Those speakers are new, and under warranty. I would contact Martin Logan about that and get it repaired. I just take my hardware into the dealer here and they either fix it or send it back to Martin Logan for me.
I don't know if it's possible, but if you end up sending them back to Martin Logan, you might be able to exchange them toward a different model speaker. I had a brand new Marantz receiver that was broken out of the box and I decided to trade up to one level higher because I was paranoid about that model. It was no problem for me to do so. Not sure how long you've owned these new speakers.
