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,
EASE
™
documented). 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
SpeedClamp
™
self-locking wire grip for
fast, easy & secure installation.
