A wide bandwidth, high power-handling and high sensitivity 5" blind mount ceiling speaker built around CMS 3.0 – the third generation of Tannoy’s revolutionary Ceiling Monitor System technology. The CMS 503DC BM also features extra clamp extension to accommodate thicker ceiling panels, and a locking design that prevents inadvertent over-screwing. Magnetic grille attachment enables easy removal and fitting for custom painting and tapping changes with grilles now available as either traditional style (inset in bezel) or new Arco™ style which conceals the entire unit for more architectfriendly aesthetic appeal.

The CMS 503DC BM is supplied with an integral zinc plated steel back-can, ready to install as a single unit and feature an integrated, recessed termination box. The removable locking connector has screw terminals for secure wire termination and loop-thru facility. Strain relief is provided by a clamping mechanism for use with plenum-rated cable or conduit, while new spring-loaded and self-aligning clamps make for even quicker and easier installation. All models are supplied with classic grille, two tile support rails and one C-ring; Arco grille and plaster (mud) ring are available as optional accessories.
