The Low Rider driver series
represents a milestone in high-
powered sub-woofer design. An
incredible 1,600 Watt program
rating and extra-long cone
excursion provide maximum
amounts of amazingly clean, deep
bass.
The Low Rider is a superior choice
for the bottom end of any high-
powered sound system, from DJ
rigs to the largest professional
touring shows.
DESIGN
The Low Rider utilizes a
variation on the existing Kevlar®-
impregnated cones used on all
Black Widow® speakers. The cone
is stronger and tougher and uses
an innovative asymmetrical -M
surround for superior excursion
and motion control.
High quality spring terminals
accepting large gauge wire are
attached to large diameter high-
current tinsel leads with silver
solder to withstand high currents,
high temperatures and long
excursion.
The massive new voice coil uses
polyimide-insulated copper ribbon
wire, edge-wound and bonded
onto an incredibly durable and
heat-resistant polyimide composite
former. The coil’s winding length of
1.150” is an amazing 80% longer
than Peavey’s standard Black
Widow coil. The long coil has a
large surface area to dissipate
heat, and its increased length
drives the cone to a far higher
excursion. The coil is over coated
with a tough thermoset epoxy
for added durability, abrasion
resistance and heat dissipation.
The coil wires are solderless
diffusion welded to high-
conductivity OFHC copper ribbon
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,
incredibly tough plastiseal-coated
Nomex® progressive-roll spider
using a thermoset epoxy originally
developed for attaching nose
cones onto ICBM missiles — truly
an aerospace grade adhesive. The
spider and surround are bonded to
the frame with a strong, toughened
cyanoacrylate adhesive, which is
also used to bond the dust cap to
the cone.
The magnet structure is all new
and was designed using extensive
Finite Element computer modeling.
The back plate/pole piece is cold
forged from a single massive billet
of ultra low carbon steel, included
Peavey’s patented Focused Field
Geometry and is undercut to allow
greater coil travel. The pole is
extended beyond the front plate to
improve coil cooling and make it
more magnetically linear and the
front plate is 10mm thick to match
the long voice coil and provide a
better path for heat and magnetic
energy. The result is 50% more
total magnetic gap energy than
can be found in the standard Black
Widow Super Structure magnet
assembly.
A patent pending vent plate greatly
improves voice coil cooling. This
heat conductive, ported and nned
aluminum ring delivers cool air
pumped by the spider directly to
the voice coil to keep operating
temperatures under control. The
improved cooling increases power
handling and reliability and reduce
power compression.
The cast aluminum frame is tough
and rigid and has the strength
needed to hold the cone and
huge magnet assembly in perfect
alignment. The deep dish design
and large spider clearance make
high excursion and high output
possible.
These dynamic new drivers
also utilize the user friendly
Black Widow replaceable basket
assemblies with Rubatex® gaskets.
The result of these specially
designed components are truly
amazing loudspeakers. The Low
Rider’s astonishing low frequency
output is due to its high power
handling capability and its 1.4” of
available cone movement. These
speakers can also be used with
small enclosures, adding a new
dimension to compact, high output
sound reinforcement systems.
APPLICATIONS
The Low Rider® is specically
designed for sub woofer use, with
extremely high output capabilities
and massive power handling.
While most sub woofer applications
are below 150 Hz, it is usable to
frequencies as high as 500 Hz.
The compact enclosure
designs are ideal for instrument
amplication and high portability
applications such as DJ and small
touring bands. They provide solid
bass performance in extraordinarily
small enclosures. Band pass
enclosures also t into this range
as standalone sub woofers.
The medium sized enclosures
are still smaller than usual and
have more bass extension and
much higher output capabilities
than conventional designs. They
are excellent choices for high
performance sound reinforcement.
These designs are the best
combination of size and bass
performance.
For permanent installations and
applications requiring extremely
deep bass performance, the large
vented enclosures are ideal.
The low frequency extension
and high sound pressure levels
these systems can produce
is astounding. As is typical in
large, vented systems with low
vent tuning, power handling is
reduced by at least 15% due to the
increased cone excursion.
Due to the Low Rider’s high
output capabilities, excessive level
may cause structural damage to
buildings or induce permanent
hearing loss, nausea, vertigo or
intestinal disturbances in listeners.
Please be cautious when setting
maximum sound pressure levels.
ENCLOSURES
To assist with the growing interest
in home built enclosure designs,
Peavey includes complete
parameter data on these drivers
and also provides the user with
several recommended enclosure
designs. This information and
much more can be found at www.
peavey.com.
The 18” Low Rider driver performs
best with vented enclosure
between 5 and 9 cubic feet (142 to
255 liters) and vent tunings from
30 to 45 Hz. The Low Rider 18
is optimized for vented systems
but will also work with appropriate
single reex bandpass enclosures.
Sealed, innite bafe, horn,
transmission line and dual reex
bandpass enclosures are not
recommended.
The Low Rider 15” driver works
best in vented enclosures between
2 and 5 cubic feet (56.6 to 141.6
liters) and vent tunings from 34
to 45 Hz. It can also be used in
certain single reex bandpass
designs. As with the Low Rider
18, sealed, innite bafe, horn,
transmission line and dual reex
bandpass enclosures are not
recommended.
Active ltering must be included
with ampliers greater than 750
watts. This lter should be a
high pass 24dB Butterworth at a
minimum of 25 Hz for the 18” and
32 Hz for the 15”. Filtering is also
recommended below 750 watts
in order to conserve amplier
power and reduce excessive cone
motion. Failure to use ltering with
high power operation may cause
driver damage that can void your
warranty.
Strength of the completed
enclosure has a great effect on the
bass performance of the nished
system. Internal bracing is required
to improve the structural strength
of the cabinet. Low Riders can
generate enormous forces inside
the enclosure, and panels that
aren’t tiff enough will vibrate or
if the cabinet panels are not stiff
enough add more bracing.
Vents shown in the examples
require standard Schedule 40 PVC
pipe for vent construction. The pipe
should be dadoed tightly into the
back of the bafe and glued rmly
in place with high quality epoxy or
high strength industrial grade hot
glue. Roughen up the outside of
the pipe to improve the glue bond.
Radius the insides of the vent end
to improve air ow and reduce vent
noise.
Vents for these enclosures
are much longer than typical
for a sound reinforcement sub
woofer. This reects the special
characteristics of the Low Riders
design that make it possible to
combine a large, high excursion
woofer with an unusually small
enclosure. For best performance,
the inside ends of the vents should
be a distance of at least one vent
diameter from any interior wall of
the enclosure. The vent should
be straight, without elbow ttings
or other methods to bend it for
greater length. Vent diameter
should not be decreased, as high
air velocity will result in noise and
reduced power handling.
Be sure to allow for the
displacement of the vent, bracing
and woofer in your enclosure
design before building it. Mistakes
in net volume will mis-tune the
enclosure and can drastically
reduce performance. This requires
a considerably amount of planning
before construction, but is well
worth the extra effort.
Line the inside of the enclosure
with polyester ber batting such
as quilt stufng. For bandpass
loosely ll the sealed side, leave
the vented side empty, and
place the low Rider’s magnet in
the vented side for cooling. 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 crossovers are available
through Peavey Accessories. Take
particular care when positioning
handles, as sub woofers tend to be
large and heavy.
Do not use ¼” phone plugs or
jacks in the construction of your
enclosures. Power capacity of
Low Rider sub woofers is well
above safe limits for phone
plugs and jacks. Neutrik®
Speakon® connector’s are highly
recommended, and internal
cabinet wiring should be at least 16
gauge stranded copper wire.
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 design,
construction or operation of
enclosures using this information.
Due to Peavey’s continuing efforts
to improve products, features
and specications are subject to
change without notice.
