Room Treatment? How important is it to treat the wall behind/between the speakers?

@macg19,

Your equipment is very nice and room seems to have good capability. First thing I would do is to move your speaker at least 3 more feet into the room (if possible). Adjust the seat position to close to an equilateral triangle, keeping all vertices between the speakers and speakers and you the same. That will also improve direct sound from them vs room reflections. I use lots of diffusion in my room (all walls and ceiling). You can check the pictures of my room in my profile. They are not updated after my latest diffusers and bass traps inside the closet were added, but you'll have an idea. Best of luck, 

Thank you all for the advice. I could move the diffusers on the left side wall to the front wall and use an absorption panel instead. The right wall (bay window) already has an absorption panel + drapes. 

@kellerjr01 Thanks! I have tried the speakers 5ft from the front wall but the bass gets boomy + it puts the listening position too far into the living room.

I plan to add something like the GIK Soffit Bass Traps floor-to-ceiling eventually but there are other priorities for $$$ atm. 

My understanding re: diffusion panels is that  their effectiveness depends upon the size of one's room since they're not helpful in small ones. As to what constitutes a small room...GIK and other experts can guide you. Good luck!

@fthompson251 I sent pics and dims to GIK and that is exactly what they recommended.

@kellerjr01 I took your advice and tried moving the speakers out again - front baffles are now 5 ft from the wall now. I could go another foot.

So far I like it.

I realized I had added more treatments since I last tried them that far out in the room and the listing position is fine - speakers are 7ft apart and listing position is 8-9ft now without moving the chairs.
