Tannoy CMS 403DCE 4" Full Range Directional Ceiling Loudspeaker with Dual Concentric Driver (Blind-Mount,Pair) - TA-CMS403DCE

Product Overview

The Tannoy CMS 403DCE is a directional 4-inch dual concentric ceiling loudspeaker designed for high-intelligibility speech and program audio in commercial interiors. Sold as a blind-mount pair, it uses Tannoy's third-generation CMS 3.0 point-source driver to deliver wide, consistent directivity from a discreet ceiling footprint. With an adjustable tilt and 360-degree rotation plus 70V/100V transformer taps, this dual concentric ceiling speaker aims sound precisely in boardrooms, atriums, and other architecturally sensitive spaces.

Product Description

At the heart of the CMS 403DCE is a 4-inch Dual Concentric point-source driver with Omnimagnet technology mounted on a Torus Ogive waveguide, an arrangement that produces wide, even broadband directivity and the linear response Tannoy is known for in studio monitoring. The full-bandwidth system handles 40 watts continuous and 160 watts peak, suiting distributed speech and background-music systems where intelligibility is critical. Its directional design with adjustable tilt and 360-degree rotation lets integrators aim coverage toward listeners even in difficult placements. Multiple 70V and 100V transformer taps support distributed line operation, with a 16-ohm direct input available for low-impedance use, and the system is optimised for Lab Gruppen LUCIA amplifiers running up to eight CMS-series loudspeakers per channel. The blind-mount enclosure ships with an integral moulded ABS back can as a single-unit assembly, and the self-aligning three-way clamp system with included C-ring and tile rails speeds installation. The semi matt white grille is removable for custom painting. This ceiling loudspeaker is part of the broader Tannoy commercial loudspeaker collection; for a wide-bandwidth ICT-driver alternative in the same form factor, compare the Tannoy CMS 403ICTE.
