Peavey 1508-8 CUCP Pro Rider 15" Low Frequency Speaker
Specifications: Size: 15" Power Rating: 600W AES Frequency Response: 35-2kHz Sensitivity: 97.9db Impedance: 8 ohms Voice Coil: 4" Voice Coil Material: Aluminum ribbon wire Polyimide-impregnated fiberglass former Nomex® stiffener Solderless diffusion welded OFHC copper leads Resonant Frequency: 34.8 Hz Weight: 18 lbs. Peavey Part No: 00560250
The Pro Rider® driver series
represents a new level of power and performance for Black Widow®
loudspeakers. These outstanding
drivers have a power handling rating
of 1,200 Watts program, along with
high ef ciency, reduced distortion
and excellent overall sound quality. The series includes two 15” models
in 8 Ohm impedance, suitable for both subwoofer and woofer
applications.
DESIGN
The Pro Rider 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 deep roll accordion
surround. 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,
edge wound and bonded onto an
incredibly durable, heat resistant polyamide composite ormer. The coil
wires are solderless diffusion welded
to high conductivity OFHC copper
foil leads which are embedded
inside the former assembly and
attached 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
adhesive.
The magnet structure includes subtle
changes to its geometry that improve
power handling. While it appears the
same as the standard structure, and
the replacement baskets from the
Pro Rider series will t on standard
BW magnet structures, the improved power handling will be compromised
if the standard structure is used.
The vent plate assembly used on
Low Rider® drivers to increase power
handling is included in the Pro Rider
series. This results in a signi cant
improvement in power handling capabilities and long-term power
compression. These new drivers also adhere to
the familiar features of Black Widow
products: Cast aluminum frames,
replaceable basket assemblies,
Rubatex® gaskets and highly
reliable, spring loaded terminals are
all used.
APPLICATION
The Pro Rider drivers are superior
choices for a wide range of sound
reinforcement, high level playback,
subwoofer and monitor applications.
The 1508-8 ALCP Pro Rider driver is an excellent choice for general
purpose sound reinforcement. The
enclosure size is reasonable and its
performance form sub bass to upper
mid-range is strong. Its versatility
included vented and bandpass
enclosure designs.
The 1508-8 cucp Pro Rider is
specially optimized for amazing
bass performance in very small
vented enclosures, along with at
mid-bass and mid-range response
for an accurate, clean sound quality.
It is an excellent choice for compact
enclosures, multi- driver subwoofers
and monitors where enclosure size
is limited. Pro Riders can work with crossover
points as high as 2.0 kHz, but work
best below 1.5 kHz. They deliver
excellent performance in both woofer
and subwoofer applications.
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 finished
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
baffle and glued firmly 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 fiber batting such as
quilt stuffing. The batting material
should conform to California bedding fire 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 flow. 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-strip to
seal the panel along with enough screws and bracing to prevent leaks
and buzzes.
