Markaudio AS 121S

The AS 121S loudspeaker is an active subwoofer with 12” B&C custom neodymium speaker.
The heart of the loudspeaker is a 800 watt rms digital power amplifier (AES standard) with switching power unit.
Dynamic control is handled by a digital processor which, suitably programmed, optimizes sound across the entire frequency range and maximizes component reliability.
The AS 121S active subwoofer is equipped with active bypass/high outputs to guide AS 601 or AS 602 satellites.
