SM500i
Surface-Mount Speaker
Technical Information for System Engineers
proprietary captured ball mount-
ing system with security screw for
theft prevention. The full frequency
dispersion pattern (45 Hz – 10 kHz,
EASE
™
documented) and high sensitiv-
ity (88.5 dB 1W/1M) make the SM500i
surface-mount speaker ideal for music
& paging in retail, amusement, restau-
rant, airports, hotels, schools and casi-
nos. For applications where additional
bass is required, SoundTube’s RS801i
subwoofer provides bass down to 40 Hz.
BroadBeam
®
Wide
Dispersion Technology
More than 3 years in development,
SoundTube’s proprietary BroadBeam
®
technology incorporates a high-fre-
quency waveguide mated to a 1” convex
metal tweeter. BroadBeam
®
wave-
guide technology delivers a consistent
BroadBeam
®
dispersion pattern across
the upper registers of the frequency
spectrum (up to 10 kHz, EASE
™
docu-
mented). The result is an audio system
with fewer speakers, reduced power
needs, shorter installation time and cost
savings on shipping & labor.

Data Acquisition
All performance data acquired at
SoundTube’s Technical Measurement Cen-
ter (TMC) are analyzed using a variety
of standard measurement techniques,
including Measured Length Sequence
(MLS) and Time Delay Spectrometry
(TDS). Performance, development and
data acquisition tools include: Gold Line
TEF 20, CLIO, LMS, LEAP, and propri-
etary modeling software. EASE™ data
are acquired through an automated TEF
20/Outline/EASE
