sun can cause deterioration of grill cloth, speaker cones, etc. Small exposures to UV will not cause a problem. In general, the filtering of UV rays through glass will greatly reduce the negative effects on the electrostatic membrane itself.
Will .excessive .smoke .or .dust .cause .any .problems .with . my .electrostatic .speakers? .
Exposure to excessive contaminants such as smoke or dust may potentially affect the performance of the electrostatic membrane, and may cause discoloration of the diaphragm membrane. When not in use for extended periods, you should unplug the speakers and cover them with the plastic bags in which the speakers were originally packed. It is a good idea to vacuum the electrostatic portion of each speaker three or four times a year. See the vacuuming FAQ.

Your speakers are dusty. See the vacuuming FAQ. The electrostatic charge on the element has attracted airborne dust or pollen. Since 1993, all of our speakers have been built with a charging circuit board that only charges the electrostatic element when music plays. At other times they are not charged and cannot collect dust.
Could .my .children, .pets, .or .myself .be .shocked .by .the .
No. High voltage with low current is not dangerous. As a matter of fact, the voltage in our speakers is 10 times less than the static electricity that builds up on the surface of your television screen.
How .do .MartinLogan .speakers .hold .up .over .a .long . term .in .the .humidity .of .tropical .climates?
We should tell you that MartinLogan indeed has a very substantial number of customers in tropical regions of the world. Our speakers have been serving them nicely for many years. This concern may have come from our earlier design of speakers, which were charged continu- ously. Since 1993, all of our speakers have been designed so that they only charge the panel while music is being
played. This improvement has made a tremendous dif- ference in the consistent performance of our product. There may be a little more maintenance involved in humid regions when not in an air conditioned envi- ronment. Simply enough, the concern is to keep the electrostatic panels dust free. Humidity will combine with any dust on the panel to make it slightly conduc- tive. This will result in a slight pathway for the charge to leave the membrane of the speaker. The solution is simple. They only require occasional vacuuming with a strong vacuum hose.
How .do .I .vacuum .my .MartinLogan .speakers? Vacuuming will be most effective if the speakers have been unplugged for six hours to twelve hours (or over- night). You need not worry about the vacuum pressure damaging the "delicate" membrane. It is extraordi- narily durable. Dirt and dust may be vacuumed off with a brush attachment connected to your vacuum cleaner, or you may blow them off with compressed air. When vacuuming or blowing off your panels do so to both sides, but focus the majority of your attention on the front of the panels.
Should .I .unplug .my .speakers .during .a .thunderstorm? . Yes, or before. It’s a good idea to disconnect all of your audio/video components during stormy weather.
