Practically brand new, used for about a month with a 100w amp. I am selling because I have a newer setup (3 x JL10W6's)

This sub has the potential to pound and hit pretty damn hard.

From JL's website:

The 15W3 was the first JL Audio subwoofer driver to combine our patented VRC Technology with our patented cross-drilled pole piece. These technologies lead to exceptional thermal stability which benefits reliability and sound quality. Combined with the 15W3's extremely long excursion capability, these benefits make this speaker a natural for high SPL applications as well as the most critical sound quality applications. The 15W3 is well-suited for sealed and ported enclosures and its dual voice coil design gives the user a high degree of application flexibility.
