is installed in the middle of the body on the partition, so that it adds volume.

The phase inverter port from one chamber is shown on the rear panel. On the slopes of the bachim there is an expansion, calling out to change the blame for the noise of the stream.

The back panel is classic. The metal insert serves as a fastening element for the main rosettes, and as a cooling radiator for microcircuits. All electronics are mounted on one board, as if folding to the temple. There are three microcircuits TDA2030A for the implementation of the vicorist. Zhivlennya zdіysnyuєtsya vіd step-down transformer z potuzhnіstyu secondary windings 24 VA. Therefore, the pressure formula 2x10 + 16 W looks like a little too much.

In practice

In this case, the subwoofer works at 50 Hz, which is good. Yoga energy is clearly naked at a frequency of 100 Hz. From one side in the other side there is nothing good, but from the other side, such a frequency response for acoustic design in the budget class is remembered. Inexpensive bandpasi oriented to high density, and the presence of wanting to keep the minimum brightness quiet. Frequency response may be uneven about ±5 dB for all smoothies. On the whole, it’s all good, but it’s not important to remember that the middle is badly hurt. Tse spriyatime timbre balance creation. Although, rightly seeming, the picture for the current $ 40 seems to be beautiful.

The defeat of the sound of miracles. First, varto means tightness. Irrespective of those that in the F&D R313 are modest figures, in practice the E3120 is louder, but it definitely shows a higher sound pressure without obvious non-linear effects. Satellites make yaskra barvisty sound. The stench miraculously embellishes the external signal, but it’s hard to call it short. Shvidshe tse specificity of work and a specific set. The subwoofer is loud and tight. Yogo sounding more slick and less shy to bubonic.

Edifier X400: grown-up sound with a harmonic look

The X400 model can rightfully be called the largest among today's trinity. Tse can be easily explained from the point of view of the price. See for yourself, the R313 costs close to $35, the E3120 is $40, and the X400 is $55. While Edifier and K-three (Vigoole) can still be matched, F&D is noticeably cheaper.

At the box you can find the speakers themselves, the signal cable and the traditional Edifier set of other products - instructions, warranty card, product catalog.

The soundness of the trifonika is pleasant, but the quality of the vikonanniya is simply miraculous. Satellites are prepared in (small) wooden cases, decorated with vinyl plaid and natural material. Cover not just maє similar babies, but repeat the structure of the fibers of the array. A speaker with a paper diffuser and a pilose-like cap at the sight of a cooler is located in the very center. For zamovchuvannyam vіn closing with a mesh of acoustic fabric. Vaughn has a pretty, cunning shape, and is not broken up by looking like a simple rectangle.

Before speech, X400 is the only set of three, which may not only be a gum base for installation on a table, but also a special opening for hanging on a wall. At the moment, you can be important, that is really a good plus.

Subwoofer vikonany yak cube. The dynamics of fastenings on the front panel and closing with a grid of acoustic fabrics. Well, I know, the X400 is a single system of three, de vikoristano with a more acoustic design - a bass reflex. Explain tse dosit simply. In this type of dynamics, the speaker obviously has more significant characteristics, that brewer did not have a chance to win different prizes for the high sonic vise. Natomist bass will be correct.

The main roses are concentrated not on the rear panel, but on a small plastic insert on the right end, which allows you to place the subwoofer in the right place at different times to the wall. The signal is sent to a 3.5 mm butt plug, so the signal cable may have an invariant configuration: there is a mini-jack on the skin terminal. Satellites arrive until the end of the implementation for the help of two RCA. Here you can also use two controls to change the loudness and loudness of the subwoofer.

The middle acoustics are broken even more. The installation of the electronic board is simply miraculous. The electronics itself is also great. Pіdsilyuvach, instigations on three UTC2030 microcircuits, live in a transformer with the intensity of the secondary windings 30 VA with two capacitors of 3300 microfarads each at the filter. Please note that with the actual parameters, the intensity of the satellites is declared at 6 W, and the subwoofer - 12 W. In times, the numbers are honest, and they don’t sum up.

In practice

Otzhe, look at the frequency response. The subwoofer is used in smoothies 50-200 Hz. The unevenness of the characteristics is not high, the prote at a frequency of 60 Hz is still clearly visible peak. The weather from the satellites was miraculous. The satellites themselves work even better, at a high frequency you can see a pidyom, which makes the sound sound brighter.

Subjective damage in the form of sounding with a high pitched sound is positive. The subwoofer demonstrates the performance of the robot and, in paired with the already reviewed sets, bass the most correctly. Yogo sounding is reminiscent of crispness and commanding detail of low frequencies. Before the speech, the latest peak of the great negative is not to be brought, at any time, to the test recipient. The sound of satellites does not call out claims. The stench roar loudly, which is especially important in detail.

I would like to guess that the Edifier X400 is the youngest of the line of gaming acoustics, it also includes the X500 and X600 models.

At the result, the results of our today's test proved to be worthy of a pass. Behind the yakіsnimi pokazynnya the acoustics were roared out of the declared price. Found є column F&D R313, stench cost less than $35. When you dial it, you can have a classic sound and ensure the normal quality of the sound. Rumor qiu system all the same, it’s more beautiful at low and medium volumes.

Acoustics K-three, and the same trade mark is used for official sales of Vigoole speakers in our country, the E3120 looks more modern and memorable, that is a good example for a room with a bright design in hi-tech style. At a price of about $40, the E3120 is seen to produce a better sound, as for a small price difference it is better to bypass the R313.

The Edifier X400 is another acoustics, but the stones are already a transitional option between door-mounted decorative and mature systems. The dialing of the sounds is even more pronounced, and the sound is the most correct and detailed. However, the price of 400 things is $55.
