CMS 3.0 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 Omni magnet technology on a Torus Ogive Waveguide, the UL
certifi ed 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 matt white and optimized
for use with LAB GRUPPEN LUCIA amplifiers, which accommodate up to 8 CMS Series
loudspeakers per channel.
