Martin Logan CLS panel distortion


Dear Audiophiles,
My original Martin Logan CLS speakers developed harsh distortion at higher spectrum of frequencies (mostly audible at high pitched soprano voices). Distortion disappears at low volumes of sound. Are my panels getting too old (they could be 10 years old, I am a third owner)? Is there a way to clean/tighten them (the panels, not owners ;-)? Your comments and suggestions will be appreciated. Thank you.

BTW... all CLS 1's,later serial # CLS II's and all CLS IIa's "power down" if no signal is received after 20 minutes. So the "air filter" theory goes out the window.
Yeah, seven years can realy try a man's patience. BTW, I've had near-new panels for five years. I guess the problems will be forthcoming. Maybe I should set up a wok near the speakers to expedite this. LOL. I seriously doubt that you have ever owned these speakers.
JohnK,

Let me get this straight...on another thread you claim that 5 of 8 ML speakers you've owned have "failed". I have not known 5 *owners* who have had these kinds of problems, (within a reasonable time frame -- let's say several years), let alone 5 times with *one* owner. The math just doesn't seem to work.

I am also curious as to why you suffered with 8 pairs of speakers to get 3 pairs that didn't fail. Am I missing something essential to your speaker preferences and decision making process?

BTW my listening room happens to be around the corner from my kitchen (crappy afterthought)*and* I fire up a wok 3 to 4 times a week (Thai food -- even though I am "falang"). Add L.A. air polution and I still do not have problems. Same goes for the Quad ESL 57's when they are in service.

Again, I'm not buying it. Not because I am "uptight" -- and I am just as a matter of course -- but because the facts do not jibe based on real world experiences. Mine and most others. ML's are far from perfect, but your other posts on this site where you state that there are "lots of problems with ML's" simply are not consistent with reality. These things are damn near indestructable notwithstanding normal wear and tear.

If I am mistaken and you have actually had 5 of 8 pairs of ML's fail, you should run for your life. For you are cursed. ;-)
