Low-end plastic speakers have no sound quality due to their thin cabinets and inability to overcome resonance (and some well-designed plastic speakers are far better than inferior wooden speakers); wooden speakers reduce the sound stain caused by the resonance of the cabinet The sound quality is generally better than plastic speakers. Usually multimedia speakers are dual-unit two-way frequency design, a smaller speaker is responsible for the output of midrange and treble, and another larger speaker is responsible for the output of midrange and bass.

The selection of speakers should consider the materials of these two speakers: the tweeter of the multimedia active speaker is mainly domed (in addition to the titanium membrane dome used for analog sound sources, etc.), which can reduce high frequencies with the digital sound source. The stiffness of the signal gives a gentle, smooth and delicate feeling. Multimedia speakers are now dominated by soft domes with better quality silk films and lower cost PV films.

The woofer determines the characteristics of the sound of the speaker. The selection is relatively important. The most common ones are the following: paper cones, glue-coated paper cones, paper-based wool basins, and compact pressure basins.

 Paper cones have natural sound, cheap, good rigidity, lighter materials and high sensitivity. The disadvantages are poor moisture resistance and difficult to control consistency during manufacturing. However, paper cones made in top HiFi systems are everywhere because the sound output is very average. Good reduction.

Bulletproof cloth, with wider frequency response and lower distortion, is the first choice for those who love strong bass. The disadvantages are high cost, complicated production process, low sensitivity and low music effect. The wool woven basin has a soft texture, and it is very good for soft music and light music, but the bass effect is not good, lacking strength and shock.

The size of the speaker is naturally the larger the better, the large-diameter woofer can perform better 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. Ordinary multimedia speakers and woofer speakers are mostly between 3 and 5 inches. Speakers made with high-performance speakers also mean lower transient distortion and better sound quality.
