Control Room Side Walls

[LDQ]

Hello All,

My name is Luis I and I just registered today although I’ve been looking at many posts on this forum for a while. With that been said, I finally was able to find a house, which has a decent basement, and now I am in the process of designing and building my recording studio. There is a bunch of questions I have but I would go step by step.
One question I have is in regards to the Control Room Side Walls. I looked at the studio layouts examples on the SAE page as well as the studios under construction page plans and notice that all designs have the side walls of the control rooms at only one angle from the speakers to the back of the room. It is my understanding that ideally you don’t want any reflections from sidewalls to hit the sweet spot or mixing position. By looking at the plan and analyzing the angles there are going to be some reflections from the sidewalls that are going to hit the mixing position. Are these reflections neglected or are they all absorbed or am I missing something here. I’ve seen other designs in books where they use multiple angles on sidewalls in order to prevent this. Is this not done anymore? Does it have to be with only high frequencies being absorbed?

Anyone knows why???

Luis.

LDQ - it's based around the angle of directivity of the speakers. The high and mid speakers are directional, usually over an angle of 30 degrees.

I see what you mean...........What about the angle of the ceiling...considering that the height of my basement from floor to bottom of celing beam is 7.5 feet. Note: I don't have any HVAC ducts.

It's hard to break up angles with such a low ceiling - I'd tend to wipe it out with 703 and make it neutral.
