Best speakers for 3 cord rock and roll

Thanks for all of the great recommendations. I actually have a 1960's juke box at my cabin and listen to a lot of old stuff on the weekends. It has tubes and does sound better in mono than in stereo!
I think I may be leaning toward the horns just because a lot of the stuff was recorded in mono thru tube equipment. I did check out the Horn shoppe, but can these little things acually be that good? My listening room is 14x20 with 16' vaulted ceilings and a real open floor plan. Actually the best place to put speakers are in the corners so the horns may even produce some bass.

Rockadanny - I'm really interested in what you hear in the new room since this about the same size as my room. If you can, listen to some old british rock to see how the recordings from the 60's sound. I'm located near Ann Arbor Michigan so it is doubtful I will be able to hear the horns unless I buy them.
Thanks

Thanks to everyone for the recommendations. I'm now going to visit some shops and take a listen. I'll keep you posted as to what I hear. I'm still interested in the little horns from the horn shoppe so if any of you hear them put a little rock into the mix for me.

Rockadanny, I think I'm sold on the horns since I live in a condo and can't shake the floors with the big stuff. I'm not sold on the tube amp since the system will be on about 10 hours a day at a low volume and I don't want to have to replace the tubes. I'm thinking about a small SS amp with good bass. Any ideas?
