JL Audio 12TW3-D4

Building on the core technologies developed for the TW5 thin-line subwoofers, the TW3 series embodies a powerful combination of shallow mounting depth and long linear excursion capability. The result is a speaker that delivers big, impressive sub-bass performance in a compact form that works for those snug-fit installations. Thanks to the TW3 thin-line architecture, the deep, powerful and articulate JL Audio bass is now accessible in more applications than ever. The 10-inch subwoofers require only 3.25 inches of mounting depth, while the 12-inch models take just 3.50 inches.

An aluminum-alloy dust cap aids with heat dissipation, extending the speaker’s power handling range. A JL Audio logo adds a finishing accent to the dust cap’s rich satin black finish. Known for its durability, the TW3 series’ injection-molded, mica-filled polypropylene cone design offers impressive frequency response and deep, powerful bass reproduction with minimal distortion. Proprietary motor, suspension and cone modeling systems are used to achieve long, linear excursion capabilities with low distortion and powerful sound output. The result is tight, clean, articulate bass performance at all power levels.
