The Mackie SRM 1850 is an active 18" subwoofer delivering 1600 W of intense power in an ultra-high output design that can shake the room. The professional-grade, interlay-braced all-wood enclosure provides tour level road-worthies with maximum low-frequency extension and punch.

SRM subwoofer features stereo XLR inputs, full-range and high-ass outputs plus a variable digital crossover that induces presets for SRM top boxes.

The Smart Protect DSP is also in place to protect your investment when things get used a little too hard. Get the high-output, air-moving lows you demand in a rock solid subwoofer.
