Back to my comment about new speakers, that was in regards to wanting higher spl, i.e. not blowing the center speaker before your others. A center should certainly keep up with the L/Rs without blowing. Hard to know what went wrong from your description. I wasn't suggesting you get better speakers except in capability, not particularly flat response, if that's what you're referring to with flat ears and all. Now, if you have a lot of extra boost applied via eq to a speaker, I suppose that could have something to do with blowing a speaker...
