Looking for wider soundstage

Ook not getting pic thing so will describe. Room is 22x17x8. Speakers are along the 22’ wall. Seating position is 15’ from speakers which are 13’ apart. There is a window behind listening position with a curtain. Floor is thickly carpeted. Behind speakers is drywall wall. There is no extra sound enhancing furniture in the room. That’s really about it. I will post a pic when I can but hoping the description will help. Thanks. 

Well I got one pic posted in my profile. Not great. Sorry. I think I can get a wider one later. 

Looking at photo. Again nice system.

I would have to say your setup is the limiting factor

13’ is too big a triangle… typically you would want 6 - 9’ between the speakers and the listening location. So an equilateral triangle. Also having your equipment in between your speakers and no absorbent material behind your system is probably a problem.

Honestly, it is not uncommon that systems are limited when put in common areas. If you can’t modify your setup. Is it possible to use a smaller dedicated place wher you can put tube traps and wall hangings where you want? If you can do what is needed you can do some amazing things.

More photos more better.

Added a couple more pics. Also from middle of left speaker to middle of right speaker it is about 7’ not 13. Listening position is about 8.5’. Not sure if I can get my own room or not. Would love to though. I might be able to put up something temporary behind speakers and behind electronics though. Is speaker height high enough or does it need to go higher? Thanks. 

Yeah, I know it's tough getting a truly optimal placement for a system. I feel for ya. I mean, when somebody wanders into the kitchen in the middle of the night for that bowl of Rice Crispies, you don't want them going nose-to-nose with a soft-dome tweeter.
