Tannoy CMS 503DC PI 5" Full Range Ceiling Loudspeaker with Dual Concentric Driver (Pre-Install,Pair) - TA-CMS503DC-PI

Product Overview

The Tannoy CMS 503DC PI is a pre-install 5-inch dual concentric ceiling loudspeaker for high-intelligibility speech and program audio in commercial interiors. Sold as a pair without a back can for first-fix wiring, it uses Tannoy's third-generation CMS 3.0 point-source driver to deliver wide, consistent directivity from a discreet ceiling footprint. UL 2043 certification for air-handling spaces and 70V/100V transformer taps make this dual concentric ceiling speaker well suited to plenum and distributed-audio installations.

Product Description

The CMS 503DC PI is a full-bandwidth, high-sensitivity loudspeaker built around a 5-inch Dual Concentric point-source driver with Omnimagnet technology on a Torus Ogive waveguide, delivering wide, even broadband directivity with the linear, accurate response Tannoy is known for. It handles 60 watts continuous and 240 watts peak, suiting distributed speech and background-music systems where intelligibility is critical. As the pre-install (PI) version, it ships without a back can, allowing first-fix mounting and cabling ahead of final fit-out; a back can is available separately. The system is UL 1480 certified for general signalling systems and UL 2043 certified for air-handling (plenum) spaces, supporting code-compliant installation in commercial ceilings. Multiple 70V and 100V transformer taps support distributed line operation, a 16-ohm direct input is available for low-impedance use, and the speaker is optimised for Lab Gruppen LUCIA amplifiers running up to eight CMS-series loudspeakers per channel. A self-aligning three-way clamp system with included C-ring and tile rails speeds installation, and the removable magnetic grille can be custom painted; optional ARCO designer grilles are available for minimal architectural impact. This ceiling loudspeaker is part of the wider Tannoy commercial loudspeaker collection; for a larger full-range ceiling option, compare the Tannoy CMS 1201DC.
