The Fulcrum CS215L is built for audio engineers and system integrators who need high-output subwoofer performance in acoustically challenging spaces. Houses of worship, theater stages, and live event venues where rear LF buildup causes comb filtering or stage wash will benefit from the cardioid pattern achieved entirely through passive means. No additional amplifier channels, no supplemental drivers, and no DSP programming are required to achieve front-to-rear rejection, which significantly simplifies system design and reduces deployment time.

Two 15-inch woofers with 4-inch voice coils and ceramic magnets handle 2000 watts at 4 ohms, covering an operating range of 33 Hz to 141 Hz and reaching 137 dB peak SPL in half-space conditions. TQ Processing optimizes phase response and voicing so the CS215L integrates cleanly with full-range arrays without requiring manual phase correction at the console or processor. The compact footprint relative to the output it produces makes it a practical choice for fly rigs, under-stage fills, and installed subwoofer clusters where space is a genuine constraint.

Optional weather resistance extends deployment options to semi-outdoor venues and covered festival stages where ambient moisture is a concern. For system designers comparing the CS215L against conventional cardioid arrays built from multiple subwoofers wired in phase-offset configurations, the passive cardioid approach eliminates the complexity and potential failure points associated with those arrangements while delivering comparable directivity control from a single enclosure.
