QM 212AS Powered Compact Sub Bass

Big bottoms, small footprint

How to get 18" bass from a 12" driver? The same way you get 16 Hz from a 4" diameter organ pipe; resonate a column of air.  The QM 212S is a multi chamber band-pass design with the additional hybrid direct radiating pressure chamber loading of its two purpose designed 12" bass drivers. The two transducers couple to achieve tight and percussive mid bass "punch" while the low chambers produce the resonant low bass output.

An internal 800 watt processor/amplifier and adjustable stereo crossover with variable low pass filter makes matching the QM 212AS with any powered or passive system easy.

This is all packed into a very compact rectangular cabinet constructed of multi-ply birch plywood and finished in hard wearing textured polyurethane paint . It features a pole-mount receptacle, neoprene skids to grip timber stages.
