Overview
Optimize commercial audio, paging and security announcements with the SoundTube CM400I-BK 2-way in-ceiling speaker. Designed for integrators and facility managers, this speaker pairs a 4" polypropylene woofer with a BroadBeam convex aluminum tweeter to deliver intelligible speech and even coverage across retail, education, healthcare and security environments. With a wide frequency range (75 Hz–22 kHz) and a high 90 dB sensitivity, the CM400I-BK provides high output with less amplification — lowering equipment and operating costs.
Installers appreciate the rapid blind-mount, fixed-wing mounting mechanism that fits a range of ceiling thicknesses and a five-position tap switch supporting 25, 70.7 and 100V systems (plus transformer bypass) for flexible system design. The separate tool-free magnetic grille and powder-coated bezel make in-field painting and maintenance fast, while UL 1480 and 2043 approvals meet commercial safety requirements. Ideal for paging, background music, public address and security/surveillance monitoring applications, the CM400I-BK delivers reliable, professional audio performance. Specify the SoundTube CM400I-BK for efficient installs and clear, consistent coverage — request a quote or add to your next pro-audio project.
