Inexpensive acoustic treatment.

Jess, do u have google hangouts and a web cam? If u want, we can connect online later this eve, or tmrrw and I'll show u a bunch of really good stuff I did on the cheap with great function and pro looking results.

And get some 1"x2" boards (sometimes called tomato stakes) and build a frame to stretch your burlap over.

Like this (this is a corner trap for bass):





How it looks on the wall: 



But you can make the frame any size/shape you need.

Also, I have panels made from rockboard 60 (slightly lighter and more extended high absorption) and all I did was buy a roll of on-sale burlap from an online fabric store (I think it was more like 2-3$ a yard in quantity).

ATS also sells 3$ clearance burlap too, which is better quality overall.. www.atsacoustics.com/lightweight-burlap-fabric.html

Overall I think the panels should be RB60 and 3$ burlap, which with shipping and tax comes in right around 18-20$ per panel. Spray glue can be bought at Lowes or HD for cheaper than at ATS.

Not bad.

I bought burlap (or you can use cheap porch screen) from the local fabric store for super cheap (it's poor quality but works on the backs of these things).

The rockwool isn't completely limp like fiberglass batts, but it's not going to support any weight.

I feel that trapping corners is mandatory, especially in the room where you mic things up.


You can see all my corners trapped:

Softer works better with depth, rigid works better with shallow applications, it's all about gassing properties.

svarts stuff is cool!

u also cannot over trap, especially in a smallish room.

I used this guide when I made mine (I'm no expert, but I think it's good to have an air gap behind the panel, which this design includes).

I wasn't happy with the smushed edges that I ended up with on the first one that I made, so I bought some drywall corner bead to make a front frame that just rests in place, and is secured by the fabric. The corner bead is riveted together (very cheap and easy to do). This gave the panels a nice professional look and matched my GIK panels perfectly.

All of the panels in the drum cloud pic were made this way. By the way, I used Knauf Ecose from atsacoustics. I bought fabric on the cheap from Joann's or Hancocks, I can't remember. They always have coupons readily available for pretty big discounts.

I can provide more details on the corner bead construction if you're interested.

2" Corning with feet mounted on the back corners which give 1/2" of clearance from the wall. 

Hey Jessie if you can find a local A/C supply store they sell what is basically 703 FRK in 4'x10' boards for about $60. The acoustics are almost identical and it's wayyyy cheaper. Also, if you buy a box of it they'll cut you a deal. I paid like $150 for a box of 4 boards. Certainteed makes a version and owens corning makes a version, but the coefficients are very close to 703, in fact, it's so cheap you can double them up and get better results and still be paying about half the price. If you don't like the foil you can just pull it off, but keeping it on improves the absorption across the whole spectrum. Just find an ac supply store, give them a call, and ask how much their 2" duct board is per sheet, then how much for a case.

If I grab these 12, 2" 703 panels from the guy on craigslist, would that be a bad move? Could I just double a couple of these pre made panels in spots to make them 4"? @$15 each and not having to do any work, they're pretty tempting.

Yea I'd offer a bit lower if it were me. Assuming you take the whole lot it's not like he's going to say no, he doesn't have anymore use for them and he'll take lower. You might even offer a lower price and he'd take it. 

cool!
