Tom Martin's Listening Room

@roxy54 They have a price list. Neither their services nor their products are cheap, but not out of line with Vicoustics and others, although GIK and Acoustic Fields provide a free assessment.   I use REW but that is not nearly as user friendly as writing a check. Not as much bragging rights either. I would not be surprised if Martin got a discount for his job, likely as did Darko with Vicoustics.

@kofibaffour There is science in terms of first reflections, not placing a QRD too close to the listening position (which it appears they did), diffusion on front and rear walls, and avoiding over-absorption. Perhaps they are able to place a panel within millimeters of its optimal position and that makes them better, but I believe close is plenty good enough for room treatment considering all of the myriad factors that one cannot address. Close will still sound remarkable.

I was surprised to see the components between the speakers. Usually, they're down the side to help optimize imaging and minimize vibration. 

Appears he has a PSI audio AVAA C214 active bass trap in the left front corner. Dude is serious.

Reflective surfaces sure are minimized. 75% of the ceiling has acoustic panels?

They aren't minimized, they are virtually eliminated. Most intriguing is that RPG does not have any diffusion panels covered with fabric so this appears to be pure absorption. Not the way you usually do a room, so I have to assume something was done custom for aesthetics.
