How to choose a speaker system
1.How much money is spend on speakers?
The type and quality of speakers depends what effect you get from your home theater as a whole. Too simple cheap acoustics can lead to the fact that all of your expenses for a quality home theater would not be justified. The optimum amount is allocated for the purchase of the columns will be equal to approximately 50% of the total theater experience. Some experts believe that this figure should increase to 70, but in our opinion, it is already too much.
Two. The more active speakers are different from the passive and what is best to choose?
The difference between active and passive loudspeakers is that the former have a built-in amplifier (usually it is in the subwoofer), while the latter do not have it, so for the reproduction of sound through speakers requires a separate amplifier. In the active acoustic systems is less intermodulation distortion, as each amplifier operates in its "narrow" band and separate amplifiers for each band do not interact with each other. Active speakers have a better dynamic range, that is to create the same level of maximum sound pressure will need an amplifier with less power. As a result, two-way active system with separate LF and HF power amplifiers 60 and 30 watts will be louder and more dynamic than the passive, is included together with a capacity of 175 amp Tues
In passive acoustic systems, several problems arise due to the presence between the amplifier and speaker separation filters. If the amplifier and speakers transmit pulse signals are not the best way, the listener will never get rich natural sound, can not feel its volume. But, nevertheless, the main criterion when selecting the type of columns is often the presence or absence of a separate amplifier.
Three. What are the best speakers - bookshelf or floor?
It depends on how, in what price range is a choice. If you are not willing to spend more than $ 1,000, buy shelf monitors, since when there is resonance of the body floor, plus a rather large error tones. Shelving options will give a more accurate sound, even for complete comfort you will attend to the problem of acquiring a good rack. More expensive models offer you the acoustics and a wider choice if you enjoy large-scale rich sound for movies, buy outdoor speakers, but if you are music lovers who appreciate the nuances of musical performance - for you will be the best option for a couple of shelving.
4. Which stands for bookshelf speakers is preferable?
To set the bookshelf speakers are an excellent choice for wall brackets. They will avoid resonance, thereby ensuring the best sound. If you for some reason do not want or can not use a wall mount, floor models, choose frames, which can be filled ballast. This little trick will give your counters greater resistance.
Five. What a way to mount speakers to the stands to choose?
It is best to mount the acoustics to the posts with special spikes or metal cones. They provide the best isolation from the front speakers. But if you want a more secure fit, you must select two-sided sticky tape, securely locking your acoustics. Thus, you will not worry that children or pets accidentally overturned column.
6. How should arrange the speakers to get the best sound in your home theater?
Arrange in a circle - the most widely used option, it is - the best. In order to avoid resonances speakers should be placed not too close to the walls, and at a distance of about half a meter from them. Front speakers should be placed at ear level sitting audience, the rear - at about 130 cm from the floor. The subwoofer must be installed at the point in space, where it reaches the deepest bass (this is determined experimentally, by ear).
7. Should I use weights to clamp column and that it will?
The increase in mass of the column with separate cargo hold-down housing contributes to the suppression of resonances, providing a cleaner sound. Bruschi-clamps can be purchased at specialty stores, and can be ordered in a workshop on metal.
Eight. What is the warm acoustics and what is it for?
The sound in the new, just purchased speakers rather "hard", and comes back to normal only after a certain time of use. In order to quickly get a good result, use the "warm" speakers, which occurs in sound reproduction. Usually acoustic warm up for at least 100 hours at a low volume, for example, include before going to work and leave work for the day. Best "warming" is the use of broadband, "wavy" signal present at the special test drives: they make the acoustics of a uniformly developed all the speakers. A frequently used method of heating - front speakers deploy the parties to each other, so that between them there was almost no clearance, to include one column in the opposite, and to put music on high volume. As a rule, the difference is especially noticeable in the sound of more expensive models.
9. If then the speakers for some time been used, whether she needed an additional warming?
No, it is not necessary. Just turn on the music for 2-3 hours, after which you reach a good quality sound.
10. What is the resistance of the speaker is better to choose? Does that mean that the speakers with 8 ohm loads better than the equivalent of 4 ohms?
Decisive role in choosing an amplifier is used. Many vehicles with a load of 4 ohms work quite unstable, so the sound quality leaves much to be desired. In the manual for your amplifier should be pointed out, what spoprotivlenie columns for a most preferred. If the amplifier is linear to the load, it is enough for 4 ohm speakers - a number of vehicles gives them almost twice as much power than when using 8 ohm-GOVERNMENTAL counterparts.
11. Columns with which the lower cutoff frequency should be preferred to more fully play "bass"?
This can be solved only you, to listen to audio from multiple speakers. The lower frequency limit in this case is chosen purely individual. Most critical is the size and number of bass speakers.
Please note that specified in the instruction manual frequency does not always give the result of which the producers say.
12. What should be the upper frequency, the importance of expanding the frequency range of speakers from the top - from 20 kHz to 50-100 kHz?
Despite the fact that the human ear can not perceive frequencies above 20 kHz, high-resolution music formats often have an extended frequency range. The sound on these frequencies, it seems easier, "air", but can get the opposite effect - at frequencies from 20 kHz to 100 kHz, there is additional noise, interfering with perception. When choosing speakers with extended frequency range is better to rely on your taste, that is, listen to speakers and make sure you are satisfied with the sound.
13. What is the sensitivity of the speakers I need?
Sensitivity - is the sound pressure level sound system, measured in decibels. That is, the higher the sensitivity of the speaker, the louder the sound it is able to give. The higher sensitivity of the system, the less powerful amplifier is required to reproduce the desired sound level.
The numerical value of sensitivity, for example, 90 dB / W / m, mean that the speaker is able to create a sound pressure level of 90 dB at 1 m from the speaker when input power of 1W. The sensitivity of conventional AC ranges from 84 to 102 dB. Conventionally, the sensitivity of 84-88 dB can be called low, 89-92 dB - average 94-102 dB - high.
But remember that high sensitivity is often achieved by reducing the resistance of acoustics, that is, the complexity of the load for the amplifier is also increased.
14. How to choose an amplifier, if you already have speakers with a sensitivity of 92 dB, the resistance of 6 ohms and recommended power input of 50 to 150 watts?
An important factor when choosing an amplifier is the damping coefficient: the higher the value, the better it is desirable that it has not been below 80, the optimal value of - 200. It also plays an important role dynamic range. Power to the speakers, depending on your tastes and preferences, but in any case, be aware that the power of 200 watts is enough for any music, and audio in home theater.
As a rule, in the statement declared maximum power, which is in the home can not be obtained. There'd better pay attention to energopotreblenie amplifier and safely share that figure by 2. This will be the total power of all channels. Also keep in mind that the volume does not increase in direct proportion to an increase in amplifier power: 150-watt amplifier sounds just twice as loud than the 15 - watt. But the speaker with a sensitivity of 90 dB will sound 2 times louder than 80 dB sensitivity.
15. Should I use at home professional powered speakers?
Use a professional speaker can be at home, but compared to the traditional home audio acoustics, active reproduced by professional speakers, is perceived as a "few emotions". This is because the acoustics in the development of a primary emphasis on the neutrality of the sound when listening to music that may disappoint you. If you want to use these speakers for home theater, then they should be fine.
16. What is a subwoofer and is it worth it to use when playing music?
Subwoofer - a speaker designed specifically for playing the lowest frequencies that small speakers can not give. Subwoofers are divided into active and passive, but for home theater produce mostly active. When listening to multichannel music need necessarily a subwoofer, because it has a separate "bass" channel.
17. If I connect two subwoofers, will sound better than using one?
Yes. When the connection of two "bass" bass speaker orientation will be reduced and the overall quality of music will increase significantly. Connecting the subwoofer can be parallel or with a cable splitter.
18. Which is better to use cables to connect speakers?
Speaker cables - quite an important element of the whole system, so they do not save on costs. The optimal value of cable - 5% of the total system cost. For the switching of electronic components is better to use a cable of minimal length, as long cables more susceptible to interferences and signal distortion. When choosing speaker cables better guide section of the conductor: the bigger it is, the thicker the wire cable, the better the signal integrity is achieved, which is especially important in the transmission over long distances. It is well proven in the market cable brands such as ProfiGold, Supra, XLO, Kimber, AudioQuest, Nordost.
19. Is it possible to improve the sound quality has purchased speakers?
Yes. You can only replace the internal wiring for better and change the original bitumen filler for insulation - and is not independently, but with the help of an experienced specialist.
