Line Array

Line array modules for a wide range of venues

Linear-Ray

The FL283 and FLS115 incorporate 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.

The subcardioid behavior is produced by a meticulously conceived acoustical circuit which 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 now offers the infinitely adjustable Polar Focus® KESTREL fly bar. Polar Focus offers a host of accessories, including XY Grid® pan control fittings and numerous fittings designed to suspend an array from structure.

FL283 Dual 8 inch Subcardioid Line Array Module

The FL283 is a subcardioid line array module intended for permanent installation in a wide range of venues. It includes dual 8-inch horn-loaded woofers and three 1.4-inch compression drivers in a compact enclosure. The enclosure is shaped to accommodate up to 20 degrees of splay between adjacent enclosures, allowing for more sharply curved arrays than comparable line arrays. Each FL283 module is configured for full-range passive operation at 16 ohms, allowing up to eight units to be driven from a single power amplifier channel. Up to twelve modules may be suspended with a 10:1 design factor.

Operating Mode: Single-amplified w/ DSP
Operating Range: 54 Hz to 19.6 kHz
HF/LF Transducers: 3x 1.4” titanium diaphragm, neodymium magnet compression driver; 2x 8.0” ceramic magnet cone driver, 2.0” voice coil
Power Handling @ Nominal Impedance: HF/LF 500 W @ 16 Ω
Equalized Maximum SPL One Module (peak / continuous): 128 dB / 122 dB
Equalized Maximum SPL Eight Modules (peak / continuous): 146 dB / 140 dB
Dimensions (H x W x D): 324 x 586 x 491 mm / 12.8 x 23.1 x 19.3 in
Weight: 25.6 kg / 57.0 lb

 

FLS115 15 inch Subcardioid Subwoofer

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.

Operating Mode: Single-amplified w/ DSP
Operating Range: 31 Hz to 135 Hz
LF Transducer: 15.0” woofer, 4.5" voice coil; neodymium magnet
Power Handling @ Nominal Impedance: 1500 W @ 8 Ω
Equalized Maximum SPL (peak / continuous): 131 dB / 125 dB (half space)
Equalized Maximum SPL (peak / continuous): 125 dB / 119 dB (whole space)
Dimensions (H x W x D): 469 x 586 x 491 mm / 18.5 x 23.1 x 19.3 in
Weight: 25.6 kg / 57.0 lb
