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 ribbon 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 former assembly and soldered to the
tinsel leads with high temperature
silver solder. The solder joint is then
coated with a special thermally conductive silicone adhesive for encapsulation 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
t on standard BW magnet structures, however the optimal power
handling capacity will be compromised.
These weather resistant drivers adhere
to the familiar features of Black Widow
products: cast aluminum frames, replaceable basket assemblies, Rubatex
gaskets and high reliability, spring
loaded terminals are all used.
APPLICATIONS
The weather resistant drivers are
excellent choices for a wide range
of sound reinforcement, high level
playback, subwoofer, and monitor applications.
The 1508 HE BWX WR driver is
best used as the bottom end of a full
range enclosure. It has very high ef-
ciency for superior output in the mid-
bass and mid-range.
The 1208 SPS BWX WR works
well in sealed or vented enclosure
designs, and its smooth, extended
frequency response makes it an excellent mid-range performer.
Because the 1208 SPS BWX WR low
frequency output is limited, it should
be used along with a subwoofer
when response below 60 Hz is needed. The best application for the 1208
SPS BWX WR is in compact enclosures and very high quality mid-bass/
mid-range reproduction at high sound
pressure levels.
The 15” drivers can work with crossover points as high as 2.0 kHz but
work best below 1.5 kHz. The 12” drivers are usable to 3.5 kHz but perform
best below 2.5 kHz.
ENCLOSURES
To assist with the growing interest
in home built enclosure designs,
Peavey provides complete parameter data on these drivers, as well as
several recommended enclosures
for each model. This information and
much more can be found at www.
peavey.com.
The strength of the completed enclosure has a great effect on the bass
performance of the nished system.
Box panels that aren’t stiff enough
will vibrate, canceling bass produced
by the woofer and creating undesired sounds of their own. If your box
vibrates or you don’t think the box
panels are stiff enough, add more
bracing.
Vents used in the examples require
standard Schedule 40 PVC pipe for
vent construction. The pipe should
be dadoed tightly into the back of the
bafe and glued rmly in place with
high quality epoxy or high strength,
industrial grade hot glue. Rough up
the outside of the pipe to improve the
glue bond.
Be sure to account for the displacement of the vent, bracing, horn (if
used) and woofer in your enclosure
before building it or it will be smaller
than its intended volume. This can
reduce bass output and mis-tune the
enclosure.
Line the inside of the enclosure with
polyester ber batting such as quilt
stufng. The batting material should
conform to California bedding re
codes. Attach the batting with spray
adhesive or staples and keep material away from the end of the vent tube
where it can be pulled in by air ow.
Handles, protective corners, cabinet
covering, grille materials and crossovers are available through Peavey
Accessories.
When building a bandpass enclosure, design a panel or door to be
removable for access to the woofer.
Use foam weather-strips to seal the
panel along with enough screws and
bracing to prevent leaks and buzzes.
Fill the sealed volume loosely with
polyester ber, but leave the vented
volume empty. Place the magnet of
the woofer in the vented side for improved cooling.
Peavey does not supply hardware
required for the manufacturing of ying systems, and recommends that
builders should not suspend or y
any enclosure not certied for such
applications.
These instructions are a general
guideline for design. Proper construction techniques, good planning and
common sense will result in a reliable, high quality, high performance
system.
Peavey in no way accepts liability for
any damage, accidents or injury that
may result from construction or use
of enclosure using this information.
Due to Peavey’s continuing efforts
to improve its products, features and
specications are subject to change
without notice.
PARAMETERS
Thiele-Small parameters for Black
