Tannoy DVS 401-WH 4" Coaxial Surface-Mount Loudspeaker with Transformer (White) - TA-DVS 401-WH

Product Overview

The Tannoy DVS 401-WH is a compact 4-inch coaxial surface-mount loudspeaker with a built-in 25 W line transformer in white, sold as a pair. Part of the DVS 1.0 Series, it drops straight onto 70V or 100V distributed systems or runs at 8 ohms, and its wide 107-degree conical pattern suits low ceilings and tight wall positions. IP64-rated with a UL 94 V-0 ABS enclosure and certified to EN 54-24 and UL 1480, it is equally at home in background music duty and life-safety voice alarm systems.

Product Description

Supplied as a pair, the DVS 401-WH is the smallest model in Tannoy's DVS 1.0 Series — a newer, weather-rated and life-safety-certified line, distinct from the earlier DVS 4t. A 100 mm (4-inch) mineral-filled polypropylene low-frequency driver is paired coaxially with a 20 mm ferrofluid-cooled soft-dome tweeter crossing over at 3,250 Hz, so the high and low frequencies radiate from a single acoustic axis. The result is an even 107-degree conical coverage pattern that holds its character off-axis, which matters most in the short-throw applications this model is built for: restaurants, retail aisles, corridors and back-of-house areas where speakers sit close to the listener and coverage overlap is unavoidable. Power handling is 25 W continuous, 50 W programme and 100 W peak, reaching 96 dB average and 102 dB peak SPL. The built-in transformer offers 25 W / 12.5 W / 6.3 W / 3.2 W taps at 70V and 25 W / 12.5 W / 6.3 W at 100V, plus a low-impedance position for 8-ohm direct drive. The enclosure is UV-resistant, UL 94 V-0 rated ABS in a semi-matte white finish that disappears against light walls and ceilings, fronted by a colour-matched aluminium mesh grille with dust protection and rated to IP64 for covered outdoor use. Phoenix/Euroblock connectors with link-thru simplify daisy-chained runs, a nitrile rubber terminal cover protects the connections, and a colour-matched yoke bracket with finger-adjustable hardware is included. EN 54-24:2008 and UL 1480 / UL 1480A certification make it eligible for voice evacuation systems.

Frequently Asked Questions

Is the DVS 401-WH sold individually or as a pair?
This listing is sold as a pair, supplying two surface-mount loudspeakers.

How is the DVS 401 different from the older DVS 4t?
The DVS 401 is part of the newer DVS 1.0 Series. It is IP64-rated, 8 ohms nominal, and certified to EN 54-24 and UL 1480 — none of which applies to the earlier DVS 4t. Do not substitute one for the other on spec.

Can it be used in a fire alarm or voice evacuation system?
Yes. It carries EN 54-24:2008 and UL 1480 / UL 1480A certification. Confirm the installation meets your local authority's requirements.

Does it work on 70V/100V distributed systems?
Yes. A 25 W transformer provides taps at both 70V and 100V, and a low-impedance position allows direct 8-ohm drive.

Can it be installed outdoors?
It is rated IP64, which suits covered outdoor positions. It is not intended for fully exposed installation.
