1. First determine the daily operations of the speakers later; for music, movie or gaming.a. For music you should select a speaker with only 2 channels without a subwoofer with a reason to pursue detail and quality of hearing. 2 way speaker is the minimum recommendation. If it is possible to choose a 3 way all the lines can reproduce the sound spectrum as well (although multi media speaker 3 way is still scarce and expensive).
b. For Movie and gaming should choose at least 2.1 channel speakers (5.1 would be better but still not worth 7.1 in terms of price vs. performance).
2. Enclosure / Box speaker in determining the quality of sound produced (generally associated with poor tone quality) Choose the enclosure made from wood (MDF, HDF or Laminated wood) enclosure made of plastic rather than wood because it had a resonance damping effects are much better than plastic. If there is no other choice, enclosure made of plastic can still be improved its performance by adding a damper on the enclosure (generally rockwool or Glasswool). Also affect the choice of type of enclosure kualiatasnya anyway. The options include: Sealed, ported and bandpass type.
3. Quality cone also has a stake in reproduction "sound color". Multimedia speakers in the market generally only use paper presser and IMPP cone, but in fact there are many types of cone material so that there are also many "colors" the sound it produces.
4. Do not be provoked by a large watts it sure sounds good too, probably the closest are: the ability level of violence may be more loud sound but it still depends on the sensitivity of the speakers.
5. When the pursuit of sound quality, avoid the speaker with a built in amplifier as we find in most multimedia speakers. Level hum, wow and flutter of a built-in amplifiers tend to be larger than separately amp (even more so on the speaker with a wooden enclosure), because the ability of wood to reduce interference in quite bad.
6. Avoid buying a speaker with volume control that uses a long cable, however the reason cable is the main source of noise especially to do with control of voice signal. Wireless controller is an exception.
7. Balance connector (XLR) have better sound quality than the unbalance connector (RCA)
