The revolutionary weather resistant
BWX WR series of woofers have been
designed to perform at peak levels in
outdoor environments.
The series includes 10”, 12”, 15” and
18” models with 8 ohm impedance.
DESIGN
The BWX series uses a cone that is
a variation on the existing Kevlar
®
impregnated cones used on all Black
Widows. This cone is stronger and
tougher, highly weather resistant, and
has a specially designed surround.
The dust cap is also made of the
same extremely strong material.
Voice coil assemblies on the weather
resistant drivers use the thermoset
insulated aluminum or copper rib-
bon wire, bonded onto an incredibly
durable, heat resistant polyimide
composite former. The coil wires are
solderless diffusion welded to high
conductivity OFHC copper foil leads,
which are embedded inside the for-
mer assembly and soldered to the
tinsel leads with high temperature
silver solder. The solder joint is then
coated with a special thermally con-
ductive silicone adhesive for encap-
sulation and heat dissipation.
The voice coil assembly is bonded to
the weather resistant cone and super
tough nylon composite spider using a
thermoset epoxy originally developed
for attaching nose cones to ICBM
missiles – truly an aerospace grade
adhesive. The spider and surround
are bonded to the frame with a high
strength toughened adhesive.
For best performance results use
BWX magnet structures. The BWX
WR series replacement baskets will
fit on standard BW magnet struc
-
tures, however the optimal power
handling capacity will be compro-
mised.
These weather resistant drivers adhere
to the familiar features of Black Widow
products: cast aluminum frames, re-
placeable basket assemblies, Rubatex
gaskets and high reliability, spring
loaded terminals are all used.
