John Sayers' Recording Studio Design Forum Archive

For all of you who are interested here some pictures from my DIY Diffractal Diffusors which i built as long as im stuck with the ground layout of the studio...

I dont want to promote this idea as mine or sell it commercially because i think the company RGP Diffusors has the patent for this stuff...

I just calculated my own 1-dimensional QRD Diffractal for my needs

i think (i dont know and didnt measure it) they are diffusive from 500Hz to 16kHz

btw: these nice milled mdf boards with the N7 matrix in it are made by the carpenter and i paid around 250 € for 50 meters. this is enough for 6 diffusors...

not more to say... i dont have very detailed pictures because i wasn´t planning to do open a new thread about it but now i do...

i hope you guys like it and maybe its helpful... if u need some instructions for your DIY diffractal just ask

Andi

more pics to follow soon

here you go...


maybe its an inspiration for you guys

that.... looks... FANTASTIC! +1 for that carpenter too
thanx for sharing. Let us know when it's installed in your room, love to "see" it in action.

i´ll do that... when i find some time i could draw a sketchup model for this for those who wanna build their own... cuz its fun

of yourse mdf is not the most beautiful material in the world, but when its spot-lighted and mounted between fabric-covered walls it´ll be dope...

i got to build 2 more... i think that i document that more detailed from now on...


By the way: its a female carpenter

hurray for female carpenters

It looks like the MDF has a laminate on both sides. masonite?

no, maybe its because of the bad picture quality...

its plain mdf only





and maybe thats the woodglue

not that it matters, but this pic says otherwisse

oh you´re right... but i ordered plan mdf

never the less, it's still a masterpiece

yes it is... and its still a mystery how she could mill all these panels with a 1-bladed mill only and charge me only 250 euros...



that looks like it needs hours and hours

i think she miscalculated her work a bit

post her address, I'll be needing her services

she gotta be chuck norris´sister

Hi hansaffe,

Nice job on those diffractals. Can I ask: what is the width of those fins? Looks about 2-3mm by eye. I'm about to try and have some milled as an experiment but not sure how thin I can go without them breaking off with the torque.

Cheers,
Stewart
