The Soundtube 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.
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)
