Electrostatic Speakers

MartinLogan is most famous for their electrostatic speakers (ESLs). I remember many years ago hearing their full-range model and was astonished at the transparency. Since that time, they have produced ESLs of varying sizes, and in "hybrid" form, meaning that a cone woofer takes care of the low frequencies, which smaller ELS panels cannot reproduce. When home theater became a prominent market, they released the Stage, which used a dome tweeter, ESL panel for the midrange, and cone woofers. The newest iteration of the Stage line is the Stage X, which has a thin film tweeter (called "Folded Motion" by MartinLogan). This type of tweeter is part of the flat panel family of speakers, which includes ESLs, Ribbons, and Planar Magnetic speakers. So, with the Stage X, the high frequencies and midrange are now handled by flat panel technology.
