Thankfully, this didn't happen in the theater room... but rather my gym. Unfortunately, I was in the room when it happened. Short-end of the story is the home gym has a 4.1 system in it. Nothing complex or expensive (save for the GoldenEar Super Sub X, which was retasked from another system I'd been planning to build), an inexpensive Pioneer VSX-521 powering four 10" Polk Audio in ceilings, with Apple TV and an Oppo BD player (that's never used). Last week, music cranking and all of a sudden this max volume digitalized high-pitch sound exploded from the speakers. It was ear crushing/deafening! I quickly hit pause on the music that was streaming... didn't stop the sound. Nor did attempting to attenuate volume. So, cut the power.

This event either destroyed the x-over in each speaker or outrig ht damaged the tweeters. Hard to say. But all high frequencies have ceased to work.

Needless to say, the Pioneer is on its way to the county recycling center. It's been replaced by a Marantz SR7012 that's been been sitting dormant. I attempted to just switch the AVR out (in hopes the sound issues were due to the reciever, itself, and not the speakers). No luck, though. So, I purchased four Monoprice Alpha Series inceilings (the same ones I reviewed earlier this year) and will be installing them today.

Anyone else ever had an AVR go nuts and take out speakers???

Certainly disappointed, but I think I'll end up with better sound performance and more functionality from an AVR perspective.

monoprice does a great job with eco friendly packaging... all of it is recyclable (even the plastic bags that cover each speaker). Very minimal Packaging that’s super easy to access.

Install was a snap... with Aud. Mult EQ XT32 onboard... plus these monoprice in ceilings (that perform crazy well for the $), the sound in the gym is levels above where it was!

What a bummer... although a good excuse to get new toys, right?

Hey... I had a $10k processor in my theater room causing havoc with my stats... scary for sure. Not just one, but two units.

Good point, I’d forgotten about that happening to you. Your stats are infinitely more valuable than the polk speakers I lost.

Weirdly, I’ve owned this receiver for about 10 years.... never had a single issue.
