All ESL's are humidity sensitive. The higher the humidity the more conductive air is. When high humidity levels are coupled with high volume you can get panel failure. At high humidity levels the air is much more conductive and the electrostatic field breaks down. Sparking then occurs. Minimal sparking can put pin holes in the diaphragm. It can ruin the diaphragm at high spark levels. Keep them in a low humidity room or don't play them at ear shattering levels when the humidity is high. I have owned ESL's from various manufacturers for more than twenty years. In that time I have never experienced a panel failure.
