JL Audio 12TW3-D4 Thin-Line 12″ Dual 4 Ohm Car Subwoofer
The JL Audio 12TW3-D4 proves you don’t need a massive enclosure to feel serious bass. Built on the same core technologies as JL Audio’s acclaimed TW5 series, this 12-inch thin-line subwoofer combines an ultra-shallow mounting depth with long linear excursion capability — delivering deep, powerful, and articulate sub-bass performance even in the most space-constrained installations.
Key Features
- Shallow Mounting Depth: Only 3.50 inches deep, making it ideal for vehicles with limited installation space such as trucks, sports cars, and custom builds.
- Minimal Enclosure Requirements: Requires just 0.8 cubic feet, allowing for a compact sealed enclosure without sacrificing sound quality.
- DMA-Optimised Motor Design: JL Audio’s Dynamic Motor Analysis ensures long, linear excursion with low distortion for tight, clean, and powerful bass at every volume level.
- Polypropylene Cone Technology: Injection-moulded, mica-filled polypropylene cone delivers impressive frequency response and deep bass reproduction with minimal distortion.
- Concentric Tube Suspension: Patented concentric tube structure supports the voice coil and full annular spider, enabling a large motor structure positioned farther forward than conventional designs allow.
- Cast-Alloy Frame: Purpose-engineered for strength and rigidity, the space-saving tab-ear frame design maximises cone area within the woofer’s mounting footprint.
- Aluminium-Alloy Dust Cap: Aids heat dissipation to extend power handling range, finished in a rich satin black with JL Audio logo branding.
- Engineered Lead-Wire System: Precisely designed lead-wire attachments ensure controlled, quiet behaviour even under extreme excursion demands.
- Push-Button Terminals: Tool-free speaker connections for a clean and secure installation.
- 1-Year Warranty: Backed by JL Audio’s manufacturer warranty for peace of mind.
