ARCHITECTURAL SPECIFICATIONS
The two-way mid/high loudspeaker system shall incorporate
a 10-in cone MF transducer and a 2-in exit compression driver
HF transducer.
The MF driver shall be loaded into a midrange horn con-
structed of 3mm birch plywood reinforced with high density
polyurethane foam. The MF horn shall incorporate a phase/
displacement plug. The HF driver shall be loaded on con-
stant directivity horn with a nominal coverage pattern of
60
°
(h) x 45
°
(v). An internal passive filter network shall
provide system equalization.
System frequency response shall vary no more than
±
3 dB
from 200 Hz to 19 kHz measured on axis. The midrange fre-
quency section 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. 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
midrange frequency section shall handle 400 Watts of ampli-
fier power (AES Standard) and shall have a nominal imped-
ance of 8 Ohms. The high frequency section shall handle 200
Watts of amplifier power (AES Standard) and shall have a
nominal impedance of 10 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 4-terminal barrier strip
and dual Neutrik NL4 Speakon. A total of sixteen 3/8"-16
