I'm a dealer for "Oskar" speakers, from Switzerland, and both the Kithara and Aulos use Heil drivers (of different sizes).
Here's a link to some propaganda: http://www.tricell-ent.com/Oskar.htm
In addition to the UHF reviews mentioned, the Aulos got a pretty nice review in SoundStage in January 2001.
