Tannoy’s CMS 501 DC Ceiling Monitor System builds on the strengths and practicality of the CMS 501, incorporating Tannoy’s Dual Concentric driver technology for superior performance with music and speech reproduction. This point source, constant directivity drive unit comprises a 130mm (5.00") multi fibre paper pulp mid bass cone and a 19 mm (0.75") ferrofluid cooled, titanium dome HF unit with neodymium magnet system. The WideBand high frequency unit in the Dual ensures that the CMS 501 DC delivers exceptionally detailed and open sound stage for unrivalled intelligibility. Extending the bandwidth gives percussive sounds more reality and impact, with vocals and instruments clearly more separate and distinct.
The inclusion of a premium quality 30W low insertion loss multi-tap transformer, for distributed-line operation, provides high system sensitivity, wide bandwidth and exceptional dynamic range. With a frequency range of 74Hz-54kHz, continuous program power capacity of 120Watts and sensitivity of 88dB/Watt, the CMS 501DC is perfect for medium sized room installation that demand highly accurate, articulate and musical sound.
The CMS 501DC is available as Blind Mount and Pre-Install variant without transformer, with or without an integrated zinc-plated steel back can, and includes features such as recessed termination box, removable locking connector with screw terminals and a strain relief clamp for use with plenum rated cable or conduit. Spring loaded self-aligning clamps make for quick and easy installation, while all models are supplied with two tile support rails and one C-ring.
