The Tannoy CMS 503DC BM is a high-performance 5-inch full-range ceiling loudspeaker engineered for discrete, high-fidelity audio in commercial installation projects, featuring Tannoy's signature Dual Concentric driver technology in a blind-mount configuration. This model is designed for installation entirely above the ceiling tile line, with only a low-profile, paintable steel grille visible from the room below, creating a seamless and unobtrusive aesthetic that blends with modern architectural finishes. The Dual Concentric driver integrates a 25mm soft-dome tweeter within the center of a 5-inch bass/midrange cone, achieving perfect acoustic alignment from a single point source. This results in coherent sound dispersion with precise imaging, exceptional clarity, and a uniform listening experience across a wide area, making it ideal for background music, speech reinforcement, and audio-for-video in upscale retail environments, corporate boardrooms, luxury hospitality venues, and high-end residential spaces.

Constructed for durability and consistent performance, the loudspeaker features a rigid die-cast aluminum chassis and a mineral-loaded polypropylene cone that provides controlled bass response and long-term reliability. The Tulip Waveguide surrounding the tweeter optimizes high-frequency dispersion and improves off-axis response, ensuring consistent tonal balance throughout the coverage area. The CMS 503DC BM includes a built-in multi-tap transformer with multiple power settings for straightforward integration into 70V or 100V distributed audio systems, allowing installers to balance output levels across different zones easily. Its high sensitivity and power handling enable it to deliver ample volume with low distortion, even when driven by moderate-power amplifiers.

For system designers and custom integrators who prioritize both acoustic excellence and visual discretion, the Tannoy CMS 503DC BM offers an optimal solution. The blind-mount installation eliminates the need for a visible speaker enclosure, preserving clean ceiling lines while providing the sonic benefits of a true coaxial point-source design. This loudspeaker is a key component in creating immersive, high-quality audio environments where the technology remains hidden but the listening experience is prominently refined and engaging.
