great, didnt expect that much improvement
i followed Glenns (GIK) advise from this thread https://www.gearslutz.com/board/studi...-absorber.html
and just by walking around in the room i was floored by the fact how important rear-wall-trapping is :D
i did some sweeps yesterday and noticed 2 nasty 20dB nulls in the 70-100Hz area..
i have no ceiling cloud yet, so i dont know if posting measurements makes sense at this stage..

ill keep you posted with my actual layout and placement of traps n panels

I would not be surprised if you are not getting something from the ceiling and or side walls. Looks great though for the back wall!! Nice job!

Nice idea.

Are you pushing it all the way up against the wall?

its about 1-2" away from the wall, just what the floors sidebars and some cables need; but i can imagine its even more effective with a bigger airgap

Yes spacing it off the wall can only help.

I'm trying a similar thing with this same train of thought...

I've been trapped in a tiny bedroom for over a year and i'm finally moving into a place where i have more space to stretch. It's an odd-shaped room and I'm guessing the half circle wall works in my favour? Anyways, i'm open to any suggestions you might have and im happy to totally rework the whole thing if required.

I don't have a floor plan with exact dimensions and i can't measure until we are there in two weeks, but i have included estimations .. trying to make do with whatever i have to work with in preperation.

Here's the diagram:

The Ikea cabinet is similar to a picture i found on this forum, with this as the main difference:

View image: individual

I have some bass traps for the corners at the bottom of the diagram already and i have 16 tiles for the vocal booth area.

I'm looking to buy something for the first reflection points at the moment, but im not sure what the do about the fireplace.. maybe a gobo in front or something?

Hate to be the bearer of bad news but the half circle is not helping you. It will tend to focus reflections, and will almost certainly cause some sonic problems.

Most likely the best way to treat it is to put as many traps in the half-circle as possible, or use freestanding traps in front of the circle.

Better to know that to not!

I guess I could consider reversing the room design..or will that make no difference?

The back ported yamahas will then fire towards the rounded wall in that scenario (rather than the vocal booth) ... I was hoping that the ikea basstrap would absorb some of the energy before it hit that wall in the previous design..
