RS500i
Open-Ceiling Speaker
Technical Information for System Engineers
Applications
Designed for indoor & outdoor back-
ground to mid-level SPL applications,
the RS500i includes a single-point
mounting system for rapid open-ceiling
installations. The 100° broad dispersion
pattern (55 Hz – 10 kHz) and high sensi-
tivity (88.5 dB 1W/1M) make the RS500i
speaker ideal for music & paging appli-
cations in retail, grocery stores, restau-
rants, hotels, casinos, museums, trade
shows & conference rooms. For applica-
tions where additional bass is required,
SoundTube’s RS801i 8” subwoofer pro-
vides 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
aluminum tweeter. The BroadBeam
®
high-frequency waveguide delivers a
consistent 100°
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.
