Thanks BDP24! You saved me some typing, totally agree! Using the balance control to compensate displacement of speakers, wow! that really hurt my audio soul, thats like using one bad to fix another bad.
Maybe you can move the speakers to another wall for symmetrical positioning??
Follow Ups:
Knock out a corresponding-sized notch behind the listening position, but on the left side. I agree with everyone here, you can't fix a problem with another problem, but what if you balance out the problem by doing the negation of it? Would that not be 1 + -1?
Maybe there already is such a notch. The OP didn't say.

LOL, you really had me thinking about that for a few seconds!.......... but no, that won't work, its all about the energy thats fired towards the front wall(behind the speakers), you must have a symmetrical situation there, thats actually THE most important wall of all, side walls + back wall(behind listener) have less influence. But I must give you a A+ for original ideas!
"... but no, that won't work, its all about the energy thats fired towards the front wall(behind the speakers), you must have a symmetrical situation there, thats actually THE most important wall of all, side walls + back wall(behind listener) have less influence."
Long ago, I had some interest and concern about sound emanating from that wall behind my Tympanis, and hung a batch of mattress pads on the backs of the speakers. I was unable to discern any large difference in the resultant sound. I concluded that the front wall is not as significant as many enjoy saying.
I've experimented with absorption behind them. Ended up with pinpoint imaging that was impressive, but after a while I got tired of the unnaturally "dry" acoustic and went back to rear wall reflections.
Mattress pads absorb as opposed to a wall that will reflect, I can only imagine that your Tympani's are placed well away from the front wall which will reduce the influence of reflections, that might(?) explain the minor difference you experienced, or your front wall was already covered with absorbing material?. In normal room set-ups moving speakers towards and away from the front wall will have a large influence on bass volume and image depth, the influence of side walls is much smaller and the back wall basically only comes into play if your listening seat Is in it's proximity.
I actually fire my mg12's across the diagonal, but not a "true" diagonal. I've used speakers that way for years. A reviewer for Stereophile used to always use this approach, and also did his own measurements in that setup. I forget his name. I tried it, and I liked it.
I think it helps I prefer a closer seating to the place of the speakers, like 6 ft or so. I really am just "placing by listening" when it comes to listening spot and speakers. Pure amateur ;)
Also helps to have a decent room that is basically just the speakers and the stereo and the chair. I lucky.

Must admit, I've tried all kind of weird stuff with set-up's but never diagonal, but why not? you can still create a symmetrical situation for back firing energy and improve reflections(waves won't bounce straight back as in a standard situation) at the same time.
Seated close is the only way to go, has so many advantages, one being that you're actually listening to your speakers instead of the room! and of course you place by listening, you can measure all day but in the end it's your ears that have the last word on positioning, nothing amateurish about that at all.
You can always check your final positioning with a mono recording, and not just a voice or single instrument but multi instrumental, sit yourself dead centre and dial the speakers in to the point that all players are crammed together in the tightest centre image possible, your centre image should be no more than a foot wide.
Oh absolutely. Mono is the secret sauce for set up. Mono itself makes for a good listen once you get into that mood. I find the mono almost has a depth to it sometimes.
"Today" Jefferson Airplane,mono version is pretty awesome. So is mono Sinatra. His voice makes for a great reference.
Tom Norton was the reviewer. He gave reasons why diagonal is worth checking out, but forget what review he laid it out.

I'm of course familiar 'O'l Blue Eyes' but all I know about Jefferson Airplane comes from the Coen Bros' movie, 'A Serious Man'. :-)
Norman, A Serious Man is one of my favorite Coen Brothers films! (another is The Man Who Wasn't There, starring Billy Bob Thornton). If I hadn't been married to a Jewish woman for 25 years (her Father's name was Norman ;-) I would not have understood it nearly as well.

I'm also a Coen Bros. fan and have everything of theirs which is on blu ray. The Man Who Wasn't There took ages to get released on blu-ray in the US. (Of course I have on DVD.) I was forced into buying the blu-ray from France, but now have the US product as well.
Don't neglect to watch one of their biggest hits,'The Big Lebowski'! In that movie the character played by John Goodman married a Jewess and then started behaving as if he were a Jew. Naturally the Coen Bros. had a lot of fun with that.
Oh yeah Norman, love The Big Lebowski. I have a lot of their movies on DVD (I'm not a hardcore videophile; DVD is good enough for me, and cheap!). I think O Brother Where Art Thou is their best known movie, and is a lot of fun. It's great soundtrack was supervised by T Bone Burnett, whose Truth Decay album I love. As a bonus, it's recorded sound quality is almost audiophile level, really good. T Bone was a cast member of Dylan's Rolling Thunder Revue, and has produced a lot of great albums, including some by Elvis Costello and Los Lobos---Eric.
