Overview THINK THIN. EXPERIENCE AWESOME.
Building on the core technologies developed for the TW5 thin-line subwoofers, the TW3 series embodies a powerful combination of shallow mounting depth and long linear excursion capability. The result is a speaker that delivers big, impressive sub-bass performance in a compact form that works for those snug-fit installations.

WHAT YOU’LL LOVEENGINEERED FOR BIG SOUND FROM TIGHT SPACESThanks to the TW3 thin-line architecture, the deep, powerful and articulate JL Audio bass is now accessible in more applications than ever. The 10-inch subwoofers require only 3.25 inches of mounting depth, while the 12-inch models take just 3.50 inches.
DESIGN ACCENTSAn aluminum-alloy dust cap aids with heat dissipation, extending the speaker’s power handling range. A JL Audio logo adds a finishing accent to the dust cap’s rich satin black finish.
POLYPROPYLENE CONE TECHNOLOGYKnown for its durability, the TW3 series’ injection-molded, mica-filled polypropylene cone design offers impressive frequency response and deep, powerful bass reproduction with minimal distortion.
DYNAMIC MOTOR ANALYSIS (DMA) OPTIMIZED DESIGNProprietary motor, suspension and cone modeling systems are used to achieve long, linear excursion capabilities with low distortion and powerful sound output. The result is tight, clean, articulate bass performance at all power levels.
SPACE-SAVING FRAME DESIGNBenefiting from years of JL Audio woofer design experience, the robust TW3 series speakers feature purpose-engineered cast-alloy frames that have been modified for even greater strength. A space-saving tab-ear frame design helps to maximize cone area within the woofer’s mounting footprint.
POWERFULLY ADAPTABLEOn a wide range of vehicle applications, with sealed or ported enclosures, the TW3 subwoofers deliver superb sound quality and power handling. Both the 10- and 12-inch versions support pairing with amplifiers in the 200- to 400-watt range.
AUDIO TECHNOLOGIESCONCENTRIC TUBE SUSPENSION TECHNOLOGYThe TW3 series features a patented concentric tube structure built into the injection-molded speaker cone body. This structure supports the voice coil and a full annular spider while permitting the placement of a large motor structure farther forward in the speaker than with conventional designs.
ENGINEERED LEAD-WIRE SYSTEMCarefully engineered lead-wire design and attachments ensure controlled, quiet lead-wire behavior under the most extreme excursion demands.

If you are using 0.625 in (16 mm) thick material, subtract 0.25 in (6.5 mm) from each dimension. Do not use any material with a thickness of less than 0.625 in (16 mm) as this may compromise the rigidity of the enclosure.
All enclosure volumes listed above are net internal volumes! Driver displacement, port displacement and brace displacement must be added to obtain the final gross internal volume. All enclosure dimensions above have already taken this into account.
When using multiples in a common enclosure you will need to recalculate the enclosure and port dimensions. For assistance please contact your authorized JL Audio dealer or JL Audio Technical Support.
We recommend the use of this in a bi-amplified system using high-quality satellites and a high-quality amplifier. We do not recommend the use of this with a passive crossover (coil), as this type of device will adversely affect performance.
