Description  
The RS500i is a 5.25” 2-way ported  
speaker with an open-ceiling enclosure  
design that delivers effective low-end  
response (55 Hz) and optimal off-axis per-  
formance (105° dispersion up to 10 kHz,  
EASEdocumented). SoundTube’s pro-  
prietary BroadBeam® waveguide tweeter  
system delivers consistent high-perfor-  
mance audio coverage across the operating  
bandwidth. The RS500i speaker design  
incorporates a low-profile grille, propri-  
etary M5 motor-board and a 6-position  
tap switch with voice coil/8 Ohm direct.  
Hanging hardware is included & features  
SpeedClampself-locking wire grip for  
fast, easy & secure installation.

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.

Architectural Specifications  
The loudspeaker shall consist of a 133  
mm (5.25 in) low-frequency transducer  
and a 25 mm (1.0 in) high-frequency trans-  
ducer with a crossover installed in the  
ported enclosure. The low-frequency voice  
coil diameter shall be 25 mm (1.0 in).

Specification Tools  
BroadBeam® Wide  
Dispersion Technology  
Technical Data  
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, EASEdocu-  
mented). The result is an audio system  
with fewer speakers, reduced power  
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-  
Performance specifications of a typi-  
cal production unit shall be as follows:  
Useable frequency response shall extend  
from 55 Hz – 22 kHz (-10 dB, half space,  
no external equalization). Measured  
sensitivity (2.83 Volt input, 1 meter) shall  
be at least 88.5 dB. The speaker shall  
have a nominal impedance of 8 Ohms  
and be available for 25, 70.7 & 100 Volt

crossover frequency of 3 kHz with slopes  
of 12 dB per octave (2nd order) for both  
low & high pass filters. Rated power  
capacity shall be at least 75 Watts continu-  
ous power (RMS) and conform to EIA-426-  
B testing. Maximum continuous output at
