I had two 15s about 6 years ago. And I sold the pair for $300. Wish I never did that. Nobody in my area was interested in them and most people didn't even know what they were. Some dude drove from the other side of the island to buy them from me. He was so stoked. He messaged me later that day that he dropped one of them while taking measurements and cracked the motor structure and magnet SMH. Not sure that the hell I was thinking back then LOL. But I used that $300 to pick up a brand new in box infinity kappa perfect 12 old school version. I still don't think it was worth doing though
