SYSTEM DESCRIPTION
The WR (Weather Resistant) series is a series
of products aimed at the outdoor installation
market.
This series is EN 54 certified according to the
EN 54-24:2008 standard ( Fire detection and fire

This series is composed of 3 base models:

– WR-6415 a 15” two-way
Each of these models will be offered in two
exposure ratings:
– CX “covered exposure” for applications where
cabinets are covered or protected.
– DX “direct exposure” where cabinets are
unprotected and directly exposed to the
environment.
The CX versions are protected with a thick
exterior Iso-Flex paint coating.
The DX versions augment the protection rating
by employing a supplementary fiberglass exterior
finish.
Stainless steel fittings and mounting hardware
are offered for both versions.
The WR-8826 models are equipped with the
M-1 driver employing a 1” annular diaphragm and
an 80º x 80º horn geometry.

D.A.S. loudspeakers equipped with robust 4”
voice coils and the M-75 compression driver with
1.5” exit and a 3” voice coil. These models with
60º x 40º horn geometry.
All the speaker components are treated for
weather resistance and extended durability in
extreme environments.
The WR series enclosures are manufactured
using exterior grade plywood. Black, white or
military grey color options are available in both
exposure ratings (IP56 according to IEC 60529
standards).
