DB Technologies DVA S1521N 21-inch active subwoofer
Product no: DB-DVA-S1521N Bax Music Warranty: This product comes with a 3-year warranty.

General

The DVA S1521N is definitely a powerhouse that will make the earth tremble beneath you! This active 21-inch subwoofer produces the deepest tones that almost drop below the range of hearing, thanks to the enormous cone surface. 21-inch woofers are mainly used at large events where the deepest bass needs to be produced with a good range, without compromise.

Technical features of the DVA S1521N

The DVA S1521N is equipped with a 1,500W RMS Digipro G2 amp module, which easily offers the woofer more than enough power. The large 21-inch woofer has a powerful 4.5-inch voice coil, from which the deepest bass sounds are reproduced. A frequency range that goes as deep as 30 Hz is thus possible! Thanks to the internal DSP processor, the crossover frequency, delay and phase can all be adjusted - all of which are basic elements that are always helpful on location.

Construction and rigging

The S1521N has a birch multiplex construction, making it sturdy and robust. The housing is finished with a black acrylic textured lacquer which helps protect the subwoofer from scratches and other types of smaller cosmetic damage. Furthermore, you have the option of mounting a DKR10 or DRK20 rigging kit, so you can fly the subwoofer when necessary.

They plan to officially launch this active sub at the 2017 NAMM show next week. It has a cardioid directional pattern at its core which effectively prevents low frequencies from escaping via the rear or sides of the cabinet, resulting in more bass and a higher sound pressure level!
