Assistance with room treatments


I would like assistance with room treatment products.  There are absorbers, diffusers, and combinations there of.  Materials include foam, polyester, fiberglass, and wood.  Some are cloth wrapped.  Thicknesses include 0.4, 1, and 2”.  Then there are also bass trap cylinders and corners.   What is your experience as the best design and manufacturer.  My system and room is listed in my profile.  
I have never had a dedicated listening room.  My living room as served as such.  The wall unit hiding my components is necessary to assure an acceptable WAF.  The only good thing about the wall unit is my bourbon collection is a few steps away from my listening chair.  For critical listening sessions I place a cotton/wool comforter over the wall unit.  I fold or flute the comforter.  This provides very noticeable changes in timbre reducing HF glare reflecting from the glass surface and increase stage width, depth, and ambience retrieval as will as improving 3-D imaging.  I am considering three 2” cloth covered fiberglass absorbing panels (48”x24”) and a cylindrical bass trap for the right corner by GIK Acoustics.  Note the room vents to the entrance hall and stairs to the right and dining room L to the left so bass standing wave cancelation and reinforcement has not been an issue.  Please provide guidance on by path forward and indicate if you believe I will obtain benefit from the plan.

I would suggest contacting GIK  or  Music City Acoustics for advice and information. That's their business and they understand complex situations. If you can use REW to measure your room, both will analyze it and provide advice and materials.
