SoundTube Entertainment RS400I Overview

The white RS400i 4″ Coaxial Open-Ceiling Speaker from SoundTube Entertainment is a two-way ported speaker with an open-ceiling enclosure design that delivers effective low-end response (from 76 Hz to 22 kHz @ -10 dB). The BroadBeam technology in this speaker incorporates a high-frequency waveguide mated to a 1" convex titanium tweeter. The BroadBeam high-frequency waveguide delivers a consistent dispersion pattern across the operating bandwidth that offers optimum edge-to-edge coverage and reduced power needs.

The RS400i Speaker incorporates a low-profile grille and a five-position tap switch with transformer bypass position. It features a SpeedClamp self-locking cable grip for fast, easy, and secure installation. Designed for indoor and outdoor background to foreground SPL applications, the RS400i Speaker includes a single-point mounting system for rapid open-ceiling installations. The broad dispersion pattern of 125° and high sensitivity of 82.5 dB 1W/1m makes this speaker suitable for retail, restaurants, grocery stores, hotels, casinos, fitness centers, conference rooms, big box stores, museums, trade shows, airports, and other open-ceiling applications.
