The Tannoy DVS 8T is a versatile and durable coaxial loudspeaker designed for commercial background music and public address systems requiring the flexibility of constant voltage operation. This surface-mount speaker features an 8-inch paper cone woofer integrated with a 1-inch titanium dome tweeter in a coaxial configuration, providing coherent, wide-dispersion sound from a single point source. Its primary distinction is the inclusion of a built-in multi-tap transformer, allowing it to be connected to 70V or 100V amplifier systems, which are standard for large-scale distributed audio installations where multiple speakers are wired in parallel over long cable runs. The enclosure is constructed from UV-stabilized polypropylene, making it resistant to environmental factors and suitable for both indoor and covered outdoor use in locations like retail stores, restaurants, warehouses, and hallways.

The coaxial driver design ensures consistent sound quality across a broad listening area, which is critical for maintaining clear speech intelligibility and pleasant music reproduction in commercial spaces. The integrated transformer features multiple power tap settings, enabling the installer to balance the volume levels across different zones by adjusting the amount of power each speaker draws from the central amplifier. This makes system design and zoning efficient and cost-effective. The speaker is highly efficient, capable of producing high sound pressure levels from relatively low amplifier power, contributing to an economical overall system design that does not sacrifice performance or coverage.

Installation is designed for simplicity and reliability. The rotatable enclosure allows for precise aiming of the sound field after the backplate is securely mounted to a wall or ceiling. All electrical connections and tap settings are accessed via a robust screw terminal block on the rear of the unit, which accommodates a wide range of wire gauges. With its combination of acoustic performance, transformer flexibility, and rugged construction, the DVS 8T serves as a dependable and practical audio solution for a vast array of commercial and institutional installation projects.
