Tannoy CMS 803DC BM

The CMS 803DC BM is a full bandwidth 360-Watt high sensitivity loudspeaker that utilizes our third generation Ceiling Monitor System technology (CMS 3.0). Thanks to an all-new proprietary 8″ Dual Concentric point source driver with Omnimagnet technology on a Torus Ogive Waveguide, the UL certified CMS 803DC BM delivers wide and consistent broadband directivity with enhanced intelligibility – plus highly accurate and linear response.

Optimized for Installation

Specifically designed with a 5 way self-aligning clamp system for fast, simple and cost effective installation, CMS 803DC BM features an acoustically enhanced zinc plated steel back can and a removable locking screw terminal connector with loop-thru functionality. A low insertion loss 60 W transformer with convenient front panel tap switching, paintable powder coated steel mesh grille with dust protection, two tile support rails and one C-ring are all included. An Arco style grille, which conceals the entire unit for aesthetic purposes and plaster (mud) ring are available separately.
