Final Stages of Control Room Treatment

[studiogenocide]

We are finishing up our studio and wondering if I am heading in the right direction. We have a lot of 2 x 4 lumber left over from construction and a lot of fiberglass insulation. We need some absorbers placed throughout. We are about to cut the 2 x 4 to make frames and pack with insulation and tightly wrap with cloth ranging from 24" x 16" on up to use as absorbers all around my control room, which is almost a square in shape (16' x 18') I want to make sure this method is conventional and practical before I spend my time doing it. I appreciate this last minute advice from you all, and I will post pics soon.

I'd say that all depends on what type of fiberglass insulation you have...

We have rolls of the 3 1/2" stuff as well as the 9" stuff- all faced owens corning. We have about 3 40 gallon sacks slam full of the stuff, more than enough to do what I am thinking of doing. Look forward to some feedback!

You need corner bass traps. The usual material is rigid fiberglass, not fluffy batts, but batts can work if you compress the fiberglass to be about 1/3 the thickness. Much more advice here:

Some pics: pre panels

Here are some pics of the room pre panel. It really stinks it is almost a perfect square- thank God I have plenty of resources to make the panels!!!

Yep. Keep going with the bass trapping. With few exceptions, the more the better.

Alright... I put up 5 panels 4" thick on the wall directly behind the mixing desk, and it stopped much of the bouncing- I am just amazed at how well this worked. I will be putting up more on the other walls, but all I could get out of my lumber and insulation at this point was about 7 panels.

what did you make your panels out of? Can we see some pics?

Thanks!

lol, a new believer! Spread the good word.

Its True! Its True!!!

Thanks Jeff- again, I am just amazed at how well this really worked... To answer your question SJ, for the bass traps I used rigid fiberglass 9 1/2" thick and packed 7" (2 x 3 1/2") underneath it so it is really compressed. I used 2 2 x 4s at the end of each trap (parallel) to hold them in place to staple, and cut 2 x 4s and placed them horizontally and cut to fit flush so I could staple the fabric over them. I finsished the stapled edges with leftover carpet remnants.

For the 2" panels, I used the 3 1/2" rigid FG and cut the 2 x 4 down the center to make 2 x 2 frames approx 24" in height and 20" width. I stapled cloth over them really tight, installed a picture mount hardware on each of them and hung in place. It was my own method, but it worked. My idea is to hang at least 1 0panels in the booth, and about 15 4" deep panels in the control room because it is so square frequencies just bounce all over like crazy. I hung the 4" deep panels (same dimensions 20" wide and 24 " height) on the wall in front of the nearfields and it DRAMATICALLY cut down on the bouncing. I can only imagine what more panels will do for this room!!!

I will try to post more pics, but unfortunately I did not pic of them during construction... sorry Sorry about the lac of pics, my file sizes are too large, I will post some more links on my mysoace account if you wish to go see them there: www.myspace.com/michaeldaltoncountry
