What is an active subwoofer and what is a passive subwoofer?

                What is an active subwoofer and what is a passive subwoofer?

Active subwoofer: refers to a subwoofer with a power amplifier (amplifier) inside the box.

advantage:

1. The workmanship is generally small and easy to install

2. Because the speaker has its own power amplifier inside, it can be driven by directly connecting the audio source without adding a power amplifier.

3. The price is generally more affordable.

shortcoming:

1. The output power is relatively small, and the music expression is not very strong

2. The structure of the circuit is relatively simple

Passive subwoofer: refers to the subwoofer that only contains speaker units and frequency dividers inside the cabinet, without power amplifiers.

advantage:

1. The structure of the speaker unit is complicated, and the material is relatively good

2. Large output power, strong low-frequency signal output, and strong music expression

shortcoming:

1. Large in size, bulky, and takes up a lot of space

2. The price is more expensive than the active subwoofer

After reading the above introduction, I think everyone should have a clearer understanding of "passive subwoofer" and "active subwoofer". Here is some additional purchase information. Active subwoofers are more suitable for beginner car audio enthusiasts, or friends who do not have high requirements for low frequencies. The passive subwoofer is a must-have car audio modification equipment for friends who like strong DJs and dance music!
