A True Bass Ultra 8, DVC2, asking $50:
All of the above are used, except the Sundown SA-8 V1. It was a recone from WooferCooker on a brand new basket, and I never got around to trying it out.
All prices are plus shipping, but are OBO. Just keep in mind, it cost me $25 to ship a 5 pound radio today. I don't even want to know what it will cost to ship a 15 plus pound subwoofer!
