Hello fellow AC members.
I have decided to treat my living room soon now that I have some new tower speakers on their way soon (Ascend Towers). I plan to order several sheets of the OC703 in 2'x4' (2 inch thick) pieces and make wooden frames wrapped in GOM fabric. I am pretty familiar with building the frames and etc since I constructed a theater room a while back using the same materials.
I do need some suggestions on size, placement, etc. First off, after doing some research, I assume the OC703 2" material will be sufficient for treating the 1st and rear reflection points (which are my priorities)?
Secondly, I will post pics of my room and need suggestions on placement and what size panels I can utilize (smaller the better).
I imagine I need to do the mirror trick and sit in my listening position and slide the mirror along the side walls. How do I determine the rear wall reflections? By looking at my room pics, you will see the back wall is a good 15ft behind my LP(couch) but there are two half walls that cut into the room on each side of the couch just behind me. Suggestions?
Also, ignore the Christmas tree, normally that is gone and the couch next to it is slid closer to the fireplace.

Looking to rear again at right corner (same side christmas tree is on)

Looking to rear corner, left side this time.

Thanks,
