Ceiling diffusion

Most likely the first reflection point but experiment.

Diffusion directly overhead works the best to get the most impact from the panels.

You can try diffusion or absorption at the first reflection points. I have diffusion at the first reflection points on my ceiling, but I want to try absorption to see how it sounds. I also have diffusion directly overhead.

Let me know what you find. It's going to be some time before I experiment.

Hi how do you determine the 1st point of reflection on the ceiling? Any ideas that I can use? Thanks.

Thanks for the responses. I will start with first reflection points and experiment from there.

When facing my speakers from my listening chair my ceiling slants up from right to left from 7.8ft to a little over 10 feet. Should the diffusion/absorbtion panels be mounted flush on the ceiling or hung so they are parallel to the floor?
