I have a pair of Axiom M40ti's that are about 7 months old that I will be willing to sell for 350 + shipping or trade for a SVS PB1-ISD. Whichever is fine. I'm willing to allow for local pickup in Austin or drive for one hour to the surrounding area. I also have a place in Houston so if you want to buy or trade there I'm willing to meet up there but only when time permits. These are still in great condition. Just want to replace them with a nice sub for hometheater.
