Product Overview

High-Tech, Multi-Task Powered 21" Subwoofer w/DSP & Power Output

KMT21 is much more than a standard 21” powered subwoofer. The amplifier mounted on board is Class D, delivering 2 x 2000 W at 4 Ohm. 

The unique four-corner port configuration gives symmetrical back loading to the speaker for extended bass response with very low distortion. This also gives incredible structural strength to the cabinet despite its light weight. 

The rear panel provides input for a balanced line signal, a balanced microphone signal with phantom power and digital signals in AES/EBU protocol and also on an XLR for ease of cabling.
