Bass Traps

Those will not work. There is a way to use them though. Get a sheet of 3/4" ply, stain it nice, cut it into four 12" x 8 foot lengths, one for each corner.Measure out from the corner about 18 inches an attach it angled back toward the other wall. attach the two foam traps to the inside in the middle. Then wad up some soft fleece blankets in the two 2 foot areas left. Other than that, use the right stuff and make your own. I set up bass traps in a friend's studio by wadding up leftover canvas drop clothes and stapling them to the back of four long triangle cut sound-stop and leaning them up in the corner. They worked fine and were really cheap.

Anyone have any opinions on these bass traps. You get 8 so I was thinking of 2 stacked up in each corner.

I know, eh? 9 out of 10 of his posts are complete useless nonsense (and I'm being generous with the 1, just in case he accidentally got something right, though I've never seen it). It's beyond being a joke.
 
I'm not sure how creating a new corner to treat would help in treating a corner...
 
I'm a complete noob at this stuff and even to me that advise sounds like you'd be building a reflector of sorts . . .am I wrong?

No, you're not wrong. Hard surface = reflecting surface.
 
Yes you are wrong, kind of. Norman is talking about trying to deal with very low frequency sound. Sound that will pass through the plywood. Some frequencies will be reflected by the plywood some won't. It's very complex.

Norman said take the plywood, strip it to 12" wide, set it up 18" from the corner then "angled back toward the other wall" - not sure what this means but there will be a gap on either side of the plywood - put the foam behind the plywood and stuff the rest with old blankets. Sorry, this is not good advice, even if the plywood will pass through the bass frequencies.

He's describing a corner trap.
 
Not good at all..there is no argument in favor of any of this as a membrane because he specifically said 3/4" plywood which on top of everything else is expensive. My old folded horn sub used 3/4" plywood. Even if you could use 3/4 as some kind of tuned helmholtz bass trap it is very pretentious to suggest it to someone without knowing what his room actually sounds like. The guy in front of me was right if we breakdown every little thing that is wrong with his post we'll be here forever..
 
Hi All,

I've pretty much been a lurker, but hope to participate more. The timing of this thread is good as I have been wanting to build some bass traps in my studio area. We moved about a year and a half ago, so I am starting over. (What am I saying? I never made that much progress at the other place...)

What would you all think about an approach like this? I guess, I'd call it "frameless."

Cut some 1/4" pegboard to 2' x 4' or whatever size you intend to use. Use spray adhesive to attach a piece of fabric to one side of the pegboard.

Lay the pegboard on the floor, fabric side down. Lay the Roxul, or pink, or whatever on top of the pegboard, and wrap the fabric entirely around the panel, stapling to the back. As a result, the entire front and all edges are available for absorption. The back allows for some absorption, due to the holes. If the holes aren't enough to absorb, remove more pegboard by using the pegholes as "corners" for the new larger hole. Suspend the panel from the ceiling, using pegboard holes to attach wire.

Kind if like the way seat cushions are made. Sorta.

Thanks (I think) for your reactions to this.
