General Product Description
The ID30C-8, ID30C-16 and ID30CT are heavy-duty
compression drivers for use in medium-power public address
installations.
The drivers employ rugged phenolic diaphragms, 1.5-inch
diameter voice coils and “rim centered” ferrite magnet
structures for long life and reliability under extreme operating
conditions.
A hinged cycolac rear housing for easy access and
connection to a sound system, via a BX conduit connector,
is provided together with a plug-in, field-replaceable
diaphragm assembly.
The transformer model (ID30CT) includes connections for
25-V and 70-V distributed systems and a screwdriver
operated power-tap select switch.
The exterior parts are injection-molded from polycarbonate,
and all metal parts have been tropicalized for resistance to
high humidity and fungus.
Ideal for both indoor and outdoor applications, these drivers
are well suited for any installation requiring rugged,
medium-power performance.
Architects’ and Engineers’ Specifications
The loudspeaker(s) shall be of the compression-driver type
utilizing
high-temperature rated, 1.5-in. diameter voice coil.
The loudspeaker(s) shall exhibit essentially flat power
response from 300 to 4,000 Hz with a smoothly rolled-off
response beyond. Their sensitivity, when mounted on a PH
horn, will be 107 dB (1 W/1 m) with a 500- to 5,000-Hz
pink-noise signal applied.
