Listening triangle

Really does seem to be a lot of trial an error in speaker placement as each room is so different.
I tried the Cardas method and it was different, but the soundstage was not as wide (it called for moving the monitors 4.25' from the sidewalls and 7' from backwall).
I am using a variation of it and the rule of 3rds, or 5ths or something :)

A couple basic suggestions:

Move the monitors into the room from the backwall if you can, and in from the sidewalls. Experiment from there on placement and toe in.

I settled on 5' in, 3.25' from sides, 8' apart and my listening spot is 10' from monitors (so not a triangle). Sub is behind the left speaker away from the backwall and next to the sidewall.
No toe in. Room is 15.5' wide by 26' long and 8' high with stairwell wall on right side halfway into room.

System is in my signature.
Have fun. It took me a week of playing around.
Will probably change it next month:)

Oops. Should have said my 8'X 10' X 10' triangle was not a triangle with equal sides.
I did read somewhere where this was suggested as possibly desirable, but that was just a theory.

Interesting. I had not tried sitting with my head in the equilateral triangle spot as you have. I guess my room did not really allow it with where I had my couch (and listening position while sitting normally). If I sit on the edge of the couch and lean forward I can get close to an e-triangle.

As the Cardas method also does suggest an e-triangle I gave that a try tonight. Something really kind of kicked in at a 100" e-triangle. So much that I am now considering moving my couch so I can sit normally at that distance.
Will keep tweaking.

Yes! That "something" that I mentioned that kicked in is almost like sticking your head under water in the "pool" of sound.
Bad analogy, but their is some kind of boundary that is present at the e-triangle point. You are more immersed in the soundfield it seems.
Fun to experiment with. I am seemingly liking the e-triangle more than my previous arrangment right now.
