Description
The Tannoy CMS501 DC is a full bandwidth; high power and high sensitivity ceiling monitor system. The 130mm (5.00″) Tannoy Dual Concentric™ is a point source, constant directivity drive unit design comprising a multi fiber paper pulp mid bass cone and a 19mm (0.75″) ferrofluid cooled, titanium dome HF unit with neodymium magnet system. The driver and passive frequency dividing network is mounted in a vented, injection moulded, paintable front baffle manufactured from UV/weather resistant UL94V-0 ABS material.

The mid-bass and tweeter sections of the Tannoy Dual Concentric™ constant directivity driver are coincidentally aligned to a true point source; ensuring a wide and controlled dispersion for optimum coverage; this while avoiding the massive loss of energy, in the vertical plane at the crossover frequency, inherent in two-way discreet designs. This high power and high sensitivity design, with extended frequency response and very low distortion, is equipped with dynamic high frequency protection.

This compact unit is specifically designed for applications requiring the combination of premium sonic quality for music and speech reinforcement and exceptional reliability and intelligibility.
