JL Audio JL10TW1-2: 300 W 2 Ω Thin-Line Slim Subwoofer

Features:

• Built on JL Audio's patented Thin-Line Subwoofer technology, the JL10TW1-2 delivers a powerful combination of shallow mounting depth and excursion capability, while operating in insanely small enclosures (0.4 cubic FT / 10 L).  This, combined alongside a special cast alloy frame design, makes the JL10TW1-2 capable of operating in extremely tight spaces.  These include under and 2 seats installations in trucks, 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 JL10TW1-2 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 through conventional designs.
• The JL10TW1-2 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 JL10TW1-2 requires only 0.9" (22 mm) of frontal clearance, even through its grille installed.  This allows for more efficient use of space and increased enclosure volume within a given overall depth.
• Even though the JL10TW1-2 is optimized for an enclosure much smaller than any other JL Audio 10" Subwoofer, 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 (4.4" / 111 mm)
• No pole vent: permits mounting close to rear wall of enclosure
• Extremely small sealed enclosure volume requirements
• Long linear excursion capability (0.4" / 10 mm, 1 way)
• DMA optimized motor design
• Patented "concentric tube and floating cone attach method" architecture and technology
  
• Cast alloy frame through flat edges for tight driver grouping
• Injection molded, mica filled polypropylene cone
