At InfoComm, Fulcrum Acoustic is launching the FL283 line array module. The FL283 uses dual 8-inch horn-loaded woofers and three 1.5-inch compression drivers in a compact enclosure. The enclosure is shaped to accommodate up to 20 degrees of splay between adjacent boxes, allowing for more sharply curved arrays than comparable line arrays. The FL283 also incorporates Fulcrum’s 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. It achieves impressive low frequency directional control without the loss of efficiency that characterizes active cardioid devices.
Each FL283 module is configured for full-range passive operation at 16 ohms, allowing eight units to be driven from a single power amplifier channel.
