SoundTube - CM400i - 4" Coaxial In-Ceiling Speaker (Single)

SoundTube - CM400i - 4" Coaxial In-Ceiling Speaker (Single)

The CM400i is a four-inch, two-way, blindmount in-ceiling speaker that delivers effective low-end response (75 Hz, -10 dB) and optimal off-axis performance (2 to 10 kHz, independently verified). The CM400i speaker design incorporates a low-profile grille and fiveposition tap switch with a transformer bypass position. Mounting hardware is included and features a fast and secure constant-tension fixed-wing mounting system.

This product has one 4.0 inch polypropylene woofer and one 1.0 inch convex aluminum tweeter with FerroFluid cooling. The CM400i features a rapid installation blind-mount, fixed- wing mounting mechanism with constant tension design affixing to ceiling thicknesses ranging from 0.025 inch (0.6 mm) to 1.87 inch (47.5 mm). It also has an easy access five-position selectable tap switch for 25-, 70.7- and 100-volt applications with transformer bypass position.

The CM400i also comes with a separate tool-free magnetic grille and bezel assembly for ease of install and in-field painting with a powder-coated steel grille for lasting durability. The 90 dB average sensitivity offers high-output capabilities and reduced amplification costs. UL 1480 (UEAY) and 2043 approved. Included accessories: Color-coded (orange) tile bridge, paint mask, Euroblock connector and UL cover plate.

It is designed for in-ceiling background to mid-level SPL applications, the CM400i is ideal for music and paging in courthouses, schools, retail stores, grocery, restaurants, hospitals, hotels, casinos, museums, conference rooms and churches. For applications where additional bass is required, SoundTube’s CM1001d-T or SM1001p 10-inch subwoofers provide additional low-end response down to 41 Hz (-10 dB).
