Dimensions are 24"x24"x33" at 6' tall. I don't know why my puppy wanted to be in these photos so badly. I used Roxul RHT40 4" 4.0 pcf rockwool insulation. Itchy stuff. I bought about 4 times the rockwool I needed for these two traps due to an embarrassingly poor material estimation; so I'm going to make another two traps like this and about a half dozen panels. Overkill? Absolutely. Fun? Not at all. Estimated price for 4 of these traps and 6-8 2'x4'x4" framed panels; ~$500, including tools.

Sep 06, 2011 04:49 pm I really have no idea...but I'm building two more of these plus 4" thick panels to cover early reflection points. I didn't do any of the room testing acoustic measurements, so I'm guessing. I've since read some stuff about the possibility of "over-treating" a room. Maybe I'll have that issue to work through later...
The plan is to put these two traps up with the long sides behind my monitors, facing in toward mix position. I'm figuring that since most acoustic problems should be low end, and since low end projects in the shape of a sphere more than high end, putting big traps behind the speakers will cut down on low end early reflections better than anything else. I dunno...sure as heck going to keep these things for as long as I can. What a PITA to build!

Sep 06, 2011 04:52 pm hahaha, well, decent bass traps, without the latest in expensive treatment and technology, is pretty big, so yeah, I can see the size, just caught me off guard seeing them :-)
If they work, I'd love to post an DIY article about your experience!

Sep 07, 2011 01:37 am haha, after failing miserably to achieve symmetry with my arsenal of newly acquired power tools...I am forced to assume the same, lol
Sep 07, 2011 03:56 am Haha, nice. If/when we finally move into a bigger place where I can really start to treat a room somewhat: Well, my father in-law does woodworking as a hobby, so I'd try to get him to build me some good frames for the traps, and possibly some other stuff for acoustic paneling. He can probably also bevel them so they fit nice and flush with the corners.
If I get diffusers, I think I'll just have to buy them somewhere, since they're built to more scientific specs I think.
I'd love to have a nice big room though, something like 13' x 17' I'm fond of the idea of having a room with prime numbers for lengths and widths. xD Though often the LxW both seem to be divisible by either 2 or 3 :P I think I remembered reading somewhere that having the length and width of a room being divisible by the same number is not so great acoustically? This is assuming a typical rectangular room.
(though I'd be curious as to how something like a pentagonal room with a domed or vaulted ceiling would sound)
Ash well, not trying to hijack or derail the thread. I was thinking out loud there. :)
As for power tools, I'm handy with a power drill, and a dremel, and that's about it. I've never used a powered skill saw/circular saw or router or anything like that. :P
Sep 07, 2011 10:09 am You might have him make the corner trap frames from wood, but my understanding is that the most common DIY designs for the panels may limit their absorption qualities by quite a bit. Apparently having the sides of the panels open as well as the face of them is a big deal. Just what I read, not what I know as fact. I'm using drywall beading and pop rivets for the panel frames.
Placed the traps last night and left 3 bags of insulation in the room while doing a listening test on a bass heavy song. What a difference!!!!
