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 fibre 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.
