The DVS 401-WH is a coaxial surface-mount loudspeaker engineered to provide superb audio performance in both background and foreground music sound systems. Ideally suited for a wide variety of applications, from restaurants and hotels to houses of worship and businesses of all types, the DVS 401-WH offers the power handling, wide frequency response and low distortion typically found in more expensive products. EN 54-24 certification for fire detection and fire alarm systems makes the DVS 401-WH the perfect choice where safety is a top priority. The loudspeaker is also UL 1480 certified for fire-protected signaling.

Exceptional Sound and Reliability
The design comprises a 100 mm (4.00") polypropylene full-range driver and 0.79" ferrofluid cooled soft dome high frequency driver mounted in a UV and weather resistant UL 94-V0 ABS enclosure. Dust protection is provided in the form of an attractive aluminum mesh grille. The paper cone material and butyl rubber surround enhance durability and long-term reliability. DVS 401-WH is specifically designed for applications requiring the combination of excellent music and speech sound quality and exceptional reliability.

Weather-Resistant Enclosure
The elegantly styled semi-matt white molded enclosure blends beautifully into any décor. Additionally, the DVS 401-WH design and performance has achieving an IP64 rating, making it an exceptional choice for both indoor and outdoor environments such as indoor swimming pools, health suites, or work areas with unusually high levels of dust or moisture, and outdoor applications where weather conditions are moderate.

Attractive and Easy to Install
The highly durable and scuff-resistant ABS enclosure features a white painted finish and comes with an aesthetically pleasing aluminum grille. Installation is quick and easy, thanks to the included color matched steel mounting bracket and finger-adjustable hardware on the enclosure top and bottom. Phoenix* connectors for input and link output are provided for convenience.

Architecture and Engineering Specifications
The speaker shall be of the full range, two-way passive type consisting of one 4" (100 mm) LF driver and one 0.75” (20 mm) HF driver. Performance specifications of a typical production unit shall meet or exceed the following: frequency response, measured with swept sine wave input, shall be flat within ±3 dB from 80 Hz to 20 kHz and within -10 dB from 70 Hz to 20 kHz. Nominal dispersion, at -6 dB points, shall be 107° conical, averaged 1kHz – 10 kHz. Nominal impedance shall be passive: 8 Ohms.

Power handling shall be passive: 25 Watts continuous, 100 Watts peak. Sensitivity, measured on axis, mean averaged over the stated bandwidth, shall be 82 dB, 1 Watt @ 1 meter.  Maximum SPL of 96 dB average measured at 1 m under free field conditions, using unweighted pink noise.

Dimensions: 287 mm high x 181 mm wide x 143 mm deep (11.30" x 7.13" x 5.63"). Net weight: 4.5 kg (9.9 lbs). The loudspeaker system shall be the Tannoy DVS 401-WH. No other loudspeaker shall be acceptable unless submitted data from an independent test laboratory verifies that the above combined performance/size specifications are equaled or exceeded.
