I got M80 v3, noticed the sound wasn't balanced, surely enough one of the woofer is burned. While I figure how to go about getting replacement, I decided to swap them from VP180. Surprised to find both in the VP180 are blown too.

I am driving them from a Marantz SR6006. Could that be the culprit or just bad batch as I bought them all together. I am particularly surprised about the VP180 as it has barely seen 50 hours of usage in last 5 years or so that I have had these. Further its center channel, so would it really get driven hard like i do my M80s when listening to music. Furthermore, the cutoff on the Marants is set to 80 hz as I sent everything else to my sub, meaning to say woofers are being used in a very narrow range.

I am obviously getting these fixed, question is how do I ensure this doesn't happen again. Could this been a bad batch of woofers, is there such a thing?
