  CMS 3.0 CMS 503ICT PI

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

  

  Optimised for Installation

  Specifically designed with a self-aligning 3 way clamp system for fast, simple and cost effective installation, CMS 503ICT PI also features extra clamp extension to accommodate thicker ceiling panels, and a locking design that prevents over-tightening. 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, back can, and plaster (mud) ring are available separately.

  

  LAB GRUPPEN Ready

  The CMS 503DC PI 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.
