For many readers the choice of a set 5. acoustics is a challenge. And it is not surprising, in fact in the market there are tens similar products. The information can be gathered from numerous sources — from clauses in specialized press, from sites of manufacturers in a network. However, at times there is only poor description and the list from practically identical to all models of characteristics. It is possible to esteem opinions of users in conferences, but not each of visitors possesses due qualification. Responses in forums frequently cause additional questions and doubts. To the user anything else does not remain, as most to choose suitable acoustics.
The material is calculated on the reader who is interested in a question of a choice active computer notebook sub 5.1-akustiki or wishes to be well informed about last achievements in this area. In the beginning of the review we offer a brief management on the given theme. Further there is a detailed testing five modern sets of multichannel acoustics most interesting, in our opinion.
(active, powered speakers) the columns having built in amplifier refer to as active acoustics. It is enough to connect of them to a source of a sound, to include a feed, and they will work. While (for example, polochny'm Hi-Fi to columns) the external amplifier which is on sale separately is necessary for passive columns.
Sets 5.1-akustiki represent ready complete sets from satellites and a subwoofer. The power unit and the amplifier are built usually in the case of a subwoofer. On a back part of a computer notebook sub subwoofer sockets of switching settle down. Frequently there are some stereoinputs and a multichannel analog input for connection of a computer or DVD-pleera with the built in decoder.
The greatest interest is represented with sets of acoustics of an average price category, $150-2 with wooden (MDF) cases of satellites and more or less qualitative dynamic heads (rubber podves srednechastotnika, dome fabric pisch'alka).
Cheaper sets have more likely decorative purpose and can be chosen on photos and specifications.
Whether there is an alternative to ready sets? Certainly, you can collect the complete set from separate so-called Hi-Fi components: multichannel AV-resiver, a set from columns, an active subwoofer. However prepare for increase in expenses at least up to $400.
Among users computer notebook sub there is an error about an opportunity of the organization of a high-grade cinema on a computer. There is a temptation to buy 5. set of tiny dimensions, having saved space, or by a principle - loudly it is not necessary, therefore greater columns are not necessary.
We hasten to dispell error. In practice the size diffuzora strongly influences quality of a sound. Small decorative kolonochki cannot provide high-grade sounding. Not going into details, there are the restrictions imposed by laws physicists.
The increase in dimensions of columns allows to realize polnochastotny'e acoustic systems. First, it is possible to put dynamic heads on the order of higher quality. Secondly, there is a place computer notebook sub for application separate dinamikov for VCH and SCH/NCH ranges. Thirdly, the volume of air weight inside of the case can be used for strengthening LF, at realization of acoustic registration fazoinvertornogo type.
Certainly, in itself dimensions of columns still do not guarantee quality. There are sets of inexpensive full-size acoustics which nearby send away on a level from decorative. But it more likely exception.
Summarizing all above told, we have selected the most interesting complete sets presented in the market at the moment of testing (Autumn of 2006). Models are topovy'mi in rulers 5.1-akustiki corresponding manufacturers.
Let's pass to participants of testing. We shall result the most essential characteristics, unlike enough useless nameplate data, soundings really computer notebook sub influencing quality.
We have not casually allocated with separate item a retail price. This parameter is considered at removal of a verdict about a parameter cena/kachestvo.
In testing real copies from retail shops have been taken by autumn of 2006. It is necessary to do the amendment that models of different years and different parties can differ on quality of accessories and on sounding.
That there were no superfluous questions on sequence of following, descriptions of sets follows in alphabetic order.
Sounding of satellites of set Genius SW-HF5. 50 has strongly pronounced okrashennost' in mid-frequency area. This lack is expressed in osch'utimom tembral'nom change of sounding of tools on these frequencies. Thus in sounding the effect of a compression which leads to fast fatigue of hearing is observed.
Shortages computer notebook sub of high frequencies in sounding a set it is not observed. However owing to a plenty of distortions to name VCH-diapazon qualitative it is impossible. All sounds of plateaus and perkussii are listened underlined, thus sounding very much does not have detail.
Subwoofer SW-HF5. 50 plays not bad. The subwoofer is of little use for musical application. Owing to application of acoustic registration of the resonant chamber for sounding a subwoofer it is characteristic guloobrazny'y character. Also in sounding the greased attack and inexact transfer of height of sounds of bass parties is observed.
For a soundtrack the subwoofer approaches to films more as the applied scheme allows to reach high EFFICIENCY, and the working range saba begins already from Hz.
Advantage Genius. At set Edifier shortage of high frequencies, strong okras on SCH.
Advantage Genius. computer notebook sub Genius has brighter sounding. At JetBalance shortage low, even stronger tembral'ny'y okras.
Clear advantage Microlab. Sounding Microlab more comfortable, is not present such okrasa and perekompresch'ennosti, as at Genius.
Clear advantage SVEN. Much more detailed, high-grade sounding at SVEN in all range.
Non-uniformity ACHH of face-to-face satellites: dB in a range 1 - 300 Hz
Level of distortions of face-to-face satellites: average, with prevalence in high-frequency area
Working range of frequencies of a subwoofer: - 1 Hz at non-uniformity dB
At satellites shortage of high frequencies at which addition by a regulator of a timbre distortions increase is felt. Nevertheless, it is possible to find the compromise and to improve sounding by raising VCH a little. In any case of detail does not suffice.
On the average the register are observed tembral'ny'e computer notebook sub changes. Sounding has no strongly pronounced painting that would by all means be shown in the form of strong distortions of timbres of tools, but at the same time the failure in the bottom range of frequencies that leads to dimness, inferiority of a sound is felt.
Owing to acoustic registration « the closed box », is not enough quantity of low frequencies. Potentially such konstruktiv gives chance of the best study of averages and to the best attack, but not in this case.
Subwoofer of a set - the best among presented to the given testing. Designers managed to realize active NCH-kolonku at a high level. In sounding there are no parasitic average frequencies, the bottom register is well worked, thus there is no the rumble inherent in resonant schemes.
Small advantage Edifier. Tembral'no is more authentic and better on detail.
Advantage Genius. At computer notebook sub set Edifier shortage of high frequencies, strong okras on SCH.
Clear advantage SVEN. Edifier concedes on a saturation on high and low, and on reliability of timbres on SCH.
Clear advantage Microlab. At set Edifier shortage of high frequencies, strong okras on SCH.
Non-uniformity ACHH of face-to-face satellites: dB in a range - 350 Hz
Working range of frequencies of a subwoofer: - 1 Hz at non-uniformity dB, port FI from Hz
The first, that draws attention at acquaintance to a set - a plenty of distortions on high frequencies. Sounding on average frequencies rather free, but at the same time timbres - are cut strongly up. It leads to deterioration of transfer in the most important range.
At all lacks, advantage of set Jetbalance in the open sounding. Rubber podves promotes it, leading to more comfortable computer notebook sub sounding.
The amplifier on satellites comparative weak, a subwoofer strongly dominates, so it should be cleaned on loudness. Harmonics of the maximum orders reach high-frequency area, leading parasitic prizvukam. From pluss - the sated sounding in low-frequency area.
Small advantage Edifier. Tembral'no is more authentic and better on detail.
Clear advantage Microlab. At JB shortage low, even stronger tembral'ny'y okras.
Advantage Genius. Genius has brighter sounding. At JetBalance shortage low, even stronger tembral'ny'y okras.
Clear advantage SVEN. Jetbalance essentially concedes on a saturation on high and to quality SCH.
Non-uniformity ACHH of face-to-face satellites: dB in a range - 220 Hz
Level of distortions of face-to-face satellites: average, high on edges of a range
Working range of frequencies of a subwoofer: - 1 Hz at non-uniformity dB, port FI from Hz
Owing to the small size diffuzora ( sm) sounding on average frequencies defective. There is computer notebook sub an effect zajatosti. It would be desirable more free, open sounding. Shortage of detail affects a stereopanorama.
In comparison with averages, high frequencies look more preferably and improve a general impression. Though lacks are available, on a level quite correspond to the given class of acoustics.
In comparison with referensny'm sounding, there are distortions of a timbre. But in comparison with Genius, JetBalance and Edifier timbres are more natural, sounding as a whole purer.
It is not enough low frequencies. It speaks in the small sizes diffuzora dynamics and low overall performance FI.
The subwoofer grasps SCH, therefore is obviously localized in space. Would not prevent a crossover with a greater steepness of recession. Attack normal. For reception of the balanced sounding it is recommended to reduce a level of loudness saba up to a minimum at connection to a stereo to inputs. At connection to 5.1-vhodam the computer notebook sub subwoofer plays more sbalansirovanno.
Clear advantage Microlab. At set Edifier shortage of high frequencies, strong okras on SCH.
Clear advantage Microlab. At JB shortage low, even stronger tembral'ny'y okras.
Clear advantage Microlab. Genius are too underlined perekompresch'enny'e SCH, tiring sounding.
Small advantage SVEN. At Microlab less than low frequencies, detail, less natural timbre there is less.
Non-uniformity ACHH of face-to-face satellites: dB in a range 1 - 400 Hz
Working range of frequencies of a subwoofer: - 3 Hz at non-uniformity dB, port FI from Hz
Among participants of testing, sounding SVEN HA-1410T, in our opinion, the most comprehensible. Quality of a sound is most approached to reference first of all computer notebook sub owing to dinamikov, which by a class above, than in products of other manufacturers. It is necessary to note maximal use of dimensions of columns. The size diffuzora practically coincides with width of the forward panel.
However it does not mean, that the given set has no lacks. At cost 5.1-nabora under $300, satellites all are still far from quality of modern active stereocolumns $ for pair. For this reason we consider, that the potential of a set on quality is realized not completely.
The main feature in comparison with competitors - free, bright sounding on the averages, not having expressed tembral'nogo okrasa. Good detail provides comfort of listening. High frequencies are worked better, than for competitors. The minus - non-uniformity gives a shade on VCH, and also kompressionnost' sounding in the given range.
FI satellites works insufficiently effectively - computer notebook sub since 1 Hz there is a strong blockage. On hearing it is expressed in insufficiently sated sounding in the bass register. Thus port FI is for some reason adjusted on Hz. On a plan of developers, possibly, LF the range is given a subwoofer.
However sounding of a subwoofer at all does not impress. Instead of "subwoofer" in the complete set goes «vufer», certain active NCH-kolonka, with a range from the top part of LF up to bottom SCH, approximately from up to 2 Hz. In our opinion, the given subwoofer mismatches on a level to satellites. Knowing opportunities of the given software producer to successful active subwoofers, we can ascertain, that in this set the subwoofer has turned out proval'ny'm. There is a sharp desire somehow to coordinate work of a set, for example, to adjust frequencies of a cut of a crossover, but such opportunities it is not computer notebook sub represented.
Clear advantage SVEN. Jetbalance essentially concedes on a saturation on high and to quality SCH.
Clear advantage SVEN. Edifier concedes on a saturation on high and low, and on reliability of timbres on SCH.
Clear advantage SVEN. Genius are too underlined perekompresch'enny'e SCH, shouting, tiring sounding.
Small advantage SVEN. At Microlab less than low frequencies, detail, less natural timbre there is less.
Non-uniformity ACHH of face-to-face satellites: dB in a range 1 - 400 Hz
Working range of frequencies of a subwoofer: - 2 Hz at non-uniformity dB
We consider, that any of multichannel sets does not realize potential on quality. Even at the low cost, quality of sounding of satellites does not come nearer to modern representatives of a stereo of acoustics.
Development of 5. sets aside qualities of sounding goes the turtle computer notebook sub rates. The face-to-face satellite of the best set does not hold out on quality up to stereocolumns SOLO- of the sample 5-letney prescription, not speaking about modern models.
Among the tested models we allocate Microlab H-5 and SVEN HA-1410T. Objectively sets the most successful. At the same time, it is necessary to consider and rather high cost - model SVEN surpasses, for example, product Genius at the price of almost in times.
In the given testing we do not award any participant. Microlab and SVEN at the high price have constructive defects. Though SVEN possesses the best sounding of satellites, the subwoofer mismatches this level, therefore HA-1410T the Leader of the Class does not receive. Microlab has no such problems with a subwoofer, however, considering greater investments in design and royal'ny'y a varnish, dynamics of satellites have remained computer notebook sub on the second plan.
cena/kachestvo inexpensive sets Genius and JetBalance do not receive the award for an outstanding parity owing to unsatisfactory sounding. Though the buyer saves the significant sum, in our opinion, such economy is not justified. Sets nearby send away from decorative acoustics for the smaller price.
The best subwoofer among all sets, but satellites are necessary for changing completely, since dinamikov and finishing the acoustic scheme and volume of the case. As a result the given set looks serednyachkom and also does not receive awards.
We finish testing for the major note, in hope to see from manufacturers really competitive products made without scandalous constructive lacks and without skews on quality aside of satellites or a subwoofer.
