The 1508 and 1208 driver series
represent a new level of power
and performance for Black Widow
loudspeakers. Power handling is
increased by 40% over other comparable models, along with reduced
distortion and higher overall sound
quality.
The series includes 12” and 15” models in both 4 and 8 ohm impedances.
DESIGN
The BWX series uses a new cone
that is a variation on the existing
Kevlar® impregnated cones used on
all Black Widows. The new cone is
stronger and tougher, highly water resistant, and has a specially designed
surround – a deep roll accordion
design on the 15”, and an innovative
asymmetrical-M style on the 12” that
improves mid range clarity. The dust
cap is also made of the same extremely strong material.
Voice coil assemblies on the new
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 Kevlar cone and new super
tough nylon composite spider using
a thermoset epoxy originally develop
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.
The magnet structure includes subtle
changes to its geometry that improve
power handling. While it appears the
same as the standard structure, and
replacement basket from the BWX
series will t on standard BW mag-
net structures, the improved power
handling will be compromised if the
standard structure is used.
These new drivers also 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 1508 and 1208 drivers are
excellent choices for a wide range
of sound reinforcement, high level
playback, subwoofer, and monitor applications.
The 1508sps driver is an excellent
choice for general purpose sound reinforcement, and is available in both
4 and 8 ohm versions. Enclosure size
is reasonable and bass / mid-bass
performance is strong. Its versatility
includes sealed and bandpass enclosure designs.
The 1508cu produces amazing bass
performance in small enclosures,
along with at mid-bass response for
an accurate, clean sound quality.
The 1508he is best used as the bottom end of a full range enclosure. It
has very high efciency for superior
output in the mid-bass and midrange. However, for pure subwoofer
applications, the 1508sps or 1508cu
are better choices.
The 1208sps works well in sealed
or vented enclosure designs, and
its smooth, extended frequency
response makes it an excellent midrange performer. It is available in 4
and 8 ohm versions.
Because the 1208sps’s 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 1208sps 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 or 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 cross-
overs 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.
