Wood Diffuser help

**MichaelsMinute** · April 14, 2023, 05:55 PM

I'd like to adde a wood diffuser between my speakers. The spot I'd like to put it in is perfect for up to approx. 24" square diffuser.

There are so many shape, kinds and brands of wood diffusers I'm no sure which to consider that are ACTUALLY effective.

I use GIK for my absorption and like their products, however I'm not sure how their diffusion is where they are relatively flat panels for that size vs. something more effective.

Suggestions and advice is welcomed!

Thanks guys.

you got to understand that diffusion will only work in a bigger context.

one thing is that propper diffusion would need deep panels that go down to 200 hz. those costs a lot and you would need A LOT of them. forget the little space between your speakers, a big part of the frontwall would need to be covered and the BACKWALL needs to be very covered. makes your room smaller. and costs a LOT. then, there is a physically defined distance from the wall to seating position. you need a pro to calculate it.
another thing, room treatment is also room, speaker and preference/music dependent.
there is a time difference between direct sound and reflected sound and diffusors might alter that to your dislike (or improve it to your liking).

a million people have bought diffusors but only a handful got true diffusion.if you want good acoustic, your fundament is bass absorbtion. you focus from 60hz to 200hz. it is safe as you cant really overabsorb.
then, if you want more, you got to think deeply about a concept for the entirety. whatever you choose, it has to be broadband. means if you choose absorbtion panels, they should be 20 cm think to go down to 200hz, otherwise they just create imbalance.

as for frontwall, there is no clear science. modern approaches go towards curved and wavy designs. diffusors are a bit outdated and some acosticians try to just scatter the sound behind the seating position on ceiling, sidewall and backwall towards the corners.

many including me, do belive that currently the best panels, respectively the best rooms worldwide are done by smt from sweden.

rather than a panel between speakers, my recommondation would be to buy 3 of the acrilic wings and place them right behind your chair / sofa, maybe half a meter. 10 times the effect and save to be on the good side.
you can add more wings on the first refletion points at the sidewall and later also on the frontwall.

this room for example is all around treated with smt wings and then covered with fabric.

Thank you.

I do currently have bass traps that are working well. I'm going to check out what you linked to. Thanks again.

Vicoustic makes some nice wood diffusers in various finishes. I use them at a few locations in my room along with various other treatments. Mike uses some of these at the Suncoast store. They’re available in a 24” size.

I'll check them out. Thank you. From a brief look it looks in line with what I was thinking in my head.
