Hi Everyone, I am in process of treating my new studio space and I need some help with it. The acoustic diffusers(Rectangle 23″x45.5″) GIKAcoustics is providing ranges from 70hz to 20k - the only reason I am not able to buy from them because the are literally on the other side of the world for me. I have been studying on how to DIY this thing but the only thing that I am worried on how to cover the frequency range? Check check out this perma link, the calculations I am trying to use with this calculator or with QRDude either. www.oliverprime.com/prd/?C=343&QSTEP=1&F_LOW=70&F_HI=20000&PR=5&COLS=13&ROWS=12&SHOW_INTERMEDIATE_RESULT=0&P=157

I don't know that calculator, but assuming it works you should aim for a diffusing range between 600-800 Hz up to 2.5-3.5 KHz. So that means wells about six inches deep that are 1-2 inches wide. Or just copy the dimensions of a commercial diffuser by a major vendor.

If you want to copy GIK's you'll probably need to get their help. The GIK does not look like a QRD diffusor and I don't understand how the GIK works; their website does not explain or show any detailed test results. If you go with a QRD, there are plenty of resources as opposed to the GIK, which for all I know, may not even work.

talha, you probably realize by now that diffusers are complex business. If you're really handy with a table saw then make a regular well-type diffuser. If not, just buy one. I recommend Real Traps', of course, but also because they're modeled after an industry-standard design based on verifiable research and both diffuse and absorb. Maybe those diffusers you've linked to create a true diffuse field but I've never seen any proof.

Diffusers are pretty pain in the ass, i didn't like making my QRD ones that much (they turned out pretty cool looking) I also made them pretty deep. I used QRDDude software to make these. I've made also "skyline" type diffusers, they were much easier to build. (didnt look that good tho) for these i used this website: www.mh-audio.nl/ACalculators.aspAlso all diffusers i've made, they ended up being pretty heavy.

I want diffusers. Don't have a table saw, though. Probably should finish making most of my surfaces absorbent first.

RealTraps' sending me their stuff to the other side of the world are going to be pain in the ass.
I am probably going for Auralex London 16 Kit but again they are not offering diffusers so probably going to DIY the diffusers.

If you're going to make diffusers, you might as well make absorption. I just found out that Ethan doesn't own Real Traps any more so just build that shit yourself.

LOL, I never use this forum to promote RealTraps. Well, not too much, anyway! But I'm still active with the company as an employee. So I still care. But I've said this many times: I'd rather see someone buy treatment from a competitor, or build their own, than go without. I've linked to the QRDude site many times myself.

You heard the man: go out and buy some genuine Real TrapsTM premium acoustic treatment. Accept no substitute!
