BassBoss DJ18S-MK3 Single 18 inch Powered Subwoofer

The DJ18S-MK3 is the tall, narrow single-18 in the range, sized to sit beside a booth or against a wall rather than sprawl across the floor. Its 18-inch neodymium driver on a 4.5-inch CCAW voice coil goes down to 27 Hz within 3 dB, deeper than the wider SSP118, with 129 dB sustained and 132 dB peak output from a 2,500-watt Class D amplifier.

At 110 pounds it is a one-person load, and the interlocking foot pockets let cabinets stack squarely for larger rooms, with cardioid patterns available once there is more than one. The 96 kHz DSP carries eight pushbutton presets on the box and a hundred more over the network via ControlBASS, with multi-stage limiting, thermal, short-circuit, and DC offset protection running underneath. Power is auto-sensing 100 to 240 VAC on weather-sealed powerCON connectors, inside a polyurea-coated birch enclosure.
