DB Technologies DVA S1521N 21" Active Subwoofer, 1500W

The DVA S1521N is a powered 21“ subwoofer housed in a bass reflex enclosure that we tuned for accurate, ultra low-frequency response. It readily integrates into large DVA and DVX Series PA systems as a sub-bass unit or as a stacked subwoofer. Made of durable birch multiplex covered in robust black textured lacquer, the high-quality housing provides six carrying handles, an M20 pole mount, and bushings on the rear panel that accept casters. Pick-points for attaching DRK-10 and DRK-20 harnesses are built into the top panel to enable easy, safe stacking.
