The FLS115 is a subcardioid line array subwoofer module intended for permanent installation in a wide range of venues. It includes a single, high power 15 inch direct-radiating woofer in a compact enclosure. The FLS115’s rigging is designed to easily attach to the FL283 subcardioid line array module. The enclosure is shaped to accommodate up to 20 degrees of splay between adjacent enclosures, allowing for more sharply curved arrays than comparable line array subwoofers. Up to twelve modules may be suspended with a 10:1 design factor.
The FLS115 incorporates Fulcrum’s patent-pending Passive Cardioid Technology™ to overcome one of the major challenges of most line arrays: excessive rear LF radiation. Unlike active cardioid loudspeakers, Fulcrum’s passive cardioid technology does not require an additional amplifier channel or additional enclosure volume to achieve its impressive low frequency directional control—6 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 as a curved line array.
Fulcrum Acoustic’s TQ™ processing is an integral part of the FLS115 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.
