Search for rigid fiberglass in the studio building and display forum. This stuff is great too. You could make 4'x2' panels, like this, double thickness for bass traps, then use the rest elsewhere(first reflection points, side, ceiling and back wall, and in the vocal booth).
OC 702/3/5 is more expensive than most. The price $250-300 was based on brian's(bpape) 3.5" bulk acoustical cotton-$187, enough for 16 4'x2' panels. I took into acount the doubling up of cotton for bass traps, and that left enough for 8 4'x2'x3.5" panels. I'm in the UK so just guessed the price of fabric and wood over there (wouldn't expect it to be over $113 if bought in bulk, although i could be wrong).
I'm sorry, but firstly that is not auralex, secondly they call it soundproofing foam, and thirdly i don't trust the specs, especially the bass absorbers (1.25 at 125Hz).
With the acoustical cotton, shipping is included in the cost $187 for 3.5" bulk pack. It is made from recycled denim so, unlike regular insulation, is not itchy. It acts very much like 703.
Probably you... How much for shipping on your pyramid foam...
Only for the purpose of the ebay listing if I remember right. If you go to thier site I believe they are very careful to avoid that, but yes it made me laugh when I first saw it too.
You didn't misread. I was just commenting that it looks like it, but there's no way of knowing if it is similar to auralex. I'm sure the simple wedge foam works well, even the shitty egg crate foam i bought years ago works, to an extent. But for good quality absorption, i always recommend building your own with rigid fiberglass/mineral wool/acoustic cotton.I misread the original post. I thought he wanted something close to auralex but cheaper.
Yes they are idiots and call it soundproofing foam
I think I covered the fact that the bass traps are a joke.
The wedgie foam however does work well for helping to kill reflections and at the savings over auralex you could go with 4 inch foam if you wanted and I am quite shure get better performance than 2 inch auralex. You could also take the approach of being able to afford to cover more area.
I personally don't trust anyones spec's when it comes to this type of thing. They all are selling something and some how most comparison tests come out favoring the sponsor of the test. I have however used this foam to very good results for killing general sound reflection allthough my aplication of the foam is pretty unique and quite costly.
Anyway. Buyer beware on any and all things. Having used this product my self I will be damned if I will ever shell out auralex prices for simple wedge foam.
F.S.
It's reads like he wants discounted auralex.
