Contact Russ at HomeOK, so mine lasted two months. The panels on my Sequels are now officially dead after having come back alive very well (they're still listenable, but at low volumes). I am now back to square one. I still do not want to invest in expensive panels ($2600) on speakers that are 33 years old. I suppose ML has improved the rest of the speaker over the years, from what I have read, so now it's a toss between spending $5000 on a new pair of MLs or switching to Maggies. Your thoughts are welcome, thank you.
I had him repair mine. I would say they are about 80% the performance of brand new panels, and it cost me a very small fraction of the price.
