OWNER'S MANUAL
1OTW1-4 Subwoofer Driver
Congratulations on your purchase ofa ]L Audio subwoofer component. Your JL Audio subwoofer
is a precision loudspeaker which has been engineered to produce the highest quality sub-bass
performance in your vehicle. Authorized ]L Audio dealers have extensive technical information
for many different applications of your new speaker. They also have the knowledge, skills and tools
to build a high-quality enclosure that will maximize the performance of your speaker. We highly
recommend that you have your enclosure built by an authorized ]L Audio dealer.
Inside you will find specifications and two recommended enclosures for your speaker; one is a
sealed enclosure, the other is aported design. Both types of enclosures will give you excellent sound
quality and low-frequency extension. The sealed enclosure is a better choice if space is extremely
tight, but the ported enclosure will produce 3dB more output at the same power if you have the
extra space to work with.

JL
Audio offersan extensive
line
of
high-performancesubwooferdrivers
to
fit
a
wide
variety
of
enclosure
and
powerapplications.
When
designing systems
with
our
drivers,
it
is very
important
to
achieve a
good
powermatch
between
the
subwoofer
amplifier
and
the
subwooferdriver'scapabilities. The
power
levels listed in
the
abovechartrepresent continuous
(RMS)
amplifier
power
per
woofer
and assume
that
the
user will regularly makefull use
of
that
power
without
drastically overdriving t
he
amplifier(s).
Make
sure you factor system impedance
and
the
total
number
of
subwoofers i
nto
your
calculations.
Adhering
to
these power recommendations will result
in
systems
that
are
both
reliable and enjoyable.
