architectural and engineering specifications
The loudspeaker system shall be of the three-way bi-
amp 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. The loudspeaker shall be operated
with a separate electronic controller providing a 650Hz
crossover between low and mid/high frequency
sections. 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 LF,
150W AES, 600W peak MF/HF.
Rated impedance shall be 8 ohms LF, 16 ohms MF/HF.
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 31.5kg (69lbs).
The loudspeaker system shall be the Martin Audio W3.
