There is a speaker builder that posts here. His moniker is Audiokinesis. He has a speaker called the "Jazz Module" which uses the waveguide technology. As far as being revolutionary or underground you can define that. When I listened to them they sounded very good. Duke is also a very good human being.
Looking for the next best thing? Underground welco
I would like to know if anyone can recommend any loudspeakers that are so called off the beaten path. I am very aware of the Zu and Gallo and B&W and JmLab and Vons and Ushers and Hyperion etc, and would like to know if you could recommend the next best thing in technology advancement that most people have not written so much about. Its obvious that the flavor of the month club is always writing about the current best thing. I am looking for interesting new technology that is not so written about and your underground types that may be the next greatest. Thanks>> Bill
