CMS 503ICT
The Tannoy CMS 503ICT is a wide bandwidth, high power-handling and high sensitivity loudspeaker built around CMS 3.0 – the third generation of Tannoy’s revolutionary Ceiling Monitor System technology. Incorporating a newly refined version of Tannoy’s proprietary ICT™ point-source driver, the CMS 503ICT has been re-engineered for optimum compatibility with Lab.gruppen commercial amplifiers while also delivering consistent broadband directivity, precise articulation for voice and music, and exceptional long-term reliability.… Read More
