need advice!!

Hi, everyone!

Here's my control room! It's dimensions are 5x3.5x2.8 m (LxWxH).

The red lines are a double layer brick wall with insulation inside, that are already built. The blue lines are what i'm going to build so that there are no paralel walls. The speakers aren't all at the same distance but I'll be puting delays on them, so that they all reach me at the same time.

1) What do you guys think? Is there anything that you'd do differently? ( I'm sure there is!! :-D)

2) What kind of treatment sould I apply on the wood frame walls (Blue lines)? I was thinking of putting two helmotz resonator on the side walls and a difusor on the back wall1

Thanks a lot everyone, and... please criticize!!!

The distance to your head from the rear wall will only give you 18.35 milliseconds before first reflections get to your ears - this will most likely cause some smearing of the stereo image (when you're mixing in stereo) - any time you have less than 22-25 millisecond delay it will not be heard as a discrete echo, but rather as a phase smearing/comb filtering problem. I'd stick with absorption on the back wall because of that.

Do you have access to a multi-channel delay that can do sub-millisecond values? You'll need just under one millisecond for both left and right front speakers, and less than that for the surrounds, assuming the center channel has zero delay.

What speakers are you planning on using? Some should NEVER be soffited. Also, it looks like maybe the distance from the speaker to the inside edge of the soffit is kind of short - this would depend on the speaker of course...

What is your ceiling height and do you plan to splay the ceiling to achieve a total RFZ? Do you have a side elevation drawing?

Are you also planning on using nearfields? Which ones? On the bridge, or on stands?

With those brick walls, be prepared to need a LOT of bass trapping - stiff walls don't do much for "freebie" bass trap effect.

Looks like a good start, hope I made you think... Steve
