Cardioid Subwoofers

Subwoofers with patent-pending Passive Cardioid Technology™

CS logo

Fulcrum Cardioid Subwoofers are designed with patent-pending Passive Cardioid Technology™ to eliminate excessive rear radiation by up to 10db without the extra cost, space requirements and inconvenience of active cardioid subwoofer systems. Their subcardioid behavior is produced by a meticulously conceived acoustical circuit which balances the position of the low frequency driver, the enclosure depth and volume, and specially constructed rear-mounted ports which include a calibrated resistive element.

By opting for a subcardioid pattern as opposed to a pure, hyper or super cardioid pattern, the rear rejection increases when the modules are deployed in a subwoofer array. Fulcrum Acoustic’s TQ™ processing is an integral part of the Cardioid Subwoofers’ design. Sound, innovative acoustical design combined with state of the art digital processing leads to exceptional clarity and precise transient response, even at very high sound pressure levels.

Our Cardioid Subwoofers are intended for permanent installation in a wide range of venues, including performing arts centers, houses of worship, sporting facilities and nightclubs.

CS118 18 inch Subcardioid Subwoofer

The CS118 incorporates Fulcrum’s patent-pending Passive Cardioid Technology to overcome one of the major challenges of many loudspeakers: excessive rear LF radiation. Unlike active cardioid loudspeakers, Fulcrum’s passive cardioid technology does not require an additional amplifier channel or additional transducer to achieve its impressive low frequency directional control: 10 dB of rear rejection over the subwoofer’s operating range.

Operating Range: 29 Hz to 137 Hz
LF Transducer: 18.0″ woofer, 4.0″ voice coil; ceramic magnet
Power Handling @ Nominal Impedance: 1200 W @ 8 Ω
Equalized Maximum SPL (peak / continuous): 136 dB / 130 dB (half space)
Dimensions (H x W x D): 756 x 624 x 762 mm / 29.8 x 24.6 x 30.0 in
Weight: 54.4 kg / 120.0 lb

CS121 21 inch Subcardioid Subwoofer

The CS121 incorporates Fulcrum’s patent-pending Passive Cardioid Technology to overcome one of the major challenges of many loudspeakers: excessive rear LF radiation. Unlike active cardioid loudspeakers, Fulcrum’s passive cardioid technology does not require an additional amplifier channel or additional transducer to achieve its impressive low frequency directional control: 10 dB of rear rejection over the subwoofer’s operating range.

Operating Mode: Single-amplified w/ DSP
Operating Range: 29 Hz to 143 Hz
