VS 21 SUB

21” subwoofer  / 1.000 W (RMS)

The VS21SUB is a subwoofer system in a rectangular chassis for fixed installations and mobile use. The cabinet is equipped with a high performance 21" speaker. The integrated tripod base (M20) enables the use of a distance rod in combination with a MF/HF cabinet as a system. The flexible VS21SUB suits for speech and music applications as subwoofer speaker in sound reinforcement systems. The chassis is constructed from 15 mm plywood (birch) and covered with black NOVA PolyCoat© finish. The cabinet is equipped with four grip handles and a front grill with transparent charcoal foam backing. Two speakon connectors (NL4) are mounted at the rear side of the chassis for signal input (input), signal link (link) and signal output (output) to a satellite speaker if using the integrated passive crossover. The power rating of the VS21SUB is 1.000 W (RMS), the impedance is 4 ohms.
