The Tannoy CMS 503ICT BM is a professional 5-inch full-range ceiling loudspeaker designed for commercial and installed audio applications. Featuring Tannoy’s ICT (Inductive Coupling Technology) point-source driver, it delivers clear, natural sound with high speech intelligibility and accurate music reproduction for distributed audio systems.

The blind-mount (BM) design allows the back-can enclosure to be installed during construction, with the speaker assembly added later. This ensures a clean, seamless integration into ceilings while protecting the internal components during building work or renovations.
The CMS 503ICT BM supports 70V / 100V line distributed audio systems as well as 16-ohm low-impedance operation, providing maximum flexibility for multi-zone commercial installations. A front-accessible low-loss transformer tap selector allows installers to quickly adjust power levels without removing the speaker from the ceiling.
Constructed from durable ABS back-can and powder-coated steel grille, this speaker is engineered for long-term reliability in professional environments such as offices, hotels, retail stores, restaurants, and conference facilities. Its wide dispersion pattern ensures even sound coverage across the listening area, making it ideal for background music, paging, and multi-zone audio applications.
