Has anyone ever heard these speakers by Volti Audio?

Greg Roberts of Volti is a straight shooter....tells the facts. Likewise Gary Dews of Border Patrol mirrors likewise. I have never heard the speakers outside a Hotel room but they put you at the performance in those crappy rooms so my guess it gets much better with an acoustically treated room.
I owned Gary Dews BP amp. fully loaded 300B driving some past owned Edgarhorns and can tell you they would make a lot of speakers sing. Your amplifiers of choice would have to be very quiet and special to get what you paid from the Voltis but is true with most all speakers. Also would guess the imaging would be my question in a larger room. Would want to hear them in a better environment than the show before I would drop the cash if it were me.

There are plenty of Interesting points here regarding the mid range preferred by Uccello and Vittora going different ways.I would love to and will one day trot off to the UK give the Uccello a listen. Its great that there are small companies keeping the horn flag flying as despite all the anomalies and serious quirks horns, like our ears are the best for music, my opinion, naturally. Wonder if Uccello will ever come to the US to a show or find a distributor, such as High Water Sound? Why not try a bigger mid range cone and larger flare rather than a 2" mid range cone? which seems to be the vogue. Cost maybe?

I normally don't post but have to chime in on this thread. I'm stilling laughing from the previous post about "prying them from his cold dead hands". I have used that exact same wording in talking to Greg at Volti. I have the Alura's and absolutely love them. I first heard the Vittora's at Axpona and fell in love but quickly realized that they would not fit in my 13'x13' room and more importantly I couldn't afford them. But they sounded great!  So Greg suggested I go hear the Alura's in another room. So I did. And bought the speakers at the show. 

Since my room is small it took some dialing in of the bass (these things do bass!) and lots of moving of the speakers. And these things are heavy so it was a chore. But I regret none of it. I love these speakers. 

I travel A LOT and have visited lots of high end audio stores so I get to hear lots of speakers. I have heard nothing that comes close to making me want to change. And I've listened to very high end speakers. 

Greg is first class to work with. I can certainly recommend Volti.

The devil's in the detail ;)

The Uccello’s are build to order, and as is Mr. Mears has a waiting list and will concentrate on current orders until taking new ones. I know that he recently sold his own (first-build) pair of Uccello’s to a fellow in the UK, so maybe he could assist with an audition arranged through Mr. Mears. Should you venture to Denmark I’ll gladly give you a demo of my Uccello’s (with or without the aid of subwoofer, at your choosing) :)

I wholeheartedly agree. Meeting the speaker builder himself with no middlemen is a treasure if one cherishes being confronted with the true passion - insofar this is embraced by the man himself :) I read of the Uccello’s online by some mere chance (actually my initial interest was in Mr. Mears’ rebuild of the Tannoy Autograph cornerhorns), mailed Simon, then called him and arranged for an audition at his place in Brighton, UK. I then ordered the Uccello’s, waited some 3 months until they were finished, and picked them up by myself (with the help of a friend) after a long van-drive to Brighton and back (we wanted to avoid any freight companies for specific reasons). All the while my speakers were made I was sent pictures and had a continuing correspondence with Mr. Mears on design options, the process, etc. (others would simply order the speakers, and not be heard from until their pair of speakers were finished - whatever one chooses here). Having been fortunate to acquire the Uccello’s and experience the whole process of their making (and beyond) is something I’m grateful for.
Properly designed and implemented horns offer something quite unique, to my mind as well. Coming about this could be a many-pages long post in itself..

Wonder if Uccello will ever come to the US to a show or find a distributor, such as High Water Sound?

This will not be the case, I’m told. A distributor would also send the retail price north of its current listing with a significant margin, which Mr. Mears has no interest in.

Why not try a bigger mid range cone and larger flare rather than a 2" mid range cone? which seems to be the vogue. Cost maybe?

Bear in mind that the Uccello’s midrange driver sports a 5" diaphragm (with a 2" exit), which to my knowledge is larger than any known midrange compression in production today (expect of course its design origin and inspiration, the RCA MI1428 field coil unit). A larger horn would be easily attainable, but then of course be a different design than the Uccello’s.

@phusis  I'm new to horn speakers and your post is truly educational for me. Thank You! A trip to Brighton and a meeting with Mr. Mears would be a really nice add on to a future planned Vincent Brient and  ~ Mont Saint-Michel meeting.
