Found OC 703 in Milwaukee, WI... and some questions about trap design/placement

[wkomassa]

Hi guys,

After reading the first two sections of KHR, I immediately smashed myself in the face for my piss-poor control room treatment, and immediately resolved to have bass traps in place this weekend!

In the course of my investigations, I found a CHEAP supplier of OC 703 in Milwaukee, WI for anyone who is close by. It is Acoustech Supply - Welcome to Acoustech Supply Inc. | Supplier Of Acoustical Ceilings, Walls and Architectural Interior Finishes!

They had 1" unfaced 703 in stock, so I took a carton of 24 which should be perfect for 8 traps which will fit in my control room. The cost - $.43/square foot! The whole carton was like $82! I'm going to use 4" of thickness on my panels as of right now, but I was wondering if anyone had any suggestions on placement; corners vs walls/ceiling.

Here's the deal - I know my space is not ideal by any stretch. It is very small, well under the 2500 cubic foot rule at about 11' w x 8' l x 6.75' tall (basement, duh!) There are also some kick outs and door placements that make corner traps of any size quite difficult. I drew the attached floorplan to illustrate. (Sorry, it's crap, I'm at work and had to use Word!)

My main question, I guess, is whether it will be at all useful to put a couple 1-foot-by-whatever traps in the corners I can, probably 2 of them, or whether I should just put them on the backs of the two wood doors, behind the mix desk (IE behind the monitors), under the window, etc.? Or should I do the two corners and then the walls/doors as I can?

Other thoughts altogether? Oh - for the wall ones, I'd get them off the walls a few inches as well...

Thanks in advance!
Will

Massa, are those 2'x4' OC panels? If so, the first thing I'd do is go buy another box of the OC. That's a great freaking deal.

If it was my room I'd flip the desk so you were facing the window. This would give you the long end of the room behind you. The room is small enough you need to treat all of the surfaces. I'd start with 4" thick 2'x'4' Traps in all 4 corners and 2 on the back wall directly behind you.

Then 2" thick 2'x4' panels on the ceiling and left and right of you're direct listening area.

Like the previous post, sounds like a good idea to re-orient your room, trap corners and rear wall first. You could make a cloud also to suspend above the mix position. Not sure if im allowed to plug another site but johnlsayers.com was an excellent resource when setting up my studio. Also any info by Ethan Winer (search his site) is pretty solid,
