The Tonians are one I would want to consider in your case.
Larger performance tweaked Klispch La Scala, Horn, or Cornwalls are another.
A lot of people like Zu. Also one I would consider.
The best speakers I have hard that fit your bill were a pair of custom GOTO horns, but cost of these is probably out of your range and these are not easy to come by.
Shindo Latour is another I would want to audition if I could afford them.
maggies or Quad ESLs are also options perhaps assuming your tube amp has some power to drive these less efficient but generally tube friendly designs.
