CMS 3.0 CMS 803DC Q

The CMS 803DC Q is a full bandwidth 360-Watt high sensitivity loudspeaker that utilises our third generation Ceiling Monitor System technology (CMS 3.0). The “Q” variant of CMS 803DC is specifically designed for high-ceiling applications, incorporating an extended waveguide design with a tight, uniform 70-degree conical dispersion pattern. 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 Q delivers more consistent broadband directivity with enhanced intelligibility – plus highly accurate and linear response.

Optimised for Installation

Specifically designed with a 5 way self-aligning clamp system for fast, simple and cost effective installation, CMS 803DC Q 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 Q is finished in semi matt white and optimised for use with LAB GRUPPEN LUCIA amplifiers, which accommodate up to 8 CMS Series loudspeakers per channel.
