CMS 3.0 CMS 503DC LP

The CMS 503DC LP is a full bandwidth 240-Watt high sensitivity loudspeaker that utilises our third generation Ceiling Monitor System technology (CMS 3.0). Thanks to an all-new proprietary 5" Dual Concentric point-source driver with Omnimagnet technology on a Torus Ogive Waveguide, the UL certified CMS 503DC LP delivers wide and consistent broadband directivity with enhanced intelligibility – plus highly accurate and linear response.

Optimised for Installation

Specifically designed with a 4 way self-aligning clamp system for fast, simple and cost effective installation, CMS 503DC LP features an ultra-shallow back can for applications where cavity space is limited, and a removable locking screw terminal connector with 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 503DC LP 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.
