Dale Harder seems to know what he is talking about, and he hand builds all the speakers himself.

There is a British company which has received come good reviews "Omnimon"

I tried contacting rountree, but no reply, donno what the economy has done to a lot of small business.

There is an Italian company which has principles similar to Duevel, the name of which I can't remember for the moment

Last but not least Sony has a new Omni if it every interests you
