Produce Heart-pounding Bass

A car subwoofer with a shallow-mount design and many impressive features, the JL Audio 12TW3-D4 is the perfect upgrade for your car's factory subs. This 12-inch subwoofer can put in some heart-pounding bass and would not need too much space to be installed inside your vehicle.

Mica-filled Polypropylene Cone

The JL Audio 12TW3-D4 has a mica-filled polypropylene cone and a rubber surround, which gives the subwoofer the needed rigidity and durability to withstand the effects of extended usage at high volume levels while being able to produce an accurate bass response with only minimal distortion.

 

Clean Bass With Reduced Distortion

It uses JL Audio's DMA-optimized motor design, which helps reduce distortion while producing a clean and punchy low-frequency performance. The JL Audio 12TW3-D4 also has the company's famous Concentric Tube Suspension, which significantly improves the subwoofer's excursion, allowing for more air pressure and resulting in louder and better bass performance.
