I am looking to buy either a pb12-plus2 or a pbultra/2. i just sold my svs tube subs to get a box style sub. I may end up just buying from svs but thought i'd see if there were any good deals to be had from someone looking to upgrade/change from whatever they currently have. shipping is a concern and i am located in southern, nh. i am willing to drive a couple hundred miles to pick-up a sub. thanx, John s.
