The Tannoy CMS 1201 Grille Assembly is a dedicated accessory designed to provide a finished, protective, and acoustically transparent front for compatible CMS 1201 series ceiling loudspeakers and subwoofers. Its primary function is to conceal the speaker's internal components and driver while allowing sound waves to pass through with minimal interference, ensuring the speaker's performance is not compromised. The grille contributes significantly to the aesthetic integration of the speaker into a ceiling, typically featuring a paintable, white finish that can be customized to match the surrounding decor. For commercial and residential installations where visual discretion is important, this grille assembly provides a clean, low-profile appearance that blends seamlessly into the ceiling plane.

Constructed from durable, perforated metal or robust composite material, the grille is engineered to be both sturdy and acoustically favorable. The precise pattern and size of the perforations are designed to minimize diffraction and high-frequency attenuation, preserving the speaker's intended frequency response and dispersion characteristics. The assembly typically includes a mounting frame or bezel that secures the grille to the speaker chassis, often utilizing a magnetic attachment, friction fit, or screw-fastened system for secure and easy installation and removal. This allows for quick access to the speaker driver for service or adjustment without damaging the ceiling finish.

As an essential part of a complete installation, the grille assembly ensures a professional, code-compliant finish. It protects the speaker cone from accidental damage, dust, and debris, extending the loudspeaker's longevity. By offering a standardized, paintable finish and a design optimized for sound transmission, this accessory allows installers and homeowners to achieve both superior audio performance and a visually unobtrusive installation, upholding the professional quality associated with the Tannoy CMS series.
