Hey... i have two of the "older" 03 model of the 12Ks D4 (not flat).... One of the subs has a hole in the surround which HAS been sealed and there is no audibal difference..still a baddass sub..I am just looking to build up a system using only one 12 or one 15. So i would like to trade these great subs for something like a new 12 or 15A.. or anything around that level... i could also add a little cash... I could also sell these subs if the price is right. Thanks
