Tannoy CMS 803DC BM 8" Full Range Ceiling Speaker with Dual Concentric Driver for Installation Applications 360W
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.
LAB GRUPPEN Ready
The CMS 803DC BM is finished in semi-matte white and optimized for use with LAB GRUPPEN LUCIA amplifiers, which accommodate up to 8 CMS Series loudspeakers per channel.
