When choosing a subwoofer, the material of the subwoofer is very important, and its pros and cons determine the sound quality and the level of effect. Now let me choose the material for making the subwoofer speaker as follows:

The low-grade plastic subwoofer speaker can't overcome the resonance because of its poor plastic case, so the sound quality is not good, and the effect is very poor. The wooden subwoofer speaker reduces the sound of the box resonance, and the sound quality is generally better than the plastic speaker. Usually the multimedia speakers are dual-unit two-way design, one smaller speaker is responsible for the mid-highs output, and the other larger speaker is responsible for the mid-bass output.

Choosing the subwoofer speaker should consider the material of these two speakers: the high-pitched unit of the multimedia active speaker is now dominated by soft domes, and the multimedia speakers are now soft ball tops with better quality silk film and lower cost PV film. Mostly. The woofer determines the characteristics of the sound of the speaker and is relatively important to choose.

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