Bernardo,
I've sent you a pm. I know of somebody who owns a pair of Duke's Jazz modules in Chapel Hill.
Duke's Planetarium Beta's would probably easily compete with the Beethovens from my experience with controlled directivity loudspeakers.
Best of luck in your search. If you are still looking for an audition in the fall of 2011, look me up and I can help. Unfortunately this next year will be very busy for me and I'll have to hold off on Geddes auditions in the meantime.
Best,
Anand.
