Description
-
Small but mighty! Fosi Audio M04 is a 100w mono-channel class D subwoofer amplifier, with a SUB/PBTL switch you can select a subwoofer bass amplifier or full frequency mono amp, can be connected to an active/passive subwoofer and passive speaker.

The power switch was integrated into volume control, we made it small but supply an in-wall or stand-alone subwoofer the power it needed so you can experience room-shaking low-frequency impact (bass) on movies and music soundtracks.
