Unless you had the receiver at +15 or higher on your dial for extended periods of time, clipping the speakers, I find it so hard to believe you blew all those drivers. I just have never heard of this in the time I've been a member here.
Back when I was trying to isolate my POS Emotiva amp shutting down problems, there was a time where I drove just my rear Qs8's as front channels at +15dB on the volume dial for about 5 minutes. Now the dispersion was different than a direct radiating speaker, but they didn't break a sweat and I wasn't even touching the 400+ watt rating.
I just don't see how you could blow all these drivers unless someting is hooked up wrong, or your receiver is set wrong.
