The Tannoy DVS 4 is a compact and versatile coaxial surface-mount loudspeaker designed for clear and reliable audio distribution in a wide range of commercial sound installations. This model features a 4-inch mineral-filled polypropylene woofer that is concentrically integrated with a 1-inch polyamide dome tweeter. This coaxial driver design ensures that both high and low-frequency sound originates from a single acoustic point, which promotes coherent wavefront generation, improved stereo imaging, and uniform sound dispersion throughout the listening space. Housed in a sealed, non-vented enclosure made from durable, high-impact ABS plastic, the loudspeaker is built to withstand the environmental conditions of typical indoor applications such as retail stores, restaurants, offices, and educational facilities, while its design helps prevent moisture ingress.

A key operational feature of the DVS 4 is its integrated multi-tap line-matching transformer, which provides extensive system compatibility. The transformer offers several selectable power settings, allowing for seamless integration into both 70V and 100V constant voltage public address systems, which are standard in commercial audio for powering multiple speakers over long cable runs. Additionally, it includes a direct 8-ohm bypass, enabling connection to standard low-impedance amplifiers for applications prioritizing audio fidelity. Installation is straightforward, facilitated by a removable front baffle and a pre-formed gasket that ensures an airtight seal against the mounting surface for optimal acoustic performance and a clean, professional finish.

Engineered for articulate vocal reinforcement and clear background music, the Tannoy DVS 4 balances good sensitivity with solid power handling in a discreet form factor. Its low-profile, perforated steel grille is finished in a neutral white, allowing it to blend inconspicuously with most interior decors. As a practical, cost-effective solution, this loudspeaker delivers the benefits of proven coaxial technology—consistent coverage and coherent sound—in a robust, easy-to-deploy package, making it a dependable choice for integrators addressing general-purpose audio needs in commercial environments.
