architectural and engineering specifications
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).
The loudspeaker system shall be the Martin Audio W8L
Longbow.
