Product Overview

Active Subwoofer 18"/15 Cardoid

The DVA S2585N is a compact subsystem featuring a cardioid layout designed for utmost directivity. The system consists of two separate chambers, one loaded with a forward facing 18“ woofer and another with a rearward facing 15“ woofer. The integrated digipro(R)G2 digital power amps provide 2500W total output power. The high-quality DSP filters signals and controls the speakers to deliver a remarkably authentic audio image and faithful transient response. The housing is ready to fly – the optional SRK10 Rigging Kit is all it takes to put up flown cardioid sub arrays.

Cardiod- Design
Many systems lack low-frequency directivity and, as a result, are plagued by interference and annoying noise. The S2825N, in contrast, was engineered specifically for enhanced low-frequency directivity. And it not only sounds great, it is also easy to handle and transport.
