Overview
The CMS 503ICT BM is a wide bandwidth 200-Watt high sensitivity loudspeaker that utilises our third generation Ceiling Monitor System technology (CMS 3.0). Thanks to an all-new proprietary 5" ICT (Inductive Coupling Technology) point source driver with extended frequency range, the UL certified CMS 503ICT BM delivers consistent broadband directivity with enhanced intelligibility. ICT drivers provide exceptional long-term reliability – and are ideal for constant-usage applications.
Optimised for Installation
Specifically designed with a self-aligning 3 way clamp system for fast, simple and cost effective installation, CMS 503ICT BM features an acoustically enhanced zinc plated steel back can with removable locking screw terminal connector and loop-thru functionality. A low-insertion loss 30 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 503ICT BM 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.
