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.
- Subcardioid subwoofer module intended for permanent installation in a wide range of venues
- It includes a single, high power 21 inch direct-radiating woofer in a compact enclosure
- A variety of mounting points facilitate supsension via shoulder eye bolts or a yoke bracket
