The white DVA S09DP from dB Technologies is a 15" 1000 watt powered subwoofer that is designed to deliver true, tight, and punchy bass response. With a height of 44 cm, it can be flown to keep the rig's footprint inconspicuous.
The speaker features an active stereo crossover with two cutoff frequencies to choose from: 90Hz and 120Hz. It also features a phase inversion switch, one PowerCon socket to connect to the mains power supply, and two PowerCon outputs to connect satellite speakers.
