Martin Logans and Smokers

Yes, this can be a problem. The panels will attract everything that's in the air. Pollen/dust/smoke. You name it. But if you unplug them overnight (or longer) once every six months and vacuum them with the strongest shop vac you can find, they will jump back to life. This advice is per the manual and via email from Jim Powers at ML who is THE tech guy at ML.

Tar build up can affect the speakers ability to draw a deep breath and therefore reproduce the deepest bass signals!

I bet you did not appreciate this response.

I appreciate both of your responses. I was just afraid I'd
get the answers I got. I'm already aware of vacuuming the panels once in awhile although my Kirby vacuum without any attatchment at the end of the hose is so strong it litterally sucks the diaphragm right up against the panel and I'm afraid it may tear it so I've been using the brush
end attatchment at the end of the hose. With all the smokers in the world I guess I was hoping they had maybe a spray on and wipe off type of remedy to nicotine build up problems on the diaphragms.
