Please help my odd shaped control room

coffeedrinker · 16th February 2009, 08:05 PM

Hi,
I need help ! I have just been moved into this room. Trying to make it work as a control room but the low end seems out of wack.
I'm using Mackie HR824s at their normal settings & I'm facing the window about 57" away, with the door off to my left side. Am I sitting in the best listening position?
I also have drapes covering the window to make it less reflective. The ceiling is 8' high drywall with insulation (safe & sound?). The walls are also drywall with insulation (safe & sound?).
In Hand, I have 6 GIK244s (front corners & top & bottom), 6 afeo Panels(aygo broadband? traps), across the corners at the back. Also there are Primacoustic foam panels at the side walls between the speakers and the listening position. Do I need any diffusion? Am I trapping the bass correctly?
Appreciate any advice.
Thanks!
Dave

You need to trap the back wall and probably add broad band treatment to the ceiling above the mix position as well.

You said you were floor to ceiling in 244's in the front corners, right? And you have the other two where...at the wall/ceiling corner in the front of the room? I'm a little confused on that.

GIK244s - one on top of another on the corners (3 right angles - left, right and rear right), one afeo panel mounted in the middle above the window, one below. Remaning panels on the walls behind and on the slanted wall rear left. all mounted 2" away from wall.

Do you think facing the window is the optimum listening position?
I'm thinking of removing the drywall from the ceiling and just filling with roxul safe&sound (I have a lot left over). Will this help?

I've used tones to graph it out.
There's a big dip from 40hz down, +8db around 50hz, dip on 110hz and mostly +6db and above for 130hz upward.

Thanks for the reply.
What else can I do?

I would orientate myself so the window is on my left.

Making the entire ceiling a cloud is not a bad idea, but only after all corners are trapped.

I tried to position myself with the window to my left, but the door directly behind me feels uncomfortable.
Also I started ripping out the ceiling along the rear, man, tough work, and extremely dusty. I stopped after an 8" wide strip 8' long. will mount 2"x4" afeo traps across the corners and try to stuff with SafeNsound behind the traps. Will this improve the bass trap efficiency?
Also made 2 frames, 2'x4' and will pack with safeNsound, and mount directly above listening position between speakers and me.
Hope this works.
Will report on results soon.......
Thank you all.....
More advice please..........
