This article is reproduced for the purpose of the research study, if you violate the copyright and .other interests, please notify us immediately. <br> <br> First, look at the <br> <br> Careful observation of the entire box look can obtain such as crafts, box material, box sealing, speakers of the caliber and quality .information, and even the divider can be seen from down-hole. Look at the speaker's bonded layer, whether there is a clear bubble, scratches, curling edges, and other phenomena; joints and tidy; box some plastic products whether coarse, such as .down-tube wall is solid, the surface is smooth. From these nuances, often on the whole case quality location started to take shape. Then from the speaker panel seams carefully discern the case materials, under normal circumstances is easy to distinguish, wood is .currently on the market of multimedia speaker mostly wood wood, but also has good and bad, although some low-grade speaker for wood, but often the density of the lower particle board, and a thin sheet metal. It is through the seams as you .cannot see it, you can also use the fingers in the body cavity of box wall knocked a knock, if sheet thick, density is high, the sound should be low and no clear cavity. Also, see the enclosure in front panel, there are .often some of the speakers for the pursuit of aesthetic appearance and reducing production complexity with plastic Panel (because the plastic products of plasticity strong, easy to install speakers and control knob), however the plastic Panel in addition to the beautiful made out of nothing: .Panel of resonant serious, a large, the knob hole gap even led holes can be called "until I get" no sound at all, from that point of view, advise you not to buy speakers to Maung taking too much "box". Finally ., don't forget most dual mono speaker panel NET cover can be removed. (Be careful, preferably merchants agree to) remove the net cover can observe speakers, although the finished box has failed to see the speaker magnet, but from the cone and .fold the ring material to estimate the quality of the woofer. If the cone and fold ring-one is pressed pulp material, it is a common low-grade speaker. High point of the speakers fold folded around common rubber ring, substrate reduction rings or .foam Pack ring, although these fold ring in sensitivity may not and cone folding cycles, but in the resonant frequency, quality, frequency response, and other targets than cone folding ring. As for conical tub of material, each has his merits, benevolent see .benevolence, Moses. <br> <br> Second, OK <br> <br> OK one more weight, this approach is a bit of "Earth", but very practical. Although the quality of the speakers are not necessarily proportional to the .weight, the weight at least able to explain the business production sound material of the "weight" (I want, and then evil "JS" are still not in the box on a brick!). The speaker's power to a large extent affected by .magnets, magnet size of course directly reflected in weight; enclosure in (thickness, density), the better, the greater the weight is inevitable; and then to the power amplifier circuit, the entire system of output power ultimately derived from the power supply transformer ., power transformer capacity will playback time (particularly large volume) dynamic distortion appears obvious, "insufficiency" feeling, and the transformer capacity are essentially proportional to the weight. In conclusion, the speaker quality and weight is basically the same. When selects and purchases ., pick the "heavy" rational! <br> <br> 3. listen <br> <br> Buy speakers finally is used to listen, hear this link is indispensable. The majority of PC Shaoyou not audio enthusiasts, does not have " .golden ears ", didn't expect to burn music sound. Just hope it in replay without obvious defects. I think that for General multimedia speakers, listen to focus on two aspects: first, change the volume for audition. In large volume, tone .has no obvious mutations, clear tone mutation is usually a box of mechanical resonance, belongs to an typical defects. In addition, in volume also note sounds (especially bass) with and without dynamic distortion; in small volume can inspect Snr, signal to noise .ratio (S / N) refers to the signal power and noise power ratio, it is the power amplifier is an important performance indicator, signal to noise ratio size main subject filter circuit, amplifier IC, line layout and production process. Determine the size of .the simple-to-noise ratio is to reduce the volume or simply point to signal source, listen to the speaker of the size of the background noise. Background cleaner is better, some poor speakers without any input significant buzz, this mostly because manufacturers boost .on the filter (filter capacitor size too small). The second is to change the pitch of the audition. Can make use of the software adapts to tone, enhance treble section, listen to the treble is clear and bright, the inmates; enhance the .low frequency bass components to investigate whether there is a sense of strength, some 2.1 speakers to the subwoofer is chaos, ROAR, upgrading the baritone to observe the crossover point is there no sound defect. Finally you can enter your own familiar music to judge whether .the convergence of bass speakers, naturally in a particular frequency band is there lacking - - - - complete the above mission, if you are satisfied, the rest is a hard bargain, took the silver..
