For your acoustic treatment, you will want to use this. Give them a phone or email and say that you want enough for 4 8'x2' bass traps at 4". See how much it is then post on here, and I'll tell you if it's reasonable.
No, I dont have real pics of the basement because its being worked on right now. It is in the process of being finished, because right now its just a stone basement. The framing was finished yesterday, so its probably going to be about a month until its finished. I'll make a model of it in paint...
Yup, that whole room is usable. Not sure of the demensions, but its a pretty big room, what do you mean install a curtain, could you show me a pic of what you mean with the "where you mix sould be centred in the room against a wall".
Cool. I think someone said that you can get 3 batts of rigid fiberglass for $60. You'd need 6, so that's $120 plus wood and cloth. BUT they said mineral wool is cheaper and it does basically the same job. So it might be $100 plus wood and cloth, but it will make a huge difference to your room and your recordings will be MUCH better mixed, and recorded.
