The CMS 503DC LP is a full bandwidth 240-Watt high sensitivity loudspeaker that utilizes 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.
Optimized 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.
