I purchased mine in May of 09 they are the anniversary edition with the aluminum frames they have been flawless till last month when I noticed the mid-tweeter panel on one speaker was lower then the other. suspecting the panel needed replacement I contacted ML it turned out it was in the electronics and the repair cost was about $200.00 Still the best speaker I have ever owned.

Thanks Ken. So did you you have to send your speakers back to fix your Electronics?

I am a fairly new owner of ML's and so far,thrilled with what I am hearing.Hoping for many years of trouble free pleasure!

Just short of 3 years here. No issues at all.

I was able to seperate the panel form the base that contains the electronics just sent the base back. pretty painless.
