ARCHITECTURAL SPECIFICATIONS
The sub bass loudspeaker systems shall incorporate 2x 15-in
LF transducers mounted in separate vented subenclosures
tuned for optimum low frequency response.
System frequency response shall vary no more than ±3 dB
from 40 Hz to 2100 Hz measured on axis with appropriate
signal processing. 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 capable of producing a
peak output of 137 SPL on axis at 1 meter. The loudspeaker
shall handle 1000 Watts of amplifier power (AES Standard)
and shall have a nominal impedance of 4 Ohms.
The loudspeaker enclosure shall be trapezoidal in shape. It
shall be constructed of 15mm thickness void-free cross-grain-
laminated Baltic birch plywood and shall employ extensive
internal bracing. The enclosure shall include a pole mount
socket extending through to the bottom of the enclosure to
accept a 1 3/8-in mounting pole. It shall be finished in
black polyurethane. Recessed handles, optional rear mount-
