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 com-
parable models, along with reduced
distortion and higher overall sound
quality.
The series includes 12” and 15” mod-
els 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 re-
sistant, 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 ex-
tremely 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 assem-
bly 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 fit 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, re-
placeable basket assemblies, Ruba-
tex gaskets and high reliability, spring
loaded terminals are all used.
