I have a made in USA Polk Audio db12 sub...I got it new couple months back. played it for a little bit and got some other subs to mess with so its back in its box. they sell the same sub on ebay for $59 plus shipping. I will take $35 shipped for my barely used one. I got pics if interested.
what is the requirement? or shall I ask why you cant use either? if you just dont like them thats cool..just need to make sure there isnt something we missed..like mount depth or something
