Are there any loudspeakers with a wide sweet spot under $10,000?

Gallo Ref I & II's have 270 degree tweeters. They need to be out in the room. HUGE sound stage. $1500-2000.

MBL's are 360 degree. You need monster amps also. You might find some just under 10K.
Check out the Dali Euphonia line. The website highlights some of their sound principles, one of which is building speakers with a wide sweet spot - http://www.dali.dk/display_content.php/INT/widedispersion.html
