Although you did mention it’s not well ventilated in my experience Denon’s tend to clip/distort long before they overheat. I’d be careful doing that again.

I had a sparing match at with someone at AVS who blew the tweeters in both his M60s by overdriving his Denon and was blaming Axiom because they make weak speakers that can’t handle the power that they claim. Axiom even replaced his tweeter and he still had his undies in a bundle though I’m still not sure he understands how amp power works.
