Speaker materials and dimensions

Low-grade plastic speaker whose body thin, cannot overcome resonance, no sound at all (or some design good plastic speakers are far more likely than poor quality wooden speaker); wooden speaker lowered-cabinet resonances caused by bass, sound speakers generally better than plastic. Typically multimedia speaker are double-2 crossover design, a small speaker is responsible for the output in the treble, and another larger speaker is responsible for the bass output. Selection of speakers should consider the two horns of material: multimedia active speaker's treble unit now mainly soft ball (in addition to analog audio source of titanium ball, etc.), which, in conjunction with digital audio sources reduces high-frequency signal a sense of hard, soft, smooth, and smooth feel. Multimedia speaker system is the quality better silk film and lower-cost, flexible PV membrane dome. Bass unit which determines the characteristics of the speaker's voice, select relative importance, the most common are the following: Cone, packing tape, paper-based wool basins, tight repression basin, etc. Cone Giga natural, cheap, good rigidity, materials lighter high sensitivity, the disadvantage is moisture-proof of poor, consistency is difficult to control the time of manufacture, but top HiFi system made of paper basin, because the sound output are very average, good. Bullet-proof fabric, with wide frequency response and low distortion, strong bass who was passionately fond of choice, the disadvantage is the high costs, making complex, sensitivity is not high light music effect is not very good. Wool woven basin, soft texture, its soft music and light music performance is excellent, but the bass is poor, weak and shocking. PP (polypropylene), it is widely popular in high-end speakers, uniformity is good distortion is low, all aspects of performance. In addition there are like fiber diaphragm and composite material diaphragm such as prices rarely applied to popular speaker. Speaker size natural is better, large caliber bass speakers are in the low-frequency component for better performance, this is optional, you can select. With high-performance speaker manufacturing speakers means lower transient distortion and better sound quality. Ordinary multimedia speaker bass speaker speakers are between 3 to 5 inches. With high-performance speaker manufacturing of speakers also means lower transient distortion and better sound quality.
