Tannoy’s award-winning CMS 401DCe Ceiling Monitor System builds on the strengths and practicality of the CMS401e, incorporating Tannoy’s Dual Concentric driver technology for superior performance with music and speech reproduction. This point source, constant directivity drive unit comprises a 100mm (4.00") multi fibre paper pulp mid bass cone and a 19mm (0.75") ferrofluid cooled, titanium dome HF unit with neodymium magnet system. The WideBand high frequency unit in the Dual ensures that the CMS401DCe 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 Tannoy THP 30 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 80Hz-54kHz, continuous program power capacity of 120Watts and sensitivity of 88dB/Watt, the CMS 401e is perfect for smaller room installation that demand highly accurate, articulate and musical sound.

Specifically designed for fast, simple and cost effective installation in new and existing buildings, the CMS401e can be angled towards the listener. The driver and passive frequency-dividing network are mounted in an injection-moulded ABS pod that can be swivelled and tilted within the ceiling ring. The addresses the challenge of difficult speaker placement in less than perfect room configurations as the sound can be directed towards the desired area of cover.
