Hi, there I'm about to move into a new space for mixing and recording and I need some help with a few problems and some tips on where to start. I just want to get a starting point as of now. I'm an amateur and use headphones a lot, so I don't expect perfection from my room or budget.
2. This side has a sliding door that I need to be able to open. It's okay if I can just reach in behind a bass trap and get to the handle.
3. There is a stone bench over the radiator in the corner that I can't move, which means it very hard to get symmetric absorption.
I'm not sure where I should place my mixing desk. Would it be best to face the problematic end of the room or have my back to it? I'd personally prefer facing the windows, because it looks nice and I wouldn't get any screen glare that way.
In terms of absorbers I'll start by putting panels in the corners - floor to ceiling. Do the mirror trick with the sides and add a cloud over my head. What should I do with the wall in front and back of me? Where do I need diffusers and what kind would be cheapest?
Face the glass door/window. In theory, your listening position will be 38% or 203 cm from the front wall (glass door) but you can fine tune this with listening tests and acoustic measurements.
Do the best you can but don't obsess over symmetry on the front wall as the speakers are firing away from it.
Go back and re-read all of Ethan's stickies and links. The position of the cloud, depending on it's size might not be exactly over your listening position. It should be centered on a point between the speakers and your listening position...just like your RFZ panels on the sides. If you want to make it larger, that's ok but it's primary job is to absorb reflections from the speakers off the ceiling to your listening position. In larger rooms, it would not be wrong to have two (or more) cloud panels. Panels can be built with sides that are not solid wood or metal but with holes or slots to allow the sides to also absorb. If you do this, spacing more panels about an inch or 2 can increase their effectiveness somewhat. BTW, I think 4" thick panels spaced 4" away from the walls or ceiling is a practical, effective design, you can go thicker but 2" is the minimum I would go.
