Recording architecture diffusers..
« on: June 16, 2009, 02:27:00 AM »

All the studios designed by  recording architecture (aaa-design.com) seem to have similar diffusers... Large pieces of wood with holes cut out of them.   Are these effective?  

They don't seem like they'd be hard to make a bunch of for a tracking room.

Had a quick look, they don't look like diffusors to me...

Though RPG did design this:

Never tried those, but maybe someone on the forum has? Francis?

RA has a division that sells acoustic products (http://www.blackbox-design.com/) where they market those panels as actual diffusers.  

Seems like they've designed a lot of high end studios and they would know what they're talking about, but those panels don't look like they could be that effective.

Yes, serious company.

Still, hard to say...

Anyone?

Yeah I've used the Binary diffusor panels (BAD Panels) from RPG plenty of times. They are basically absorber panels with a little bit of mid-high freq scattering... If you want something back from an absorptive surface they work nicely.

The RA Stuff.... I really don't see how these are diffusors.... Ports to Bass traps... I could see that... but diffusors???

Thomas,

We use the RPG BAD panels all the time. They have excellent low frequency absorption, as well as mid/ high end diffusion. If you talk into one, and compare to an apsorptive panel, the difference is pretty profound. They leave a lot of high end intact, and that really helps when it's so easy to over-deaden a room.

Thanks Wes.

As in all the designs I do all the panels and systems are custom designed and built, I never work with RPG (or any other "brand" for that matter). When the opportunity/conditions arise, I will for sure try those BAD panels.

And you've done some very nice looking work. Kudos for designing all of your custom diffusors yourself.

As for RPG, they are really different from others brands, in my opinion. They do have a wide variety of off the shelf products, but they are also in to doing custom designs for specific projects, or altering existing designs for a unique application. By working with them we tap into a vast knowledge base and some of the brightest minds in the business.

Plus, RPG has recently aquired a really cool 3D printer, that can print objects! So, if you come up with a diffusor shape that you want to test, they can print that sucker out (in miniature of course), and take it to the lab for testing. And they do have a nice test facility as well.

Do BAD panels stop flutter when mounted parallel to another wall or do they need to be mounted at an angle?

Yes, BAD panels are very effective in treating flutter echos.

Bob Hodas created reflection free zones with BAD panels at Paul Stubblebein Mastering in San Francisco.

A great result.

BAD Panel was develloped by Jamnes Angus, who is part of the staff at Salford Uni.

I have used and sold thes BAD panels and they work but are much more than the pictures on the first site who appear only to be perforated panels.

Andre,

I've used as well quite a bit... but they are perforated panels in front of Fiberglass (at least from RPG)... what 'more' are the devices you have used?? Mind you, the perforation is a binary array.. thus the name, but it is a 'perforated panel'... please elaborate.. thanks.

I did not explain myself correctly.

What I meant was that the BAD panels are much more than just ordinary perforated panels as shown in the pictures on the first post.

I have used RPG ABSORSOR, BAD PANEL, MODEX, QRDs and the lower PROFOAM and PROCORNER for small home studios.
