ARCHITECTURAL SPECIFICATIONS
The three-way full range loudspeaker systems shall incorpo-
rate 2x 15-in LF transducers, 2x 10-in cone MF transducers
and 2x 2-in exit compression driver HF transducer.
The LF drivers shall be separated by a “tuned” distance that
uses the Tuned Dipolar Array effect to achieve optimal low
frequency pattern control. Each MF driver shall be loaded
into a midrange horn constructed of 3mm birch plywood re-
inforced with high density polyurethane foam. The MF horn
shall incorporate a phase/displacement plug. Each HF driver
shall be loaded on a constant directivity horn with a nomi-
nal coverage pattern of 60
°
(h) x30
°
(v).
System frequency response shall vary no more than
±
3 dB
from 50 Hz to 17 kHz measured on axis. The low frequency
section shall produce a Sound Pressure Level (SPL) of 102 dB
SPL on axis at 1 meter with a power input of 1 Watt, and
shall be capable of producing a peak output of 141 SPL on
axis at 1 meter. It shall handle 2000 Watts of amplifier power
(AES Standard) and shall have a nominal impedance of 4
Ohms. The midrange frequency section shall produce a Sound
Pressure Level (SPL) of 112 dB SPL on axis at 1 meter with a
power input of 1 Watt, and shall be capable of producing a
peak output of 147 SPL on axis at 1 meter. It shall handle
800 Watts of amplifier power (AES Standard) and shall have
a nominal impedance of 4 Ohms. The high frequency section
shall produce a Sound Pressure Level (SPL) of 115 dB SPL on
axis at 1 meter with a power input of 1 Watt, and shall be
capable of producing a peak output of 147 SPL on axis at 1
meter. It shall handle 400 Watts of amplifier power (AES
Standard) and shall have a nominal impedance of 5 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. It shall be finished in black catalyzed poly-
urethane. Input connectors shall be one each male and fe-
male AP6. The enclosure shall include oval steel tubing (one
tube on each side) that accepts steel linking plates. The
plates shall attach to the steel tubing with quick-release
pins which shall be included. Sufficient precisely aligned pin
holes shall be placed in the steel tubing and linking plates
to allow for a variety of arraying angles and spacing. The
front of the loudspeaker shall be covered with a vinyl coated
perforated steel grill backed with open cell foam to protect
against dust.
The three-way full range loudspeaker shall be the EAW model
KF860.
