architectural and engineering specifications
The loudspeaker system shall be of the two-way
switchable active/passive type consisting of one 12"
(300mm) direct radiating reflex loaded low frequency
transducer 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. Active or
passive operation shall be selected by a switch at the
rear of the enclosure. In active mode the loudspeaker
shall be bi-amped and operated with a separate
electronic controller. In passive mode, low and high
frequency sections shall be integrated by an internal
1.5kHz 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
60Hz-18kHz ±3dB.
High frequency dispersion at -6dB points shall be
70˚H x 40˚V.
Power handling shall be 300W AES, 1200W peak
(LF/HF), 60W AES, 240W peak HF
Rated impedance shall be 8 ohms LF/(LF+HF),
8 ohms HF.
Maximum SPL measured at 1 metre on axis shall be
122dB continuous, 128dB peak.
Dimensions (W) 365mm x (H) 554mm x (D) 364mm
(14.4ins x 21.8ins x 14.3ins).
Weight 24kg (53lbs).
The loudspeaker system shall be the Martin Audio W2.
