12TW3 Subwoofer Driver
Congratulations on your purchase of a JL 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 JL 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 JL Audio dealer.
Inside you will find specifications and two recommended enclosures for your speaker; one is a
sealed enclosure, the other is a ported 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 12TW3-D4 / 12TW3-D8 12TW3 Dual Voice Coil Wiring
Please Note: The TW3 is a dual voice coil driver.
BOTH voice coils must be connected to the amplifier
(in series or parallel) for the speaker to operate
properly. To accomplish this, each TW3 features a pair
of main input connection push-terminals for each
voice coil. Verify that the connections are properly
configured based on these wiring diagrams to
achieve the desired load prior to sending signal to
the subwoofer.
All specifications are subject to change without notice.
* Xmax specifications are derived via one-way voice coil overhang method with no correction factors applied.
** Efficiency (1W/1m) is not an accurate indicator of a subwoofer’s output capability and should not be used as a comparison to
other subwoofers to determine which one is “louder” !
*** Re (DC resistance) is measured with the voice coils in series, for parallel-wired specification divide Re by 4. All other specifications
remain the same.

• The enclosure recommendations listed are external
dimensions which assume the use of 3/4" (19mm)
thick material. If you are using 5/8" (16mm) thick
material, subtract 1/4" (6.5mm) from each dimension.
Do not use any material with a thickness of less than
5/8" (16mm) as this may compromise the rigidity of
the enclosure.
• Enclosure volumes listed are net internal volumes!
Box volume displacement, port displacement and
brace displacement must be added to obtain the
final gross internal volume. All enclosure dimensions
listed have already taken this into account.
• When using two subwoofers in a common
enclosure simply double the required volume.
• We recommend the use of this speaker in a bi-amplified
system using high-quality satellite speakers and
amplifiers. We do not recommend the use of this
subwoofer with a passive crossover (coil), as this type of
device will adversely affect performance.

(End correction accounted for)
Prolonged exposure to sound pressure levels in excess of 100dB can cause permanent hearing loss. This high-performance
speaker can exceed this level. Please exercise restraint in its operation in order to preserve your ability to enjoy its fidelity.
When installing a subwoofer in your vehicle, it is extremely important to secure the enclosure firmly. We recommend
bolting the enclosure through the metal of the floorpan or the frame of the vehicle with large diameter washers
for reinforcement. If an enclosure is not firmly attached, it can become a projectile in a collision. This is particularly
important in a hatchback, station wagon, sports utility vehicle, or van.
