Uneven room dimensions/reflections = uneven toe in as solution?

I done so successfully, but had the dominant speaker firing straight into the room and the less dominant speaker towed slightly more to the listening position (in my case/room).

On the extreme I used to set a pair of Reynaud Twin speakers so that I could listen from the sofa on the left side of the room.

I didn't move the stands, just towed in the furthest away speaker until the channels were balanced.

I placed tape markers on the top of the stands in order to make switching back easier.

This said, I have an unusual asymmetrical/lopsided "U" shaped room with a galley kitchen divided from the living room by a wall 1/3 the length of the space.

I need that symmetry so I couldn't live with different toe-in angles. However, you can also try varying the distance a little from the front wall. Pull the speaker exhibiting less output forward a 1/8" at a time until you balance the sound. 

Otherwise, you could try absorption/diffusion panels placed evenly at the first reflection points. There are panels on stands that you could move out of the way when not in use.

Thanks. At the moment I have the dominant one facing straightahead and the less dominant one towed in just a bit. It certainly makes things better. I will keep experimenting. I know that both speakers are putting out the same decibel levels. I’ve checked that. It’s just a super complicated room in which lots of experimenting will probably get the job done. 

Toed in. Sorry. I’m a writer, too. Sinful.

I should also mention that there’s a possibility my hearing isn’t exactly equal from one ear to the next at this stage of my life.

Just pull the weaker sounding speaker a little closer to you. Experiment with 1/2 or more. I have the same issue and 1 inch closer dialed it in for me.
