TW1 10-inch Subwoofer Driver (300 W, 4 Ω)

Built on JL Audio's patented thin-line subwoofer technology, the 10TW1 delivers a powerful combination of shallow mounting depth and excursion capability, while operating in insanely small enclosures (0.35 cu.ft. / 10 liters). This, combined with a special cast alloy frame design, makes the 10TW1 capable of operating in extremely tight spaces. These include under-seat installations in trucks, 2-seat sports cars and many other creative applications requiring a compact, low profile subwoofer design.

JL Audio's patented thin-line woofer technology compresses the architecture of the 10TW1 using a "concentric tube" structure built into the injection-molded cone body. This structure supports the voice coil and a full annular spider, while permitting the placement of a large motor structure further forward in the speaker than with conventional designs.

The 10TW1 also features a clever frame design that minimizes the frontal clearance required for the excursion of the driver. This is accomplished by recessing the suspension attachment surface, so that most of the forward excursion occurs within the frame's dimensions. Thanks to this feature, the 10TW1 requires only 0.87 inches (22 mm) of frontal clearance, even with its grille installed. This allows for more efficient use of space and increased enclosure volume within a given overall depth.

Even though the 10TW1 is optimized for an enclosure much smaller than any other JL Audio ten-inch subwoofer driver, it never sounds like a big woofer struggling in a tiny box...instead, it delivers all the rich, deep, controlled bass you have come to expect from a JL Audio subwoofer system.


  • Very shallow mounting depth (4.36 in / 111 mm)
  • No pole vent: permits mounting close to rear wall of enclosure
  • Extremely small sealed enclosure volume requirements
  • Long linear excursion capability (0.40 in / 10 mm, one-way)
  • DMA-optimized motor design
  • Patented "concentric tube" architecture
  • Patented "floating cone attach method" technology
  • Cast alloy frame with flat edges for tight driver grouping
  • Injection molded, mica-filled polypropylene cone
  • Rubber surround
  • Steel mesh grille included with each driver
  • Precision-built in USA at JL Audio's Miramar, Florida factory with global components
Technology
Dynamic Motor Analysis - DMA Optimized Motor

JL Audio's proprietary Dynamic Motor Analysis system is a powerful suite of FEA-based modeling systems, first developed by JL Audio in 1997 and refined over the years to scientifically address the issue of speaker motor linearity. This leads to vastly reduced distortion and faithfully reproduced transients... or put simply: tight, clean, articulate bass.

Engineered Lead-Wire System (U.S. Patent #7,356,157)

Carefully engineered lead-wire design and attachments ensure controlled, quiet lead-wire behavior under the most extreme excursion demands.

Tab-Ear Frame Design

This frame design feature facilitates mounting the subwoofer driver in tight spaces.

Concentric Tube Suspension

Our Concentric Tube Suspension™ technology delivers unprecedented excursion in a low-profile woofer.

Built in U.S.A. with Global Components

JL Audio's Miramar, Florida loudspeaker production facility is one of the most advanced in the world.

Extended warranties are usually very inexpensive and can save you thousands in the future. It's simple and inexpensive to purchase extended warranties and one of the smartest ways to protect your investment.

Electronics can be large, heavy and expensive. You probably don't have the special tools or expertise needed to fix them in a crisis. If you can spare a few thousand dollars without batting an eyelash for new electronics should they break tomorrow, don't buy a warranty. But if you're like most of us, protect yourself by purchasing inexpensive extended warranties when you buy a new product and save yourself big money in the long run.
