Here's another update. Lots of photos of the control room panels.

This is the diffuser for the back wall

The front wall will be mostly reflective and just a bit of absorption to fix some 200hz issue we found in the preliminary measurements.

Here's a detail of the front wall

The diffusers for the left and right walls have also arrived. A whole stack of them 

Ahhh nothing like powertools 

The structure on the right wall and some of the paneling is already in place

And the red colored panels are awaiting its turn to be placed on the walls, they actually look a little orangy in the photos but they are really Red! 

Hopefully tomorrow will have more to show.
