A & E SPECIFICATIONS
The 2-way full range ceiling mounted coaxial loudspeaker
systems shall incorporate 6x 5.25-in concentrically arrayed
LF transducers plus 2x 5.25-in phase aligned LF transducers
and a 1-in exit compression driver HF transducer.
The LF drivers shall be mounted in a vented enclosure tuned
for optimum low frequency response. The HF driver shall be
loaded on an axis symmetrical constant directivity horn with
a nominal coverage pattern of 60
°
(conical). An internal
passive filter network shall provide fourth order acoustical
crossover and system equalization.
System frequency response shall vary no more than
±
3 dB
from 75Hz to 18kHz measured on axis. The loudspeaker shall
produce a Sound Pressure Level (SPL) of 101 dB SPL on axis
at 1 meter with a power input of 1 Watt, and shall be ca-
pable of producing a peak output of 131.8 SPL on axis at 1
meter. The loudspeaker shall handle 300 of amplifier power
(AES Standard) and shall have a nominal impedance of 4
Ohms.
The loudspeaker enclosure shall be rectangular in shape and
shall be designed to mount in a 24-in ceiling grid. It shall be
constructed of 1/2-in thickness void-free cross-grain-lami-
nated Baltic birch plywood. It shall be finished in black cata-
lyzed polyurethane. Input connectors shall be 2-terminal
barrier strip type. A total of eight 3/8"-16 threaded mount-
ing points (2 each right and left side, 4 on back) shall be
provided. The front of the loudspeaker shall be covered with
a vinyl coated perforated steel grille.
The 2-way full range ceiling mounted coaxial loudspeaker
shall be the EAW model CP621.
