Tannoy CMS-403ICT-E 4" 2-Way ICT Ceiling Speaker 70V/100V, Blind Mount

Incorporating a newly refined version of Tannoy’s proprietary ICT point-source driver, the CMS 403ICTe has been re-engineered for optimum compatibility with Lab Gruppen commercial amplifiers while also delivering consistent broadband directivity, precise articulation for voice and music, and exceptional long-term reliability.

The point source configuration of the Tannoy ICT driver’s mid-bass and tweeter sections ensures a wide and controlled dispersion for optimum coverage, avoiding significant energy losses in the vertical plane at the crossover frequency, a flaw inherent in typical two-way designs. The ICT (Inductive Coupling Technology) drive unit also addresses two common component failures in background music systems: the tweeter and the crossover. Use of wireless electromagnetic coupling to drive the tweeter means that no crossover is required, making the ICT drive unit exceptionally reliable and ideal for applications where constant heavy usage is the norm. The mineral-loaded polypropylene cone material and nitrile rubber surround further enhance durability and long-term reliability.

Specifically designed for fast, simple and cost effective installation in new and existing buildings, the CMS 403ICTe features a self-aligning clamp system. The “eyeball” design allows the driver to be entirely angled towards the listener within the fixed ceiling-mounting ring.

The CMS 403ICTe utilizes a 16 ohm driver, making it ideal for use in high performance low-impedance systems (with optimized performance when used in conjunction with Lab.gruppen LUCIA amplifiers). A low-insertion loss 30 W transformer is included, with convenient front switching for taps at 30 W, 15 W and 7.5 W, with an additional 3.75 W tap for traditional constant voltage systems.

The CMS 403ICTe is supplied with an integral back-can, ready to install as a single unit. The removable locking connector has screw terminals for secure wire termination and loop-thru facility. All models are supplied with two tile support rails and one C-ring; a plaster mud ring is available as an optional accessory.
