Tang Band WT-1427B 10" Neo Subwoofer virtually new. I bought the 10" TB to build a subwoofer. However my box making skills aren't too good. I cut the whole slightly too large with a saber saw. It leaked air and the box was poorly consructed. I had it hooked up for 5 minutes before scrapping the whole project. It sounded like it would make for a really detailed sub though. I'm asking $55 including shipping in the US. PayPal would be a great way to pay!
