Electrostatic Technology

treVolo S uses the same Electrostatic Speaker Technology that is typically reserved for high-end speaker systems. With a distortion rate that is only one-tenth of the rate of conventional speakers and no cabinet resonance, electrostatic speakers deliver natural and spacious sound.

* Conventional speakers have a distortion rate of 10% while electrostatic speakers have a distortion rate of less than 1%.
