The CMS 603DC PI is a full bandwidth 320-Watt high sensitivity loudspeaker that utilizes our third generation Ceiling Monitor System technology (CMS 3.0). Thanks to an all-new proprietary 6" Dual Concentric point source driver with Omnimagnet technology on a Torus Ogive Waveguide, the UL certified CMS 603DC PI delivers wide and consistent broadband directivity with enhanced intelligibility – plus highly accurate and linear response.
Optimized for Installation
Specifically designed with a self-aligning 4-way clamp system for fast, simple and cost-effective installation, CMS 603DC PI also features extra clamp extension to accommodate thicker ceiling panels, and a locking design that prevents over-tightening. 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, a back can, and plaster (mud) ring are available separately.
LAB GRUPPEN Ready
The CMS 603DC PI is finished in semi-matte white and optimised for use with LAB GRUPPEN LUCIA amplifiers, which accommodate up to 8 CMS Series loudspeakers per channel.
