Type and Design
Type: Depending on whether an amplifier is built-in, subwoofers can be divided into two types: active (active) and passive (passive). The active subwoofer is equipped with an amplifier, which can directly obtain low-level music signals from the subwoofer output of the AV amplifier; The passive subwoofer needs to be driven by an external amplifier.
Design: There are various designs for ultra-low speakers, including enclosed, bass reflex, ribbon type, and transmission line type. Each design has its own characteristics, such as a sealed speaker that responds quickly and can withstand high power; Bass reflex speakers have low distortion and can withstand high power.

Ultra low speaker is a specialized speaker in the audio system, mainly used to enhance the sound effect in the low frequency range. The playback frequency range is usually between 20Hz and 150Hz. Strictly speaking, frequencies below 20Hz are called "super" bass, but generally speaking, super bass refers to bass with a playback frequency lower limit above 20Hz.
