If you made a tour of audio specialty dealers in the USA, you would be hard-pressed to find any full-range electrostatic or ribbon speakers—except for Magneplanars. Despite the market trend away from big speakers, Magnepan has survived (and thrived) because no other technology provides better sound for the money. And it is made in the USA.
