The Tannoy CMS503DC-BM is a professional 5-inch full-range ceiling loudspeaker designed for discreet, high-quality audio in commercial installations, featuring both Tannoy's Dual Concentric driver technology and a "Blind Mount" design. The Dual Concentric design places a high-frequency compression driver at the acoustic center of the bass/midrange cone, ensuring sound from both drivers originates from the same point. This results in exceptional phase coherence, precise stereo imaging, and a wide, uniform dispersion pattern. The "Blind Mount" feature means the speaker is installed above the ceiling tile or drywall, with only a flush, paintable grille visible from below, creating a completely invisible audio source that preserves the clean aesthetics of modern architectural spaces.

This loudspeaker is built with a rigid, fire-retardant enclosure designed to fit within standard ceiling plenums. It includes a built-in multi-tap transformer for easy integration into constant-voltage (70V/100V) distributed audio systems, allowing installers to select the appropriate power tap to match the speaker's output level to the acoustic requirements of the zone. This simplifies the design of large-scale sound systems. The combination of coaxial technology and blind-mount installation makes it ideal for high-end retail, corporate offices, luxury hospitality, and any environment where both superior sound quality and visual discretion are paramount. The speaker delivers clear, articulate audio for background music and speech reinforcement.

For system integrators and designers, the Tannoy CMS503DC-BM represents a sophisticated solution for achieving high-fidelity audio in visually sensitive applications. Its ability to deliver the sonic benefits of coaxial design from a completely concealed installation addresses the needs of premium commercial projects. This loudspeaker ensures that high-quality sound is delivered throughout a space without any visual intrusion, meeting the demands of clients who require both exceptional acoustic performance and impeccable interior design.
