The Tannoy CMS 503ICT PI is a compact 5-inch full-range ceiling loudspeaker engineered for professional installation in commercial and public audio environments. Designed for reliability and consistent performance, it features Tannoy’s ICT (Inductive Coupling Technology) point-source driver, delivering extended frequency response and clear sound reproduction for music and voice applications.
This ceiling speaker is part of the Tannoy CMS (Ceiling Monitor System) series and is optimized for background music, paging systems, and distributed audio installations in environments such as hotels, airports, retail stores, offices, restaurants, and conference rooms.
The CMS 503ICT PI supports both low-impedance (16-ohm) operation and 70V/100V line systems, making it suitable for large multi-zone installations. It includes a low-insertion-loss transformer with front-accessible tap switching, allowing installers to easily configure power levels for distributed audio systems.
Its durable construction includes a steel grille, ABS baffle, and high-quality mineral-loaded polypropylene driver, ensuring long-term reliability even in demanding commercial environments. The pre-install (PI) version allows integrators to install the back-can and wiring during construction while fitting the speaker assembly later.
