architectural and engineering specifications
The loudspeaker system shall be of the three-way type
consisting of one 15" (380mm) direct radiating reflex
loaded low frequency transducer, one 6.5" (165mm)
cone driver mounted on a constant directivity horn flare
with integral toroidal waveguide and one 1" (25mm)
exit HF compression driver mounted on a constant
directivity horn in a trapezoidal plywood enclosure. The
enclosure shall be fitted with an integral pole mounting
socket and threaded inserts for wall and ceiling
mounting. Low and mid frequency sections shall be
integrated by an internal 650Hz passive crossover
network and mid and high frequency sections shall be
integrated by an internal 3.3kHz passive crossover
network.
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
55Hz-18kHz ±3dB.
High frequency dispersion at -6dB points shall be
65˚H x 40˚V.
Power handling shall be 400W AES, 1600W peak.
Rated impedance shall be 8 ohms.
Maximum SPL measured at 1 metre on axis shall be
125dB continuous, 131dB peak.
Dimensions (W) 435mm x (H) 708mm x (D) 425mm
(17.1ins x 27.9ins x 16.7ins).
Weight 34.5kg (75.9lbs).
The loudspeaker system shall be the Martin Audio W3P.
