Product Information
Unleash Incredible Bass with Compact Precision
The JL Audio 10TW3-D4 subwoofer paired with our custom-crafted Proline X Micro Series enclosure delivers audiophile-grade bass in a space-efficient package that's perfect for today's vehicles. This powerful combination merges JL Audio's revolutionary thin-line technology with Proline X's meticulous engineering to create a bass solution that refuses to compromise on sound quality despite its compact footprint.
Advanced Engineering Meets Precision Craftsmanship
The JL Audio 10TW3-D4 features patented "concentric tube" technology that places the voice coil directly beneath the dust cap while positioning the motor structure further forward, creating remarkable excursion capabilities in an incredibly shallow package. Our Proline X Micro Series enclosure perfectly complements this innovative design, precision-crafted with premium 3/4" MDF and heavy internal bracing for optimal bass response and zero unwanted resonance.
Space-Saving Design Without Sonic Compromise

With an enclosure depth of just 5.25 inches and the subwoofer requiring only 3.25 inches of mounting depth, this extremely compact system can be installed in locations conventional subwoofers cannot reach. Our Micro Series enclosures' versatile stack fab design is tuned specifically for the 10TW3-D4's acoustic requirements, providing the perfect .50 cubic foot sealed environment to maximize bass performance while minimizing space requirements.

Premium Sound, Premium Construction
Designed and handcrafted in the USA, this combination represents the pinnacle of automotive audio engineering. The JL Audio subwoofer produces deep, accurate bass with impressive musicality and impact, while the ProLine X enclosure enhances every note with its acoustically optimized construction. Experience bass that's not just heard but felt, without sacrificing valuable cargo space
