Mackie SR18S 18-Inch 1600W Powered Subwoofer

The SR18S drives an 18-inch driver with a 1600W Class-D amplifier, reaching a 33-200Hz response and 133dB max SPL for full-range PA systems that need real low end. Three onboard DSP voicing modes, Flat, Deep, and Punch, retune it for balanced coverage, electronic music, or rock and band mixes without an outboard processor.

Stereo XLR inputs feed stereo full-range and high-pass XLR outputs for looping in tops, and a variable crossover, polarity invert switch, and adjustable level control (-6dBU to +6dBU) handle system tuning. At 74.5 lb it\'s built for touring and installed sound alike.
