Martin Logan SL3 repair


Does anyone know where I can get Martin Logan SL3s serviced in the USA?
Martin Logan stated that they do not repair these speakers anymore.

The reason I ask is that the panel may just need cleaning. There is an instructional video on that somewhere. Might do the trick.  
Forgot to mention no smoking env. 
So is washing panels an ML sanctioned thing?  Has this been known to fix a channel imbalance?
If stator is the problem, Martin Logan will build you brand new stator with updated spec. But it will cost ya.
