High efficiency speakers


I am looking for medium size high efficiency speakers. How would you compare trenner & friedl RA and Devore orangutan 0/96? Any others I Should be looking at that similar or smaller footprint and can be driven sufficiently by 8w 300b SET? Thanks

Edoir I had the Ocellia Calliope .30 Twin speakers, great sound awful customer support! PHY driver is a wonder cabinet is a DYI project at best. (IMHO)
Sksos1,
I believe Ocellia has superb products, it's disappointing to hear you had service issues with them. I assumed Samuel would have that aspect covered as well.
Charles1dad,
Sonically no complaints just a wonderful sound, quick and transparent but when I had an issue (and no fault of Ocellia) what a hassle.
In hindsight though couldn't be happier with my Acoustic Zen Cresendo speakers. Music has never had the presence and focus as with these transducers.
