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.
