Six user memory locations allow settings to be saved and recalled for repeat setups.\u003c\/p\u003e\u003cp\u003eDual input channels, direct outputs, and high-pass outputs make the DRM18S practical for building compact PA systems with powered top speakers. Use the DRM Top crossover mode when pairing it with compatible Mackie DRM loudspeakers, or select a variable crossover for other full-range speakers. Multiple DRM18S units can also be configured for cardioid operation to direct more low-frequency energy toward the audience area.\u003c\/p\u003e\u003ch3\u003eKey Features\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003e18-Inch Ferrite Woofer:\u003c\/strong\u003e Provides dedicated low-frequency reinforcement for professional PA systems.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e2000W Peak Class-D Amplifier:\u003c\/strong\u003e Supplies integrated power without requiring an external amplifier.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAdvanced Impulse DSP:\u003c\/strong\u003e Applies acoustic correction and system processing within the subwoofer.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDRM Control Dashboard:\u003c\/strong\u003e Uses a color display and rotary control for setup access.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eVariable Crossover:\u003c\/strong\u003e Helps match the subwoofer with DRM or non-DRM tops.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCardioid Mode:\u003c\/strong\u003e Supports directional multi-subwoofer arrangements using multiple DRM18S units.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eDesign \u0026amp; Installation\u003c\/h3\u003e\u003cp\u003eThe DRM18S uses an 18 mm plywood cabinet with internal bracing, a black Polyurea finish, and a powder-coated 16-18 gauge perforated-steel grille.
