Personal preferences – what’s important to you? Bass, how loud it is, or just quality sound? Every subwoofer in the market is manufactured to suit the needs of the consumer regarding price, space, music preferences etcetera. Keep that in consideration so that your needs are met.

Box – each subwoofer has a different box which determines the sound of the stereo. There are four boxes available; bandpass, sealed, aperiodic box, and ported. Each box has its advantages and disadvantages. What is essential is your needs.

The number of coils – subwoofers has a dual or single coil. A dual coil will offer more options when wiring the system.

Frequency – a low-frequency sound requires a high-frequency speaker and vice versa.
