Selling my 12W7. I built a custom box for it out of 3/4" mdf. 2cu ft slot ported tuned to 36hz. I purchased an even more beastly sub than this one and need to sell this. Had it in my car a week. Still basically brand new. Selling for $300 w/ the box if you're local or $275 w/o it plus shipping. Box specs: 30x13.5x16.5"
