terminal for 8 Ohm or distributed systems
and shall accept from 10 – 22 gauge wire.
The grille shall be constructed of pow-
der-coated steel for lasting performance
and attach via pressure fit directly to the
ABS baffle.
The system shall be the SoundTube
IW500i with mounting hardware for both
low & high impedance applications.

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
to an infinite baffle. The low-frequency
transducer shall have a polypropylene cone
with a butyl rubber surround. The high-fre-
quency transducer shall be constructed of
aluminum with a proprietary 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 55
Hz – 22 kHz (-10 dB, half space, no exter-
nal equalization). Measured sensitivity
(2.83 Volt, 1 meter) shall be at least 88 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 coil/8
Ohm direct. The frequency-dividing net-
work shall have a crossover 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 con-
form to EIA-426-B testing. Maximum con-
tinuous output at 1 meter shall be 107 dB.
Installation for the IW500i shall be by
4-screw, optimally engineered constant-
tension mounting assembly. The external
wiring input connector shall be a spring

Technical Data and
Specification Tools
Technical Data
SoundTube Entertainment strives to
provide complete and effective techni-
cal information and data to dealers,
engineers and designers. All data are
available from SoundTube Entertain-
ment or at www.soundtube.com and
includes EASE™ Data – 3-D polar plots
and SoundTubeSPEC™ – Proprietary
SoundTube speaker placement software.
Independent Data Acquisition &
Verification
All data for SoundTube speakers is inde-
pendently collected from and verified by
NWAA Labs (www.nwaalabs.com) using
their proprietary MACH testing system.
All data is collected and analysed accord-
ing 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 includ-
ing EASE 4.x, GLL and CLF.
