WHAT YOU'LL LOVE
RECESSED SUSPENSION
With the TW1 subwoofers’ low-profile suspension design, most of the forward excursion of the driver occurs within the frame’s dimensions — requiring only 0.87 inches of frontal clearance, even with the supplied grille installed. This allows for more efficient use of space and increased enclosure volume within a given overall depth.
ENGINEERED FOR BIG SOUND FROM A SMALL ENCLOSURE
In keeping with their “tight spaces” mission, the TW1 subwoofers deliver a powerful combination of shallow mounting depth and outstanding excursion capability to generate smooth and powerful bass from a remarkably compact enclosure.
POLYPROPYLENE CONE TECHNOLOGY
Known for their durability and moisture-resistance in harsh environments, the TW1 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 DESIGN
Proprietary 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 DESIGN
Benefiting from years of JL Audio woofer design experience, the robust TW1 series speakers feature purpose-engineered cast-alloy frames with flat edges for tight grouping when mounting two or more speakers side-by-side.
POWERFULLY ADAPTABLE
On a wide range of vehicle applications, with sealed or ported enclosures, the TW1 subwoofers deliver superb sound quality and power handling. Both the 10- and 12-inch versions support pairing with amplifiers in the 75- to 300-watt range.
AUDIO TECHNOLOGIES
CONCENTRIC TUBE SUSPENSION TECHNOLOGY
The TW1 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 SYSTEM
Carefully engineered lead-wire design and attachments ensure controlled, quiet lead-wire behavior under the most extreme excursion demands.

Additional
The enclosure recommendations listed above are external dimensions which assume the use of 0.75 in (19 mm) thick material. 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.
