SoundTube Entertainment SM400I Overview

The white SM400i 4” Surface-Mount Speaker from SoundTube Entertainment is a coaxial, ported speaker with a low-profile surface-mount enclosure design for indoor/outdoor applications. The proprietary BroadBeam waveguide technology incorporates a high-frequency waveguide mated to a 1” convex aluminum tweeter. It helps deliver a consistent dispersion pattern across the upper registers of the frequency spectrum.

This speaker features a corrosion-resistant Stealth U-bracket for easy and secure installation. The bracket utilizes one way fasteners for tool-free, theft-resistant security. The SM400i Speaker incorporates a five-position tap switch with transformer bypass position. Included port plugs can be used for added weather resistance. It delivers high-quality music and messaging for indoor and outdoor background to mid-level SPL applications. This surface-mount speaker is suitable for use in retail shops, grocery stores, restaurants, hotels, casinos, museums, trade shows, and conference rooms.
