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

ideal for music & paging applications in

retail, grocery stores, restaurants, hotels,

casinos, museums, trade shows & confer-

ence rooms. For applications where addi-

tional bass is required, SoundTube’s RS801i

8” subwoofer provides bass down to 40 Hz.
