room size question.

@dalims4 

 I'm in a 16.5 x 32' foot room using the front half for music.

which is a lot bigger than the room i have , which is 11 x 12.        

@curiousjim 

speakers are facing straight.   i did try toe in when i was setting things up a year ago in this room and tried it again just a little while ago.       didnt care to much for that.              

ears from back wall are maybe 6-8 inches

bshaw

I would suggest measuring from the center of the front of the speaker for side wall and listening distance , to the back of the speaker is ok for the front wall .

Try moving the speakers so that you have 36" from the side wall to the center of the speaker and see if you like the sound ,  you really don't have much room for moving away from the front wall , have you tried moving the speakers closer to the front wall with 30" being the closest before the bass becomes boomy and don't worry about having an equilateral triangle .  

After trying all this , maybe acoustic pannels ( diffusers-diffracters , not absorbers )

on the side walls .

you may also try the distance between your speakers , be 83% of the distance between you and the speakers.

Virtual system about your room could help.

GIK Acoustic gives free advices according to your room’s measurement

I don't want to assume what you are thinking, but so far:

you tried everything with speaker placement and seating position and volumes

room is treated

it's a decent size room

it should produce a soundstage

your layers are either not produced or something "eats" them.   

you think it's your room size. I think it's synergy and I assume it's the lack of, between the speakers and the room. (and I hope this will be the lamest, most useless comment you will get today)
