EXP 3/19/97 SHB
The two-way loudspeaker systems shall incorporate a 10-in
cone MF transducer and 2x 2-in exit compression driver HF
transducers.
The MF driver shall be loaded into a vertically asymetrical
midrange horn constructed of 1/8-in birch plywood reinforced
with high density polyurethane foam. The MF horn’s asym-
metrical shape shall direct MF energy down at a nominal angle
of 10°. The MF horn shall incorporate a phase/displacement
plug.
Each HF driver shall be loaded on a constant directivity horn
with a combined nominal coverage pattern of 55° (h) x 40°
(v). The two HF horns shall abut vertically. The upper HF horn
shall be angled down 10°. The lower HF horn shall be angled
down 45°. An internal passive filter network shall provide sys-
tem equalization and frequency shading creating optimal
integration between the two HF horns.
The system shall include a switch allowing the two HF drivers
to be powered in parallel or separately. An control shall be
provided allowing the lower HF driver to be attenuated when
the two drivers are powered in parallel.
System frequency response shall vary no more than ±3 dB from
200 Hz to 17 kHz measured on axis. The mid frequency sec-
tion shall produce a Sound Pressure Level (SPL) of 109 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 400 Watts of amplifier power (AES
Standard) and shall have a nominal impedance of 8 Ohms. The
high 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
141 SPL on axis at 1 meter. The HF section shall handle 200
Watts of amplifier power (AES Standard) and shall have a
nominal impedance of 7 Ohms when the section is powered in
parallel.
The loudspeaker enclosure shall be trapezoidal in shape. It
shall be constructed of 1/2-in 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 three each male and
female AP6 (M/F for parallel HF section, dual M/F for sepa-
rately powered HF sections). Two 19-in flytracks shall be
installed on the top of the enclosure. The front of the loud-
speaker shall be covered with a vinyl coated perforated steel
grille backed with open cell foam to protect against dust.
The two-way mid/high loudspeaker shall be the EAW model
KF855.
