Brad,
I've read what you've written about your Odeon speakers! I was especially interested in how natural you've found the Odeon's to sound accompanied with inner-detail, delicacy, correct harmonic tone, color & timbre --my paraphrase of what I think I remember you saying, yet amazingly enough you also found the Odeons to be free of any "horn coloration(s)!" Since reading what you've written about your speakers, the Odeon brand of horn speakers was placed very high on my list of speakers I'd go out-of-my-way to personally audition!!! I can only hope the day arrives when I'm able to do so...

Odeons are the first horn speakers I ever heard that were free of the usual horn colorations. They are not the only ones now that I have heard that pull this trick (Acapella does and so does Lansche...all German). Interestingly, they are all spherical horn designs rather than the usual exponential horn or Tractrix designs I have seen. Of course the best I ever heard is the Living Voice Vox Olympian/Elyssian but this is mega buck range.
I have also heard some very good Western Electric speakers and replicas and they sound great but ultimately a bit too colored IMO. The resonances of the horns are just too obvious.
This backloading seems to take care of a lot of this issue as the midrange is still basically direct radiating and not in the throat of a horn, however, I do not like the highs on nearly every single driver Lowther, Fostex etc. driver and I have heard all the best except Feastrex...including Voxativ and Fertin etc. That is why I like the two-way concept with 1st order xover from Odeon...use the main driver only up to a couple KHz with gentle blend to a nice horn loaded tweeter. Tune Audio from Greece makes a speaker very similar to the Rigoletto that uses a Fostex in a backloaded horn with a Fostex horn tweeter as well. Also about 93db and an easy load and moderately sized.
Now the big hybrid Odeons (hybid because the bass is a special vented box rather than horn loaded) are true three-ways and they too are free from coloration and I think it has to do with the fact that they use a normal cone driver (Audax Aerogel) in a horn without extreme compression. That plus a really rigid solid wood horn...far better than plastic or metal, IMO.
The other thing is that the compression is not so extreme and we are talking 95db speakers rather than 100+ db speakers. Their No. 32 and 38 are among the best speakers I have heard...my La Bohemes are right with them down to about 40hz but don't do the last octave.
There were two pairs of Odeons available in Minnesota not too long ago. One was a beautiful pair of my La Bohemes and the other was a pair of the equally beautiful La Traviata (not the one reviewed in Stereophile but a true horn) that is one size smaller (8 inch vs. 10 inch main driver and a bit smaller tweeter horn). They wanted 3.5K for the Traviatas (14K new) and 6.5K for the La Bohemes (20K new). If they hadn't been overseas for me I would have probably snagged the smaller pair for my downstairs system (it is the only ones I have ever seen on the internet). I have only seen one other pair of La Bohemes so these older Odeons are very rare. The Riogletto is quite easy to get in Europe and for relatively low money.
Brad that $20K pair of Odeon La Boheme speakers are still for sale in MN for $6.5K! Amazing huh? If I had $6.5K available, I'd own those Odeon La Boheme speakers already...
