Room treatment can be addictive

@tcutter Thanks! My L shaped sectional is head high & actually runs along the windows then into the room. Only one woofer is above the couch (R11’s). I had thought about free standing panels… might give that a try.
Follow up question. I put a bass trap in the far left hand corner of the room (about 12’ from the left speaker & 19’ from the right). I could use it elsewhere if not effective there. Thoughts?
BTW, your room and system is GORGEOUS!

@signaforce I think you’re partway there with the couch if it’s in front of the first reflection points for each of the speakers. if you’re saying head high when you’re sitting you might want to add some panels (2 x 2’) on top of the couch while you’re listening. Those are really easy to put away. 
 

There is only one way to determine if that is the best corner in which to put the bass trap and that is to listen there and in the alternative spaces. I imagine no matter what corner, you’re getting some benefit although there is a possibility a lack of symmetry may hurt you. On the other hand, your room is already asymmetric. Only way to find out.
 

And thank you. I can listen for hours on end.

You could also just put some large pillows on the back of the couch. Easy Peasy. Good luck.

I stopped at 30 panels.  Mostly because I have no space for more.

I started with blankets and pillows, then homemade rockwool and then bought my first GIK panels and the WOW factor kicked in. I sent my room information to Mike and purchased every panel he recommended. I am so happy I made that decision!
