The Tannoy TA-DVS 401-WH is a professional-grade, surface-mount coaxial loudspeaker engineered for high-fidelity background music and clear speech reproduction in commercial audio distribution systems. Its design features a four-inch coaxial driver, where the high-frequency tweeter is concentrically mounted within the larger woofer, ensuring precise point-source acoustics and uniform dispersion for consistent sound coverage throughout an installation zone. The speaker is housed in a compact, durable white enclosure designed for unobtrusive surface mounting on walls or ceilings, making it suitable for a wide array of applications including retail stores, restaurants, offices, hotels, and public buildings.

A key professional feature of this model is its integrated multi-tap line-matching transformer. This transformer allows the speaker to be safely and efficiently connected to a constant-voltage (typically 70V or 100V) amplifier system, which is the standard for driving multiple loudspeakers over long cable runs in commercial installations. The multi-tap design provides selectable power settings, enabling installers to balance the volume output of each speaker within the overall system by choosing an appropriate wattage tap. This ensures optimal sound pressure levels are achieved in different zones without overdriving or underutilizing any single unit.

Built with reliability and sonic clarity in mind, the speaker offers a well-balanced frequency response tailored for intelligibility and musicality in distributed audio environments. Its robust construction is designed to withstand the demands of continuous operation in public spaces. By combining the acoustic benefits of coaxial driver technology with the practical necessities of transformer-based commercial installation, the Tannoy TA-DVS 401-WH provides a versatile and high-performance solution for integrators seeking reliable, high-quality sound reinforcement in demanding fixed installations.
