FL283T Dual 8 inch Subcardioid Line Array Module
- HF/LF Transducers: 3x 1.4” titanium diaphragm, neodymium magnet compression driver; 2x 8.0” ceramic magnet cone driver, 2.0” voice coil
- Equalized Maximum SPL (peak / continuous): 128 dB / 122 dB (one module); 146 dB / 140 dB (eight modules)
The FL283T incorporates Fulcrum’s patented* 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.
The subcardioid behavior is produced by a meticulously conceived acoustical circuit that balances the horn loading of the low-frequency drivers, 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 FL283T design. Sound, innovative acoustical design combined with state of the art digital processing leads to the 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. Note that FL Series loudspeakers must use Level 1 processing.
