W8LGRIDASSEMBLY	Flying grid
HAM09001	Ground stack bar

The loudspeaker system shall be of the three-way horizontally formatted line array type. The low frequency section shall consist of one 15" (380mm)/4” (100mm) ultra-long excursion cone transducer, with neodymium magnet driver, horn and reflex loaded in a Hybrid™ bass system. The mid frequency section shall consist of two 8” (200mm) cone drivers coupled to a constant directivity horn using toroidal phase devices. The high frequency section shall consist of four 1" (25mm) exit HF compression drivers, with neodymium magnets, mounted on vertically coupled waveguides with a constant directivity horn. The enclosure shall be constructed of heavily braced multi-laminate plywood with all flying hardware integral and captive. The loudspeaker system shall be supplied with a wheelboard that shall attach to the front of the enclosure with slam latches to facilitate ease of deployment. The loudspeaker shall be operated with a separate dedicated electronic controller.

Performance of the loudspeaker system with its electronic controller shall meet or exceed the following criteria: Frequency response measured 1 metre on axis shall be 35Hz-18kHz ±3dB.

High frequency dispersion at -6dB points shall be 90°H x 7.5°V.

Power handling shall be 1000W AES, 4000W peak LF, 400W AES, 1600W peak MF, 200W AES, 800W peak HF.

Rated impedance shall be 8 ohms LF/MF/HF.

Maximum SPL measured at 1 metre on axis shall be 136dB continuous, 142dB peak LF, 135dB continuous, 141dB peak MF, 142dB continuous, 148dB peak HF.

Dimensions (W) 1314mm x (H) 490mm x (D) 755mm (51.7ins x 19.3ins x 29.7ins).

Weight 123kg (271lbs).
