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.
