Description
The RS400 is a 4" coaxial, ported speaker
with an open-ceiling enclosure design.
Hanging hardware is included & fea-
tures a SpeedClamp self-locking wire
™
grip for fast, easy & secure installation.
SoundTube's custom-engineered driver
and electro-acoustic network delivers
high-performance sound in a cost-effective
speaker design. The RS400i speaker incorpo-
rates a low-profile grille and a 5-position tap
switch with voice coil/4 Ohm direct.
Applications
Designed for indoor & outdoor back-
ground to mid-level SPL applications, the
RS400i includes a single-point mounting
system for rapid open-ceiling installations.
Cost-effective engineering with high-per-
formance sound makes the RS400i speaker
