Sorry, I for one have never heard of the them. They look a little suspicious, though, considering there are only computer graphics and no actual product pictures posted on their web site. Anyhow, from their description, these appear to be simply planar magnetic speakers (like Magnepan) except with rigid rather than flexible diaphragms. These types of speakers are very inefficient and require lots of power to reach even moderate listening levels. Thomas
