ARCHITECT’S AND ENGINEER’S SPECIFICATIONS
The ceiling/wall mount loudspeaker shall be an integrated cone
driver, line transformer and baffle (grille) assembly. The driver shall
be an 8" diameter cone type with an 8 Ohm nominal impedance
and a 5.3 oz ferrite magnet. Power handling shall be 6 watts RMS
(15 watts program) with a frequency response from 90HZ - 16KHZ
and sensitivity of 96 dB SPL at 1 watt input measured at a distance
of 1 meter. The line transformer shall accept 25V and 70V inputs
with taps for 0.5W, 1W, 2W, 3W and 6W with an output
impedance of 8 Ohms with less than a 1.5 dB insertion loss. The
baffle shall be made of CRS with a white, corrosion resistant paint
finish. [A screwdriver adjustable, noise free volume control shall
be mounted in the center of the baffle easily accessible for
adjustment when the assembly is installed. The volume control
shall withstand heat, fumes and other airborne contaminants].
The baffle shall be 13.4" O.D. with a 2.5" depth for the assembly
behind the baffle. Holes shall be provided in the baffle for
mounting to standard loudspeaker backboxes. Weight for the
assembly shall be 3.5 lb. The ceiling/wall mount loudspeaker shall
be the TOA PC-671R [PC-671RV].
