The Tannoy CVS401 is a professional 4-inch coaxial in-ceiling loudspeaker designed for high-quality distributed audio in commercial and residential installation applications. This compact model features a coaxial driver design where the high-frequency transducer is mounted concentrically within the low-frequency cone, ensuring sound from both drivers originates from the same acoustic point. This results in superior phase coherence, precise imaging, and uniform sound dispersion throughout the coverage area. The speaker is engineered for flush mounting into standard ceiling grids or plasterboard, featuring a low-profile, paintable grille that blends discreetly into the architectural environment, making it ideal for background music and paging in offices, retail spaces, hotel rooms, and corridors.

The loudspeaker is built with a rigid, fire-retardant enclosure that ensures stable acoustic performance and meets safety standards for commercial installations. It is designed for use in constant-voltage (70V/100V) systems, incorporating a multi-tap transformer that allows installers to select the appropriate power tap to match the speaker's output level to the specific zone requirements. This simplifies the design of large-scale audio systems where multiple speakers are driven over long cable runs from a single amplifier. The CVS401 delivers a balanced frequency response with clear midrange articulation and extended highs, providing both intelligible speech reproduction and pleasing music playback from its compact form factor.

For system integrators and designers, the Tannoy CVS401 offers a combination of proven coaxial technology, practical installation features, and reliable performance in a small size. Its transformer-based operation facilitates flexible system design, while the coaxial driver ensures consistent, high-quality audio coverage. The speaker's robust construction and straightforward installation make it a dependable choice for a wide range of commercial and custom residential projects where space is limited but audio quality, ease of integration, and visual discretion are important considerations.
