how big a speaker can you put in an 11 x 11 room?

Thanks....I presently have Virgo IIIs which do a nice job, though, i have become a huge fan of the Elipsas and the Revel SAlon2s so I have been ready to upgrade...but I dont think either will lend to the room...though I am a big fan of nearfield listening..the Elipsas are warm...in a room this small they may be a bit heavy...

so i'm nuts to be looking at SAlon2s, CremonaMs and Reference 3A Grand Veenas? I presntly have Virgo IIIs...which is basically a monitor......

this is why i love ag....good honest opinion (and fairly price highend audio/folks to buy stuff I dont use)...many sales people have been recommending many big speakers for this room. I have been an easy target as it's the only room in the house i can use a floorstander. I actually have a 20x20 room with 15 ft ceiling...but due to the built-ins in the room..and my wife..i cant use floorstanders so i have a pair peakconsult princess (just the monitor) with a REL sub which i love...so i was hoping that i could upgrade my virgos to a more lifelike, thicker sounding floorstander..obviously i have no intention of buying a speaker that will not perform well in this space..thanks for the advice....
