The Tannoy CVS4 is a compact, high-performance 4-inch coaxial in-ceiling loudspeaker designed for discreet, high-quality audio distribution in commercial and residential installation applications. It utilizes Tannoy's proprietary Dual Concentric coaxial driver technology, where the high-frequency tweeter is mounted concentrically within the center of the low-frequency woofer. This design ensures perfect acoustic alignment of the sound sources, resulting in a coherent wavefront with exceptional stereo imaging and a well-defined "sweet spot" over a wide listening area. The speaker is engineered to deliver clear, articulate sound for background music, paging systems, and distributed audio in environments such as retail stores, restaurants, offices, hotel corridors, and residential homes.

Engineered for ease of installation, the CVS4 features a shallow, low-profile back can that fits into standard ceiling cavities, making it suitable for retrofit projects. It includes a paintable, magnetically attached grille that blends seamlessly into the ceiling décor. The speaker offers multiple power tap settings (typically via a rotary selector on the terminal block) to match the amplifier's output voltage in constant voltage (70V/100V) systems, as well as an 8-ohm direct connection option for standard low-impedance applications. This flexibility allows system designers to integrate the speaker efficiently into a wide variety of audio distribution topologies.

Built with Tannoy's legacy of acoustic excellence, the CVS4 provides a balance of sonic performance, installation convenience, and aesthetic discretion. Its coaxial design delivers a more accurate and immersive listening experience than conventional in-ceiling speakers of similar size, making it an ideal choice for installations where space is limited but audio quality is important. By offering professional-grade sound in a compact, versatile format, it serves as a reliable component for creating consistent, high-fidelity audio coverage in multi-room systems.
