NEW CS218L Dual 18″ Subcardioid Subwoofer from Fulcrum Acoustics




The CS218L is a low profile, dual 18-inch Subcardioid subwoofer module intended for permanent installation in a wide range of venues. Its premium, high power transducers are physically engaging, yet are musically articulate enough to reproduce the subtlety and harmonic nuance of an upright bass or the low strings of a piano. Twelve M10 mounting points facilitate either horizontal or vertical overhead suspension. Four vibration isolation feet prevent spurious vibrations and “walking” in horizontal ground stack applications.

The CS218L incorporates Fulcrum’s patented Passive Cardioid Technology to address one of the major challenges of many direct-radiating subwoofers: 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.

The 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 CS218L 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. The required digital signal processing can be provided by one of many supported platforms.
