ARCHITECTURAL SPECIFICATIONS
The low frequency loudspeaker systems shall incorporate 2x
15-in LF transducers.
The LF drivers shall be mounted in a low frequency horn
constructed of 3mm birch plywood reinforced with high den-
sity polyurethane foam for optimum low frequency response.
The system shall have a nominal coverage pattern of 150°
(h) x 150°(v).
System frequency response shall vary no more than ±3 dB 90
Hz to 300 Hz measured on axis. The loudspeaker shall pro-
duce a Sound Pressure Level (SPL) of 105 dB SPL on axis at
1 meter with a power input of 1 Watt, and shall be capable
of producing a peak output of 144 SPL on axis at 1 meter.
The loudspeaker shall handle 2000 Watts of amplifier power
(AES Standard) and shall have a nominal impedance of 4
Ohms.
The loudspeaker enclosure shall be trapeziodal in shape. 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 poly-
urethane. Input connectors shall be a 4-terminal barrier strip
plus one Neutrik NL4 Speakon. A total of eighteen 3/8”-16
threaded mounting/suspension points (5 on bottom, 4 each
top and sides, 1 back) shall be provided. The front of the
loudspeaker shall be covered with a vinyl coated perforated
steel grill.
The low frequency loudspeaker shall be the EAW model BH862.
