The K218 is a high-output, dual 18" self-powered low-frequency enclosure. An integral high efficiency, class-D amplifier offers tight low-frequency extension while user-selectable presets maximize ease of use, making K218 a suitable candidate for a wide range of portable and installed applications. In addition to 90 Hz and 130 Hz low-pass filters, the onboard DSP enables simple cardioid configurations. Non-skid, high-density stacking rubber feet and rear-mounted transport casters are designed with the end user in mind. The high-grade, void-free Baltic birch cabinet is finished with a tour-grade, high-impact EXL polyurea coating.
