30 Hz-150 Hz
K18 is a high-output, self-powered low-frequency enclosure. This compact, powerful cabinet can achieve impressive SPLs and sets a new precedent for output at this size. The integral high-efficiency, Class D amplifier maximizes performance with enhanced ease-of-use thanks to onboard DSP settings, making the K18 a suitable candidate for both 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.
