Hi Francis, welcome & great to see your new forum.
I'm building a CR at the moment & would appreciate some input on the acoustics for an accurate listening environment. Basically, I've been given a room (which I've been soundproofing by building inner walls, insulating, etc) which is roughly 5m x 4m x 3.5m in dims.
My idea so far is to build some bass traps, Ethan Wyner style, on the ceiling & possibly on side walls. Maybe I'll build them at reflection points and cover them with absorbant material. I have thick curtains I can draw over the CR window when mixing. The floor is concrete, which I'm planning on putting a timber laminate flooring on.
I can't afford to do anything too elaborate, but would like to know if I'm heading in the right direction or not. Any tips or ideas?
Cheers,
Glenn
P.S. Hopefully the picture below works - my good mate Greg Simmons helping to put gyprock up.
