Speakers for the real world. Placement problems.

I am currently looking to get a speaker in the mid-tower region with nothing smaller than a 10" woofer even Dual 10" is better.
Must produce big soundstage and Low Freq.BASS on their own and Have the battle tank build quality. Cannot get away with any subwoofers at this point so that is why those attributes are very important and the most Important is VERY FORGIVING ON ROOM PLACEMENT!!! They will be in a 14' x 18' Space and several little obstacles with door placements and what not. So I kind of have to throw the 1/3 rules in stereo imaging out the window(pun intended). Goal is filling the room with good full sound. I guess a pretty efficient speaker would be a fine idea, maybe 92db and above. $2000 used is the limit. Currently running the Odyssey amp 150watt per channnel and an Audio research pure tube pre-amp 1960's amperex tubes, all equipment and cables built within the last 5 years. I'm not too interested in the Ear bleeders like cheaper Klipsch I prefer big power and sound with very smooth midrange and highs even at higher power levels. Mostly Rock and Pink floyd
big stadium kind of stuff listened to ALMOST always on VINYL. Thanks Guys and Girls!
