DRM18S

The Mackie DRM18S is an 18" powered subwoofer with a 2000W Class-D amplifier, the low end under a DRM system or any full-range rig that needs more weight. An 18" high-excursion woofer sits in a braced 18mm plywood cabinet with precision-tuned ports, so output stays clean at the levels where smaller subs start to compress.

Advanced Impulse DSP applies acoustic correction that holds reference quality response even at high SPL, and the DRM Control Dashboard puts it all behind one knob and a full-color display. The variable crossover point matches the sub to any top cabinet, with a dedicated DRM mode that tailors the tuning for DRM full-range loudspeakers. Polarity invert and alignment delay handle stacking and time alignment, and six user presets store settings for the rooms and events you repeat.

Cardioid mode is the feature mobile DJs and production crews reach for most. It sets up a directional subwoofer array so bass hits the dance floor instead of the stage and the neighbors, which cleans up the mix on stage and keeps volume complaints down.

Dual independent input channels include full-range direct and high-pass outputs, so the sub feeds your tops without an outboard processor. A universal supply with Power Factor Correction keeps performance steady on unstable AC, and next-gen protection circuitry guards the amp and driver. At 90 lb, it flies with the optional FB100 fly bar and FKDRM18S flyware kit, or takes an M20 pole for tops above it.
