The CMS 503ICT LP is a full 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 LP delivers consistent broadband directivity with enhanced intelligibility. ICT drivers provide exceptional long-term reliability – and are ideal for constant-usage applications.
