I don't think it is out of protocol at all, It bugs the crap out of me that Avatar does not take returns (I understand why they don't and they have good reason not to). It is the reason I do not buy Avatar, I want to, I really do but I do not want to get stuck with a cab that does not work for me.
If any one in the North Texas area that would not mind me trying theirs out, I would love that, I will bet that I would love it and a 4ohm tb153 would be being delivered to my house the next week
