Low-grade plastic speakers because of its thin box, can not overcome the resonance, no sound quality at all (there are also some well-designed plastic speakers are far better than inferior wooden speakers); Wooden speakers reduce the sound dye caused by the resonance of the box, and the sound quality is generally better than that of plastic speakers.

Usually, multimedia speakers are dual-unit binary frequency design, a smaller speaker is responsible for the output of the middle and high, and another larger speaker is responsible for the output of the low.

The selection of speakers should consider the material of the two speakers: the treble unit of the multimedia active speaker is now based on the soft ball top (in addition to the titanium film ball top for analog sound sources, etc.), which works with the digital sound source to reduce the stiffness of the high-frequency signal, giving people a gentle, smooth, delicate feeling. Multimedia speakers are now mostly soft ball tops such as high-quality silk film and low-cost PV film.

Subwoofer It determines the characteristics of the sound of the speaker, the choice is relatively important, there are the following common: paper basin, and coated paper basin, paper base wool basin, compact basin and so on.

Paper basin sound natural, cheap, good rigidity, light material, high sensitivity, the disadvantage is poor moisture resistance, manufacturing consistency is difficult to control, but the HiFi system in the paper basin manufacturing everywhere, because the sound output is very average, good reducibility.

Bulletproof cloth, has a wide frequency response and low distortion, is the choice of people who love strong bass, the disadvantage is high cost, complex production process, sensitivity is not high light music effect is not very good.

Wool woven basin, soft texture, it is very good for soft music and light music performance, but the bass effect is not good, lack of strength and shock.

PP(polypropylene) pot, it is widely popular in speakers, good consistency and low distortion, and all aspects of performance are commendable. In addition, there are fiber vibrating films and composite vibrating films, which are rarely used in popular speakers due to their high prices.

The size of the speaker is naturally the bigger the better, and the large-caliber woofer can have a better performance in the low-frequency part, which can be selected in the purchase. Speakers made with high-performance speakers mean lower transient distortion and better sound quality. The speakers of ordinary multimedia speakers are mostly between 3 and 5 inches. Speakers made with high-performance speakers also mean lower transient distortion and better sound quality.
