Product Overview

Active Subwoofer 18" 1000W

The bandpass subwoofer DVA S10 dp c* is equipped with a single 18" woofer of the newest generation, driven by a 1000W digipro digital power amp. Using the optionally available flyware, up to two DVA S10 can be flown mounted to the DRK-10 rigging kit. Further the DVA S10 can be used as a compact PA system together with either 3x DVA T4 on a speaker pole or 2x DVA S10 and 4-6 DVA T4 as a Groundstack.

* c = equipped with ceramic magnet

The DVA S10 subwoofer is equipped with powerful woofers and a 4” voice coil for extremely high sound pressures. Double ventilation provides an optimum of cooling, a minimum of power compression at high reliability. The woofers are fibreglass reinforced and have a triple-roll coil embedded in a perfect edging with constant geometry. This combination makes an extreme peak-to-peak steering of up to 48mm possible.

The highly efficient digital power amps of both subwoofers do not need a fan cooling system. The integrated crossover ( 90/120Hz switchable), professional Power-Con mains connectors and a slot on the back of each subwoofer for the optional SDD delay-module are just a few highlights. Mounting points for the DRK-10 frame and threads on the back for taking the optional blue-wheels complete the picture.

DVA S10 dp c cardioid bass setup with the SDD module
A cardioid setup comprising the SDD module and three DVA S10 subwoofers on each side keeps levels down on stage and affords you far greater control over low-frequency coverage in the audience area. Never before has this innovative solution – which until today entailed much effort and audio gear – been so easy to achieve with such professional results.
