The loudspeaker shall be a two-way,
in-ceiling system consisting of an 8” low frequency transducer and
a 1” dome high frequency transducer mounted in a ported enclosure.
The enclosure shall comprise a pressed steel backcan with a UL94V-0
fire-rated moulded baffle. The transducers shall be protected by a
removable, perforated steel grille.
Input connection shall be made via a
four-pin rising-clamp plug and socket with loop-through capability to
enable pre-wiring with up to 2.5mm2 cable prior to installation. The
connector shall be protected from fire by a steel cover with a
clamped cable entry. An attachment tag on the backcan shall enable
direct attachment to the building structure as a secondary support.
The loudspeaker shall include a steel
support ring and tile rails.
Dispersion shall be 90° conical up
to 7kHz. The on-axis frequency response shall be 80Hz-18kHz +/- 3dB
and the loudspeaker shall produce a maximum SPL of 116dB peak
calculated at 1 metre. Power handling shall be 125W AES, 500W peak.
The loudspeaker shall be equipped with
a transformer for 70V or 100V line operation, with taps selected by a
rotary switch on the front baffle. The switch shall also provide for
16 ohm low impedance operation of the loudspeaker.
Dimensions (OD x D) shall be 354mm x
258mm (13.9ins x 10.2ins). Weight shall be 6.7kg (14.8lbs).
The loudspeaker shall be the Martin
