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.

Stylish and affordable!
Color: Grey, Size: 4 Pack, Color: Grey, Size: 4 Pack
These shelves are rey stylish, light and durable! The set came with everything needed to install. The color is just as described. Price is steal and these shelves can definitely be used anywhere throughout the house. I did give it only 4 stars because as you can see in the photos, the underneath was not completely finished. Decided to keep because the price was unbeatable.
