Horn Speaker Recommendations

I think you would be doing yourself a favor if you purchased a moderate size horn and accompanied it with a pair of the Wilson Beseech Torus infrasonic generators. They are breath taking, fast and very deep and extremely musical as well as accurate. To get a horn to go that low and be that fast is really difficult. In addition and it is no small mater with the Torus you will be happy using them with any main speaker you ever buy.

soundsrealaudio....will on Torus work?  There has not been much news online since 2007 on this item.  Are you a dealer?   How much are they now including the amp?

+1 for Volti. I was pretty impressed with those when I heard them, and I really enjoyed talking with the designer and builder (Greg Roberts) at Lone Star Audio Fest. He managed to make those speakers sound very good in a small hotel room, and they are clearly meant to shine in a larger space. I would reach out to them and you'll likely get to speak with Greg directly. If you're into high efficiency horns in that price range, I think just hearing his input directly would be worth your time, even if you go a different way. 

Wilson Benesch Torus retail for $12,900 with the amp/crossover. I am not a dealer the distributor is Aaudio Imports in Colorado. If that is too rich for you blood I would suggest a couple of small diameter subs, say 8" or 10" so they would be fast enough to keep pace with horns. 

"I understand the considerations in regards to interior decoration, but if you’re really into sound reproduction let your speakers be a main priority in the allotted space they’re given - with the adherence to form-follows-function as far as it goes, and not vice versa. As it often happens, to my eyes at least, the really interesting physical shape of speakers comes via an uninhibited accordance with their function as dictated by physics. Even a much smaller, typical slender square box speaker can be seen as an outright nuisance in a home setting because it’s just that: a tall, rectangular square box oftentimes finished in a rather sterile manner, and one that’s placed well into the room, at that."  Precisely right and  much of the speaker world, no let me restate this to 95% of the "high end" speaker world is form before function and then trying to make them to work well within the physical parameters of the pretty, avant-garde or techno-artisto box. OP wants pretty and decent sound which I can understand is the choice of most but when I close my eyes I want to pretend I am truly in one of the best seats in the live performance. I want spectacular sound and looks just don't matter.
