The CMS 403ICTE is a wide bandwidth 160-Watt high sensitivity loudspeaker that utilises our third generation Ceiling Monitor System technology (CMS 3.0). Thanks to an all-new proprietary 4" ICT (Inductive Coupling Technology) point source driver with extended frequency range, the CMS 403ICTE delivers consistent broadband directivity with enhanced intelligibility. ICT drivers provide exceptional long-term reliability – and are ideal for constant-usage applications.

Adjustable Tilt Angle

Specifically designed with a self-aligning 3 way clamp system for fast, simple and cost effective installation, the CMS 403ICTE can be angled towards the listener within the fixed ceiling-mounting ring. By discreetly pivoting the loudspeaker towards the desired area of coverage, the challenge of speaker placement in a less than ideal room is easily overcome.

Optimised for Installation

Equipped with a low-insertion loss 30 W transformer with convenient front panel tap switching, CMS 403ICTE features an integral ABS back-can with removable locking screw terminal connector and loop-thru functionality. The paintable powder coated steel mesh grille with dust protection, two tile support rails and one C-ring are all included.


The CMS 403ICTE 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.
