Has anyone ever heard these speakers by Volti Audio?

I have the original Alura, which was before the midrange horn was made vertical . Looks a lot like a Klipsch, but on steroids. Sounds great with Low powered amps, or powerful amps. I have upgraded all components to current model, as Greg has made some big upgrades since the original . Beautiful woodwork . 

Love to get home from a stressful day and listen to them! As long as I own a room large enough to accommodate them, they will stay. 

I do have to say they are horns, and you can locate the tweeters while listening to some music. Dispersion not as wide as other tweeters. I have mine set up on a short wall, but Greg sets his up on the long wall.

Vittorias are supposed to be on another level.

That is interesting! The first big upgrade I did was replace the B&C 2" horn driver with the BMS 4592. Greg Roberts used the B&C ×××50 at the beginning but changed later.

The B&C was good but colored. The BMS was a huge improvement in opening up the midrange
to my ears. Night and day difference. 

Yes, implementation is the key. I did not mean to imply the Uccello was colored, just that the Volti with the BMS was better, to my ears. 

I also read where one person, when changing from B&C to BMS, on the Volti, sent the BMS back, because he did not like the sound. 

That's why I find it interesting.
