JL Audio 13TW5v2-4 Thin-Line 13.5″ Single 4 Ohm Subwoofer
The JL Audio 13TW5v2-4 redefines what’s possible in space-limited car audio builds. At only 67 mm (2.625 inches) of mounting depth, this engineering marvel delivers the deep, articulate, powerful sub-bass JL Audio is renowned for — without demanding the space of a conventional subwoofer. Whether you’re working with a sedan trunk, an SUV cargo area, or a custom install, the TW5v2 fits where others simply can’t.
Key Features
- Ultra-Shallow Mounting Depth: At just 2.625 inches deep, this 13.5″ subwoofer installs in spaces that would normally only accommodate smaller drivers.
- 13.5″ Driver in a 12″ Footprint: The purpose-engineered tab-ear cast-alloy frame allows the TW5v2 to fit within roughly the same mounting footprint as a conventional 12″ woofer.
- Massive 7″ Voice Coil: A patented concentric tube structure supports a 7-inch diameter voice coil, delivering exceptional power handling, stability, and control within a compact frame.
- DMA-Optimised Motor Design: Dynamic Motor Analysis ensures long, linear excursion with minimal distortion, producing tight, clean, articulate bass at every power level.
- FCAM Technology: The Floating Cone Attach Method bonds the surround and cone assembly to the former and spider structure for precise excursion control and superior dynamic performance.
- Concentric Tube Suspension: This patented suspension system supports the voice coil and full annular spider, allowing a larger motor structure to be positioned farther forward than conventional designs permit.
- Mineral-Filled Polypropylene Cone: The injection-moulded, mica-filled polypropylene cone paired with a resilient synthetic rubber surround maintains low distortion and full-bodied output even under heavy excursion.
- 13% More Linear Excursion: Improved over the previous W6v3 series, delivering noticeably deeper and more controlled bass reproduction.
- Minimal Enclosure Volume: Optimised for just 0.8 cubic feet, compatible with sealed or ported enclosures — smaller than most 10″ woofer boxes.
- Broad Power Compatibility: Pairs perfectly with amplifiers delivering 250 to 600 watts RMS across a wide variety of vehicle applications.
