The Tannoy CVS 401 is a compact 4-inch coaxial in-ceiling loudspeaker designed for flexible and discreet audio distribution in residential and small commercial installations. This speaker is engineered to provide clear, balanced sound for background music and voice reinforcement in spaces where larger speakers are impractical or where visual discretion is a priority, such as in bathrooms, hallways, kitchens, small offices, or retail boutiques. Its coaxial design integrates a 19mm soft-dome tweeter concentrically within the 4-inch bass/midrange driver, creating a unified point source that delivers coherent sound with consistent off-axis response. This configuration minimizes phase issues and provides a smooth frequency response, ensuring that music and speech are reproduced with clarity and presence even at lower volume levels.

Constructed for reliable performance, the CVS 401 features a rigid, injection-molded polypropylene enclosure that provides a stable acoustic environment. The paintable, magnetically attached grille allows for seamless color matching to ceiling finishes, making the speaker virtually invisible once installed. The driver utilizes a mineral-loaded polypropylene cone for accurate midrange reproduction and a ferrofluid-cooled tweeter for detailed high frequencies. Installation is simplified by a rotating cam system that securely locks the speaker into a standard ceiling cutout without requiring access from above, making it an ideal choice for both new construction and retrofit projects. The spring-clip terminals support quick-connect wiring, further streamlining the installation process.

For custom integrators and DIY installers seeking an affordable, high-quality solution for distributed audio, the Tannoy CVS 401 offers an excellent balance of performance, size, and value. Its compact form factor allows for installation in tight ceiling spaces, while its coaxial design ensures superior sound quality compared to many similarly sized speakers. This loudspeaker is a versatile component for building multi-room audio systems, providing clear and enjoyable sound that enhances the environment without drawing visual attention.
