Features and General Questions for Electrostatic Speakers

« Back to Support Home

I think my MartinLogan speakers have developed a problem. The right speaker is hissing even when the amplifier is disconnected.

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. You can get the same benefit by simply unplugging them whenever they are not in use. A power strip is an easy way to do that.

Uncompromising performance. Unflinching accuracy. Unwavering reliability. Harnessing the myriad technical advantages of electrostatic principles to recreate sound in its truest form—this is what MartinLogan is all about.
