Product description
The Tannoy CMS 503ICT PI is a wide bandwidth, high power-handling and high sensitivity loudspeaker built around CMS 3.0 – the third generation of Tannoy’s revolutionary Ceiling Monitor System technology. Incorporating a newly refined version of Tannoy’s proprietary ICT™ point-source driver, the CMS 503ICT PI 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 the significant energy losses in the vertical plane at the crossover frequency that are 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.
The CMS 503ICT PI utilizes a 16 ohm driver, making it ideal for use in high performance lowimpedance systems (with optimized performance when used in conjunction with Lab.gruppen LUCIA amplifiers). The low-insertion loss 30 W transformer features convenient front bezel 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 503ICT PI also features extra clamp extension to accommodate thicker ceiling panels, and a locking design that prevents inadvertent over-screwing. Magnetic grille attachment enables easy removal and fitting for custom painting and tapping changes with grilles now available as either traditional style (inset in bezel) or new Arco™ style, which conceals the entire unit for architect-friendly aesthetic appeal.
The CMS 503ICT PI is supplied without a back-can. All models are supplied with classic grille, two tile support rails and one C-ring; Arco grille back-can and plaster (mud) ring are available as optional accessories.
