Large sweetspot


I am in the market for new speakers for a my largish living room (20X30 w/ 9' ceilings). We expect to entertain in this room so I would like speakers that sound good over a wide listening area. I would like them to be close to or full range. Other priorities would be NOT bright or fatiguing, efficient enough for modest tube amps, and attactive. My budget is about $4K and I would consider recent model used speakers. I know I may not get all of my wish list in one package but I would like to hear what people thinks comes closest. Thanks in advance.

Gallo Reference 3. They disappear totally and despite their relatively small size will carry a large room (mine is 18 x 40) beautifully. You can drive them with pracically anything -- I'm using 12 wpc SET monoblocks. Hard to beat at $2600/pr.
Klipshorns. If they can't fit then Belle Klipsch. You can't get much more efficient (104 db per watt) and it can fill the area without any problem--even with a 3 watt SET amp.
The Bose is an intersting suggestion. While many audiophiles despise Bose, I have heard them sound pretty good. I heard a swing band using them in a large hall recently. (at least they looked like 901s. Do they have anything for pro use that looks the same?) Up close, they sounded quite harsh, but in the hall, they sounded amazingly good. The horns sounded incredibly rich and lush, with the kind of vibrance that I could hear if I stood right in front of the band to hear the direct unamplified sound, and the highs somehow stepped in line. However, the dance was in a very large hall, and I had to be at least 15' away for them to sound good. I suspect your room is probably not big enough for them, though.
