Are there guidlines to fix strange room acoustics?


For instance, if you're center image is off center can you fixit with moving just one speaker in, out, back, forward, more or less toe?

Also, what if bass is noticeably louder in one corner, and you can hear it from your listening chair and if you get up and stand in that corner, the bass is louder in that corner vs. the other corners. My listening room is set up equally on both sides, so I can't figure out for the life of me why the bass is collecting in one corner. I do have a few bass traps and have moved them all over and it doesn't change...

Should I try setting up my system with the center stage centered in a corner of the room? Should I just move it into the unfinished basement with exposed concrete floors and exposed plastic lined insulation? Theres plenty of room down there, but its very "alive" and echoey (is that even a word??).

Why not, it worked for me ;-)
Try the diagonal set up as it tends to neutralize room nodes. However, do not set it up such that the center stage is in a corner. The diagonal should be off axis to a corner.

Even though a room can be set up symmetrically this doesn't mean all things will be equal. For example your speakers do not have to be symmetrical with any room boundaries, nor do you have to sit in an equilateral triangle set up.

If all else fails at least you still have the basement.
Buy a Raymore & Flannigan leather recliner loveseat coach. It fixed an annoying room bass node problem. Plus it doubles as a back messager because the absorbed bass energy vibrates the whole coach. :)

IMHO, if the center image is off with the "room set up equally," I would definitely rule out any equipment issues first. Swap L and R speaker connections on the back of the amp. The stereo image will be reversed, but the problem should not change if it is the room. You could also swap the speakers to rule them out.
Tls, it's not the equipment. Been there done that.

I might just try the basement, when i have a bunch of extra energy
Even better, finish out the basement, drywall etc and make it into a dedicated listening room :-)

Good Listening

Moving Speakers around always changes the sound stage...keep trying ,you might get lucky. 
You gotta tune the room / sys ... a symmetric placement will likely result in an unbalanced result.
Simply pick up four 4" panels / hybrid or absorber and start to damp the room ( also placement ) until it sounds better.
Guidelines yes but ... some rooms / gear are more complex.
