Acoustic treatment for bedroom mix position

[mattr]

Ok, so I've finally found a desk that I deemed big enough
Got one coming from Ikea which is 2.2m wide... hopefully big enough for a 4u rack on either side (to raise monitors up) and 2x 24" computer screens (or 3 in portrait) in the middle Well, it will be 3x 17" for now until I find some 24-inchers I like.

So my next dilemma is acoustic treatment. I hope that moving from my current mix position (in a corner) will make a big difference, but I'm looking to take another few steps forward after that. I'm not going to be able to afford it all at once, but I'd like to have some vision of how it will turn out.

I've done some quick sketchup drawings of the part of my bedroom including where I think I might put some treatment...





...if its not clear from my bad drawings, my current ideas stand like this:

• Floor-to-ceiling (or as tall as possible) absorption panels directly behind monitors
• Another tall panel to the right of the mix position?
• A panel low down to the left, stopping at the sloping wall
• Foam wedges/bass traps in the corners
• Possibly another panel (or some foam/diffusion panel) on the wall behind the desk

Behind where I will sit is the rest of my bedroom, which hopefully has enough stuff piled up in it to diffuse sound fairly acceptably. The rear wall is about 4m behind the desk.

Its an old house with some lath+plaster walls and a weak ceiling. Ufortunately I cannot hang or stick anything to the ceiling, so the idea of a cloud or panel above me is out. I'm also limited as to what I can do on the sloping wall as I'm not sure what kind of weight it can support - I may have to put some foam stuff on there.


So basically I need some clarification on what would make the best use of the space. My budget isn't huge, but it can be "flexible" if good solutions are available Its never going to be a great room so I don't want to spend any more than is needed to get it close to 'as good as it can be'.

I'm yet to chose some monitors, but they'll be the standard 6-8" nearfields. I'll have them on some mopads and hopefully they'll be raised up to a good height. They may have to go a bit wider and so the equilateral triangle thing may not be able to happen, but hopefully it should be better than what I have at the moment

Also if anyone has any specific recommendations for fiberglass or mineral-wool to use for panels (I'll probably end up making them myself to save some money), or any other materials I'll need for my plans, then I'm open for suggestions.

Thanks


EDIT: One more question I'm thinking of getting some canvas printed for the two big panels to personalize them a bit. Will the kind of canvas they print on be too reflective? I'd order it off the internet so I wouldn't be able to see it before it arrived. Also, if I bought them already stretched over a frame, would it be sufficient just to fill that frame with the mineral wool?

I think people here will need overall dimensions of the room.

There are some dimensions for the area on the images. Its 5m from the wall in front of the desk to the back wall, then there's another part (roughly 3.5m x 1.5m) making it into a bit of an L-shape. I haven't drawn out the rest of it on sketchup.

I can only really treat the stuff around the desk. I'm not hoping to accurately 'tune' the room (which would be fairly difficult due to its shape, and the fact it still has to remain my bedroom ). Just to control the reflections and acoustics behind the monitors is my main aim.

Phase 1 (deskus erectus) is complete
It doesn't look much at the moment, but it'll get better. New monitors, acoustic treatment - should get there eventually!
It has far more potential than my old corner, put it that way...

It's a good start.
Can you center desk between right and left walls more or is it already there?
From a low budget concept, I'd place 4 inch owens-corning 703 panels on entire wall behind audio and video monitors and then do same on side walls back about 4-6 feet.

Might want to do same above listening area as well.

In my small room I have shelving and some auralex to break things up on the rear wall as well.

My room is pretty quiet/dead generally speaking which is the normal recommended suggestion I read on the forums for small rooms.

However, my music is generally lively and can be heard for blocks
