Overview: TW3

JL Audio 12TW3 SubwooferTW3 (Thin-Line)
World-class performance and refined sound quality for challenging applications.

Sharing core technologies with its TW5 big brother, TW3 subwoofers deliver a powerful combination of shallow mounting depth and excursion capability. In fact, they are capable of greater excursion than the W3v3's. Utilizing our Tab-Ear mounting design that maximizes their cone area within their mounting footprints makes the TW3's ideal for challenging installations requiring excellent output and fidelity. TW3's are optimized to operate in very compact sealed enclosures to deliver deep, powerful and accurate bass. Available in 10 and 12-inch sizes with dual 4-ohm and dual 8-ohm voice coils for wiring versatility, all TW3's are built in our Miramar, Florida factory. Return to TW3 subwoofers.

Built in U.S.A. with Global Components

JL Audio's proprietary Dynamic Motor Analysis system is a powerful suite of FEA-based modeling systems, first developed by JL Audio in 1997 and refined over the years to scientifically address the issue of speaker motor linearity. This leads to vastly reduced distortion and faithfully reproduced transients... or put simply: tight, clean, articulate bass.

This frame design feature facilitates mounting the subwoofer driver in tight spaces. By employing a tab-ear mounting system, the driver's overall outside dimensions are reduced, permitting it to be mounted in a space that is very similar to that required by the next smaller round woofer frame.

Carefully engineered lead-wire design and attachments ensure controlled, quiet lead-wire behavior under the most extreme excursion demands. (U.S. Patent #7,356,157)

Our patented Concentric Tube Suspension™ technology delivers unprecedented excursion in a low-profile woofer. (U.S. Patent #5,734,132 & #6,095,280)

JL Audio's Miramar, Florida loudspeaker production facility is one of the most advanced in the world.
