The CMS 503ICT LP 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. Based around the standard CMS 503ICT model, but with a greatly reduced back-can depth, the ultra low-profile CMS 503ICT LP has been engineered specifically for applications where ceiling cavity dimensions are a critical limiting factor.
This specialized ceiling device has all the sonic performance of the standard CMS 503ICT, in a much shallower profile package, achieving similar back-can volume by virtue of slightly larger diameter (and hole cut-out size). 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 CMS 503ICT LP 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 30W transformer features convenient front bezel switching for taps at 30W, 15W and 7. W, with an additional 3.75W tap for traditional constant voltage systems. The CMS 503ICT LP 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 LP is a blind mount loudspeaker device, supplied with an integral back-can, ready to install as a single unit. The shallow-profile zinc plated steel back-can has an integrated, recessed termination box. The removable locking connector has screw terminals for secure wire termination and loop-thru facility. Strain relief is provided by a clamping mechanism for use with plenum-rated cable or conduit, while new spring-loaded and self-aligning clamps make for even quicker and easier installation. CMS 503ICT LP is supplied with classic grille, two tile support rails and one C-ring; Arco grille and plaster (mud) ring are available as optional accessories.
