I'm thinking of just mounting a thin wooden board with a lot of different sized holes in it on top of the absorbed panels and maybe screw in some leftover wooden pieces. Will this work or is the diffusion too random?

If you want "proper" diffusion, I would suggest a 1D QRD. www.mh-audio.nl/Acoustics/Diffusor2.aspCaveat: There are some online calculators out there that have errors. If you do choose to DIY a QRD, please verify your plans a correct. |

Here's is another site about QRD's. There's more detail including about the fins. www.subwoofer-builder.com/qrd.htmI don't think there's a particularly easy way to build a properly operating diffusor and small rooms won't necessarily benefit from them as much as they will from more absorption. |

Okay, my room is 525cm X 375cm, but the room is also my living room, so there is a lot of furniture and clutter around. So I'm only going for better and not perfect. I think building those panels from scratch is a bit above my level of ambition. I'd rather buy some premade diffusors, when I can afford them. Should I just hang the panels as is and forget about diffusion for now?

Your room is probably large enough for some diffusion especially if you're firing down the length, but sure, it's fine to just put up panels for now... and you just might be happy with that.

Hi tiggerdyret, I think you meant to post the below to this thread:
"Thanks, I'll look into diffusion for the next upgrade. So I guess my board with holes idea will only make things worse then?.."
I don't think the "Vicoustic" or your board with holes absorber/diffuser will make things worse, I just don't understand how they work and they may not offer "true" diffusion...but that's just a guess. I just think that from all that I can gather, QRD's or similar stepped designs are much more documented and tested than other designs so I would suggest you do your research focusing on them to see if that is what will improve your room acoustics.

Cool, I'll look into diffusors when I can afford a new upgrade.
