Most of the diffusers on ETSY are diffuser shaped toys. ETSY is not where you get diffusers from. They need to be properly engineered for a wide enough bandwidth.
Powered speakers show audiophiles are confused
17 of 23 speakers in my studio and home theater systems are internally powered. My studio system is all Genelec and sounds very accurate. I know the best new concert and studio speakers are internally powered there are great technical reasons to design a speaker and an amp synergistically, this concept is much more important to sound quality than the vibration systems we often buy. How can an audiophile justify a vibration system of any sort with this in mind.

Read the room dude. The OP, "I took 6 years of of math and physics in college all pertaining to electronics and sound ", and he does sound for major motion pictures. You keep acting like he is some sort of neophyte, and while this may not be his areas of expertise, pointing him to ETSY is both insulting, pointless, and of negative value. Diffusers, ones that work at least, are a major effort to build, and to work, they must have fairly substantial depth. http://www.mh-audio.nl/Acoustics/DiffusorCalculator.asp http://www.mh-audio.nl/Acoustics/diffusor.asp It is not about just throwing something up on a wall either. You have to consider what frequencies you are going to diffuse over, and being too wide, but not wide enough can make things worse, not better. https://www.subwoofer-builder.com/qrdude.htm There are some good absorber calculators out there too for the DIY: http://www.whealy.com/acoustics/PA_Calculator/index.html . You have to know the resistivity of the material. There are some papers out there where you can gleam that info: http://www.ica2016.org.ar/ica2016proceedings/ica2016/ICA2016-0490.pdf

I get the impression the OP is here for entertainment, he is baiting both of us and clearly has not taken much in the way of advice. You saw the pic I posted of the Titanic right? That is where this thread is going, good luck with bailing it out. Do you think someone who is going to have a movie mixed will use a guy, any guy, who built his studio on the advice of a chat room? No way, you build a studio with someone who has creds and then you market it (this world class studio was designed by ______.) The OP married a $15K amp with $35K speakers and didn’t like it. In the same thread that he proposed ACTIVE speakers for many good reasons he didn't use them and now he’s stuck. Tubes burning out, bass no good, and getting advice on how to spend $200K from this thread?? Might as well use Etsy, did you SEE the stuff? A lot of it is art impersonating as diffusors I know, but it pops. At least his wife will love it😍

If you like traditional, the brochure for the bamboo diffusors I use are posted in my virtual system, but these look much nicer IMO. I got Geofusors (PERFECT for immersive audio) backfilled with polyfill so they double as bass traps on the ceiling and they work mounted on the walls too: The GeoFusor imparts a more neutral spectral balance to the room while revealing a more three dimensional soundstage (width and depth). Also evident is improved separation and placement of sounds in the image of a recording from left to right and front to back. |
