A intuitive long shot a couple years ago from Craig's List satisfied my long search for main's: A church had a pair of mid-1980's Yamaha SX-1 cathedral organ monitors that turned out to be the best self-powered main's I ever heard (after a few hours of old school re-conditioning).
Each has 320 watt SS amps, 15 inch bass drivers in the lower unit's, and three independently facing upper units (forward and L/R at 30 degrees), each loaded with one 6 inch mid and 2 ultra-smooth tweeters. I adopted them for keeps after auditioning the speakers' "voices". They're perfect for a 30 x 30 room.
