INTRODUCTION

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 ’08 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 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 developed for attaching
nose cones on ICBM missiles –truly an
aerospace-grade adhesive. The spider
and surround are bonded to the frame
with a high strength toughened-
cyanoacrylate adhesive, which is also
used to bond the dust cap to the cone.

The magnet structure includes subtle
changes to its geometry that improve
power handling. While it appears the
same as the standard structure, and
replacement baskets from the ’08 BWX
series will fit on standard BW magnet
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 flat mid-bass response for an
accurate, clean sound quality.

REPLACEMENT OF SPEAKER BASKET ASSEMBLY

1. Prior to replacement procedure, clean work area of all metal objects and other debris.
2. With speaker lying face down, remove the three screws on back of magnet structure with 7/16"

nut driver.
3.. After screws are removed, lift the magnet structure off the basket frame.
4. Clean the voice coil “gap” before magnet structure is put on new replacement basket. (See

illustration.) Fold a piece of masking tape over on itself several times, sticky side out, and insert it
into the voice coil “gap.” Run it all the way around the “gap” several times to remove all particles of
metal and other trash before magnet structure is put on new replacement basket.
5. Holding magnet structure in slanted position, gently lower the structure down into the basket so

that it rests inside the magnet structure counter bore, being sure to align the screw holes, and
lower the structure down into place. Insert screws and tighten.
