ARCHITECTURAL SPECIFICATIONS
The two-way full range loudspeaker systems shall incorpo-
rate a 12-in LF transducer and a 1-in exit compression HF
transducer.
The LF driver shall be mounted in a vented enclosure tuned
for optimum low frequency response. The HF driver shall be
loaded on a constant directivity horn with a nominal cover-
age pattern of 90
°
(h) x 45
°
(v). 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 80 Hz to 18 kHz measured on axis. The loudspeaker
shall produce a Sound Pressure Level (SPL) of 99 dB SPL on
axis at 1 meter with a power input of 1 Watt, and shall be
capable of producing a peak output of 131.5 SPL on axis at
1 meter. The loudspeaker shall handle 450 Watts of amplifier
power (AES Standard) and shall have a nominal impedance
of 8 Ohms.
The loudspeaker enclosure shall be irregularly pentagonal in
shape and shall have rubber footpads on two sides allowing
its baffle to be angled up 45
°
or 15
°
. It shall be constructed
of 15mm thickness void-free cross-grain-laminated Baltic
birch plywood and shall employ extensive internal bracing.
It shall be finished in black catalyzed polyurethane. Input
connectors shall be dual Neutrik NL4 Speakon. A midrange
frequency attenuating presence control shall be provided.
Two 5/16”-18 threaded mounting/suspension points shall
be provided on top of the enclosure spaced to accept an
external Ultimate Brand standmount adapter. The front of
the loudspeaker shall be covered with a vinyl coated perfo-
rated steel grill backed with open cell foam to protect against
dust.
The two-way full range loudspeaker shall be the EAW model
SM122e.
