architectural and engineering specifications
The loudspeaker system shall be of the two-way passive
type consisting of two 6.5" (165mm) direct radiating
reflex loaded low frequency transducers and one triple
element high frequency line array coupled with a
proprietary diffusion phase plug mounted in a multi-
angled plywood enclosure. The enclosure shall be fitted
with an integral pole mounting socket and supplied with
a flying yoke. Input connector configuration shall be
externally selected by a switch at the rear of the
enclosure. Low and high frequency sections shall be
integrated by an internal 1.2kHz 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
80Hz-18kHz ±3dB.
High frequency dispersion at -6dB points shall be
120˚H x 40˚V.
Power handling shall be 200W AES, 800W peak.
Rated impedance shall be 8 ohms.
Maximum SPL measured at 1 metre on axis shall be
115dB continuous, 121dB peak.
Dimensions (W) 480mm x (H) 212mm x (D) 344mm
(18.9ins x 8.4ins x 13.6ins).
Weight 12kg (26.4lbs).
The loudspeaker system shall be the Martin Audio
WTUB.
