The Tannoy CMS603ICT-LS is a professional 6-inch, full-range ceiling loudspeaker featuring Tannoy's proprietary ICT (Inductively Coupled Technology) driver, specifically engineered for blind-mount installation in commercial distributed audio systems. The ICT driver design eliminates the traditional voice coil and former, using an inductive coupling method to drive the cone. This results in significantly lower mechanical noise, reduced distortion, and exceptional long-term reliability, making it ideal for 24/7 operation in demanding environments such as hotels, retail stores, airports, and healthcare facilities. The speaker is designed for direct connection to 70V/100V constant voltage amplifiers, simplifying the installation of multiple speakers across large zones with long cable runs.

This model is configured for "blind mount" installation, meaning it is designed to be installed entirely from the front side of the ceiling without requiring access to the plenum space above. This is achieved through a unique mounting system where the speaker chassis is secured to the ceiling tile or drywall via rotating clamps that engage the backside of the surface. This feature dramatically reduces installation time and complexity, especially in retrofit situations or when dealing with difficult-to-access plenums. The speaker includes a paintable, magnetic grille for a clean, finished appearance that blends seamlessly into the ceiling.

The CMS603ICT-LS delivers clear, intelligible audio for background music and voice paging applications. Its full-range driver provides a balanced frequency response suitable for a wide variety of program material. The combination of robust ICT driver technology, convenient blind-mount design, and compatibility with constant voltage systems makes this loudspeaker a highly practical and reliable solution for integrators designing high-performance, low-maintenance commercial sound systems.
