ROOM DAMPING - CHOOSING THE CORRECT SUPPLIERS AND MATERIALS


I am at the point where room damping is a real issue.  My listening set up, by necessity, is the "room acoustics from hell" 15' X 55' with the front LR speakers placed facing the 15' and 12' ceiling.  Wood floors no carpet (dogs), All walls covered in drywall.  
The B&W 702 S2's are notoriously bright - in my experience, that is also true. 

Anthony Grimani (YouTube/Audioholics ) recommends 15 - 20% room coverage with alternating damping -diffusion panels.  SonitusUSA is out of stock on the panels that dampen the higher frequencies.  
I need to get the harshness / brightness under control as well.

Here is my Question: Which manufacturers should I be looking at for sound damping and sound diffusion panels?  


Building and improving my gear as I go (current hardware below):
AVR 7.2 / 2 channel music setup:
Denon AVR3700H (105 watts)
Rotel 1590 2 channel power amp connected through the Denon pre outs.  
Bowers & Wilkins 702 S2 (left right) speakers.  
Bowers & Wilkins 802 LCR (center power connection by Denon amp)  
Paradigm Phantom V1 LR Side
Paradigm Atom V1 LR Rear
SVS PB-1000 - YAMAHA YST-SW315 powered subwoofers
Sony 85" TV 

Lumin U1 Streamer
Denafrips Pontus DAC (R2R)

Hey sbank 
Spencer -  Rearranging the room makes perfect sense but… I can’t do it.  (Never hire an architect with overly contemporary wild ideas.)

So the left side wall is 11’ from left front speaker and brick chimney is 15’ from right front (wall 27’)
Going now to the Asylum site to learn how locate the first and second reflection points. 
It may be I might also need to use additional movable panels for rear and sides.

that's easy...just get a mirror(floorstanding or with a helper to hold/move it) and a flashlight. Sit in the sweet spot with the flashlight. Move the mirror along each wall and aim the light at the mirror. When the reflection of the flashlight lights up the tweeter on the same side of room, that's the first reflection point. Place your panel where the mirror is. Repeat the process looking for the reflection of the left speaker on the right wall and vice-versa; that's the 2nd reflection point. Place another pair of panels there. Cheers,
Spencer

I use RealTraps in corners, GIK for ceiling and RPG for diffusion and wall/ceiling corners.  I had it tested by a sound engineer.  Since the pictures were taken, I swapped the diffusion to the back wall and the RPG Bad Panels to the front wall.   

When I bought the acoustical material, GIK and RealTraps didn't have the corner bass traps they do today.  I probably would have used them, but it sounds great the way it is.  Call them for advice.  I used suggestions from all 3 companies!
