The CMS 603ICT LS is a wide bandwidth 240-Watt high sensitivity loudspeaker that utilises our third generation Ceiling Monitor System technology (CMS 3.0), and is UL certified for use with non-DC supervised systems. Thanks to an all-new proprietary 6″ ICT (Inductive Coupling Technology) point source driver with extended frequency range, the CMS 603ICT LS delivers consistent broadband directivity with enhanced intelligibility. ICT drivers provide exceptional long-term reliability – and are ideal for constant-usage applications.
