Description

The CMS 503DC PI 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 PI delivers wide and consistent broadband directivity with enhanced intelligibility – plus highly accurate and linear response.
