• 13.5" TW5 Flat Subwoofer with 600W @ 4 Ohm
• The best selling and most powerful flat subwoofer from JL Audio!

Features:

• JL's patented Thin-Line woofer technology compresses the 13TW5v2's architecture with a "concentric tube" structure that supports the 7-inch diameter voice coil and suspension mounts.
• This allows the large motor structure to be placed much further forward in the loudspeaker than conventional designs, while providing excellent linear excursion and mechanical stability.
  
• To get even more performance out of this technology, the v2 improves on the original 13TW5 with 13% greater linear excursion.
• The cast alloy chassis has also been modified for greater strength and the redesigned motor now features annular venting.
• The v2 is also available in versions with a 2-ohm and a 4-ohm voice coil to suit a wide range of applications.
• In keeping with its "tight spaces" mission, the 13TW5v2 is optimized for enclosures far smaller than most 12/13-inch woofers require, and only slightly larger than the airspace requirements of a typical small 10-inch woofer.
• The mounting system is designed to fit in approximately the same footprint as a typical 12-inch woofer.
• The 13TW5v2 is best used with amplifier power in the 250W - 600W range and is optimized for operation in a 22.7 L (0.80 cu. ft.) sealed enclosure.
• Never before has such high quality sub-bass been possible in the most demanding installation applications.
