Rearranging control/mixing room

Mitch Connor · 10th July 2011

I am in the process of building a bunch of bass traps to begin treating my room (2'x4' traps with 4" of OC 703). Attached are a couple models of the layout. My DAW and equipment have been centered up against 'Wall A' for a while, but I'm wondering if I should reconsider this setup. Perhaps set things up against 'Wall B' or C.

Does anyone have any suggestions as to whether I should re-arrange things before I start taking measurements and begin hanging traps. Thanks for any help.

I would imagine you should be centered along wall B, facing wall B.

Perhaps move your setup around and take measurements to find which arrangement gives the best response before any treatment. This will then make it easier to get a flatter FR with treatment.

You are going to want to face wall B. Start with sitting around 38% of the room length and measure. You will find moving forward or back will further improve the response. See the following for layout.

I was wondering about Wall B, but here were my concerns with that approach.

1) I've often read that ideally the depth of the room should be greater than the width. And when you ignore the closet (opposite Wall B), the B setup seems like the right way to go. However, that closet, which covers more than 50% of the rear, reduces the depth to 134". Maybe a 10" difference (144" vs. 134") isn't that big of a deal and there are benefits of having a decent portion of the room that extends back another 18" than what I would get continuing to use Wall A.

2) I was wondering about the off-centered windows on Wall B and how it might relate to SBIR. That is, I'm pretty sure at least one window will be on-axis with one of the monitors, but that's not necessarily the case for both monitors (i.e. one might be centered on axis while the other could be half on dry wall, half on the window - I'm probably not visualizing the path of low frequency sound waves correctly). Should I be concerned with the difference between the reflective properties of a typical US house window and dry wall? They're both hard surfaces, so I'm hoping this won't be problem.

Any thoughts on these issues?
