Owner's Manual

Architectural Specifications
The loudspeaker shall consist of a 133 mm (5.25”) low-frequency
transducer and a 25.4 mm (1”) high-frequency transducer with a frequency
dividing network installed in a vented enclosure. The low-frequency voice
coil diameter shall be 25.4 mm (1”). The high-frequency transducer shall be
constructed of silk material with a proprietary BroadBeam Ring
™
waveguide.
Performance specications of a typical production unit shall be as follows:
Usable frequency response shall extend from 62 Hz - 22 kHz (±10 dB, half
space, independently veried). Measured sensitivity (2.83 V input, 1 meter)
shall be at least 83 dB. The speaker shall have a nominal impedance of 8
Ω and be available for 25, 70.7, and 100 V modes with transformer bypass.
The frequency dividing network shall have a crossover frequency of 3.5
kHz with slopes of 12 dB per octave (2nd order) for both low and high pass
lters. Rated power capacity shall be at least 50 W continuous (RMS) and
conform to EIA-426-B testing. Maximum continuous output at 1 M shall be
100 dB.
Installation and safety attachment for the speaker shall be by stainless
steel U-bracket afxed to the speaker chassis with steel insert. For safety
redundancy, a secondary cable shall be included and attached to the
speaker chassis.
The external wiring input connector shall be via 4-position ceramic terminal
strip, accepting up to 8-gauge wire. The system shall be for indoor/outdoor
applications and shall include a weather-resistant cover over all wire
connections.
The enclosure shall be constructed of injection-molded, High Impact
Polystyrene (HIPS). The grille shall be constructed of powder-coated
aluminum for lasting performance. Overall cabinet dimensions shall be no
more than 301.8 mm (11.88”) in height by 190.5 mm (7.5”) in width by
168.4 mm (6.63”) in depth (without SM bracket). The unit shall include port
plug, Allen wrench and watertight strain-relief bushing.
The speaker shall carry an ingress protection rating of IP65.
The system shall be the SoundTube SM52-EZ-WX for both low and high
impedance applications.

warranty on all electronics.
Applications
Designed for damp outdoor background to mid-level SPL surface-mount
applications. The system includes a detachable mounting bracket designed
for premounting in surface-mounting applications. The full-frequency
dispersion pattern and high sensitivity make the SM52-EZ-WX surface-
mount speaker ideal for music and paging in retail, amusement, restaurant,
airports, hotels, schools, and casinos. For applications where addition bass is
required, SoundTube’s RS1001i-II-T provides bass down to 41 Hz (±10 dB).
Patented Technologies
SoundTube Entertainment and the MSE Audio Group constantly develop
new technologies which enhance audio product performance. SoundTube
Entertainment innovations are protected by multiple U.S. and international
patents, which explicitly cover SoundTube dome, enclosure and dispersion
technologies. The MSE Audio Group actively defends its patents in order to
protect SoundTube resellers and end-users.
