Here's how electrostatic speakers work. Unless you're an audiophile, you've probably never heard of the electrostatic loudspeaker. Electrostatic loudspeakers are pretty hip in the audiophile World because they exhibit levels of distortion one to two orders of magnitude lower than conventional cone drivers in a box. Electrostatic speakers generate vibrantly crisp highs and astonishingly clear mid tones which makes it easy to understand why audiophiles love them. A set of electrostatic speakers will breath new life into any old CD. I guarantee it. So, if electrostatic speakers sound so good, then why don't we see electrostatic speakers everywhere as opposed to conventional speakers? Well, the reasons are ten-fold. Cost, complexity, moisture issues, fragility, the requirement of an additional sub woofer... It just goes on and on. But... You know what's really cool about Electrostatic speakers other than their awesome sound? How they work, and that's what this video is all about.
