Product Description:

dB Technologies DVA S1521N 21Inch 1500W RMS Active Subwoofer


DVA S1521N Subwoofer, 21“ Bassreflex
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 housing 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.


Active Subwoofer 1500 Watt RMS

Top-notch 21“ woofer
Serving as the unit’s transducer is a state-of-the-art 21” woofer with 4.5“ voice coil.
This combination of high-quality materials and sophisticated magnetic drivers fields some pretty impressive results.
Even very low bass frequencies are rendered with pinpoint precision and hairtrigger transient response, treating audiences to a breathtaking audio experience.
