In the time I've been here, I don't recall anyone ever saying that they needed to replace a crossover. For you to need to replace two is really odd.
I wonder if something else is going on up-stream?
yeah,thats what makes me scratch my head.I had to replace the xovers in my m80's about 6 months after I bought them,no problem since.the xovers that Axiom sent me were different from the originals.I have all my HT equipment on it's own circuit and run an adcom power conditioner.I think it's very strange I've had another xover go out on me.
