This is an oldish thread and I hope you have toed in your speakers or otherwise to your satisfaction by now.
My room is rectangular with a cathedral ceiling. Looking at the speakers I have alcoves. a display cabinet and a bookcase running down the left side and wall to ceiling glass doors running down the right side.
Took me quite a while to figure out to keep the left speaker almost straight on, maybe a degree toed in. The right needed to be toed in about 5 degrees with 3db of balance applied to the right.
Keep tweaking your speakers until they sound great, no rules.
