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.
The voice coil assembly is bonded to the

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.
