CMS 503DC
The Tannoy CMS 503DC is a full 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 on an all-new evolution of Tannoy’s proprietary Dual Concentric point-source driver, the CMS 503DC has been fundamentally re-engineered to deliver wider and more consistent broadband directivity, even greater intelligibility, and a more accurate and linear response.
