coil/8 Ohm direct. The frequency-
dividing network shall have a cross-
over frequency of 3 kHz with slopes
of 12 dB per octave (second order) for
both low and high-pass filters. Rated
power capacity shall be at least 75
Watts continuous power (RMS) and
conform to EIA-426-B testing. Maxi-
mum continuous output at 1 meter
shall be 106.5 dB.
Installation for the IW500b shall be
by 4-screw, constant-tension optimally
engineered mounting assembly. The
external wiring input connector shall
be by hard wired leads for 8 Ohm or
distributed systems.
The grille shall be constructed of
powder-coated steel for lasting per-
formance and attach via pressure fit
directly to the ABS bezel. The backcan
shall be constructed of drawn steel.
The system shall be the SoundTube
IW500b with mounting hardware for
both low & high impedance applica-
tions.

testing system. All data is collected and
analysed according to ASTM, ISO and
AES standards using EASERA, TEF and
MLSSA. Full balloon data including both
phase and magnitude is compiled into
a variety of formats including EASE 4.x,
GLL and CLF.
Architectural Specifications
The loudspeaker shall consist of
a 133 mm (5.25 in) low-frequency
transducer and a 25 mm (1 in) high-
frequency transducer with a frequency-
dividing network installed in a sealed
enclosure. The low-frequency trans-
ducer shall have a polypropylene cone
with a butyl rubber surround. The
high-frequency transducer shall be
constructed of aluminum with a pro-
prietary BroadBeam® waveguide.
The low-frequency voice coil diameter
shall be 25.4 mm (1 in).
Performance specifications of a
typical production unit shall be as
follows: Useable frequency response
shall extend from 69 Hz – 22 kHz (-10
dB, half space, no external equaliza-
tion). Measured sensitivity (2.83 Volt,
1 meter) shall be at least 87.5 dB. The
speaker shall have a nominal imped-
ance of 8 Ohms and shall be available
for 25/70.7/100 Volt modes with voice
