Experimenting with Speaker Room Placement


Hi - was having troubles with my room, which is 12 wide by 20 long, so logically I was thinking put the speakers on the shorter 12ft wall and sit back about 11-12 feet so I'd have more room between listener and the speakers. But tried my PSB towers, PSB bookshelfs, Bose Bookshelves, JBL bookshelves (and tried PSB sub with each) and that placement was always boomy bass and fatiguing sound. Just didn't sound right. 

So I tried setting up speakers on the long wall, the 20FT wall. It looks odd since I'm sitting pretty close to the speakers, about 7-8 Ft vs. 12 Ft, and the speakers are right up against the wall, and my listening chair is right up against the opposite wall. But it's more listenable, and bass seems tighter. Both the floorstanders and the bookshelves sound better. 

I'm still trying to purchase a new pair of speakers for this room (the other speakers mentioned were just borrowed from other rooms and from my home theatre setup). 

So wondering if others have experimented and found the long wall is better? It's more of a near field listening experience and looks odd having large towers that close to the listener. Would this position get fatiguing after a while? Should I treat the back wall with something since that wall is right behind my ears? What speakers are you using that seem to work well in this type of close listening setup?  If I place the speakers back on the shorter wall, is my issue that I need bass traps along the shorter wall to tighten the bass? 

Thanks very much for any guidance!

Oh, no, not again! This topic has been discussed to death. Please use the search function!
Okay I do appreciate all the suggestions I realize it is a topic that has been discussed before even yesterday was an interesting topic about possibly bipolar or omnidirectional speakers like the ohm Walsh that might be a possibility in my room as well. 
Pulling the speakers out from the short wall at least 5 ft helped with Clarity but those side wall Reflections are still getting me 
Something to try to minimize the sidewall reflections. Toe in the speakers until the axis of the speakers cross well in front of your listening position. If that doesn't effect a reduction in sidewall reflections, your problem might just not be sidewall reflections at all. If it does help you might consider what you might do, acoustically speaking, to reduce the reflections. 
closer to long wall down to half-foot is fine -- wall rug behind them will kill reflections from back wall. 
i'm 6' from my Aerial 10T and they're 7' apart.
I liked it more than speakers 6' apart and I'm 8' away.
I prefer distance between speakers to be larger than distance from speakers.
Room is 14x17
