architectural and engineering specifications
The loudspeaker system shall be of the three-way type
with switchable active/passive HF. The low-mid section
shall consist of one 12" (300mm) cone transducer
mounted on a horn flare with a precision moulded
waveguide. The high-mid section shall consist of a 6.5"
(165mm) cone driver mounted on a constant directivity
horn flare with integral toroidal waveguide. The high
frequency section shall consist of a 1" (25mm) exit HF
compression driver mounted on a constant directivity
horn which shall be internally protected for signals
below its intended passband by a power and frequency
matching network. The enclosure shall be of the heavily
braced multi-laminate trapezoidal plywood type.
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
120Hz-18kHz ±3dB.
High frequency dispersion at -6dB points shall be
55˚H x 30˚V.
Power handling shall be 300W AES, 1200W peak Low-
mid, 150W AES, 600W peak High-mid /(HF), 60W AES,
240W peak HF.
Rated impedance shall be 8 ohms Low-mid, 16 ohms
High-mid /(HF), 16 ohms HF.
Maximum SPL measured at 1 metre on axis shall be
129dB continuous, 135dB peak.
Dimensions (W) 556mm x (H) 799mm x (D) 911mm
(21.9ins x 31.5ins x 35.9ins).
Weight 71kg (156.5lbs).
The loudspeaker system shall be the Martin Audio
W8C.
