You're looking at the prototype Welborne Labs Cogent Field Coil horns. Now, you may look at the picture and not truly appreciate how huge these horns really are. Try almost 7 feet tall and 3 feet wide. Someone said they were just a bit too big for the small hotel room. No joke, you practically had to sit inside the horn to listen to them. Welborne did try to get a ballroom for their demo but, alas, only the crackerbox was available.
Needless to say, it was a miracle they got the speakers in the room in the first place. Also shown are the Welborne Ultrapath BP battery powered preamp at $1700 and the 45 Star Chief monoblocks at $2390. A Carver sub took over below 60Hz.
Maybe next time the hotel will be kind enough to lend their atrium for Welborne's demo. Here's to hoping.
UPDATE: Yeah, maybe the dimensions were a touch over-exaggerated. Dimensions are as follows: total unit 69" high, bass horn 33.5" wide, midrange horn 32" wide and total depth 43". Thank goodness they didn't bring their horn subwoofer -- 120 cubic feet with an 18' path of front-loaded power.
