Need help from you acoustical experts

Here is the latest version of my new listening room. Everything is nice and symmetrical. Depth is ok, width could be a little better. Most of the treatments are from GIK Acoustics, placed where they recommended.(mostly).

Treatments on the side walls are at 1st and 2nd reflection points.

Walls are drywall screwed and glued to steel studs, paneling glued and strapped to drywall and filled with Rockwool. The ceiling has R30 insulation covered by CelingMax grid, screwed to the joists (not hanging). Dedicated circuit for the stereo, and HVAC ducts insulated to keep it quiet.

Yeah, it’s very quiet. Creepy quiet.

My issue is probably with the treatments. Midrange/singers are very forward, and high in the room. Usually as high as the white music note panels, and sometimes the singer sounds like she’s on the ceiling between the speakers.

Anyone see a mistake I’m making with the acousticsounds panels, either placement or type?

I’d like to post some pictures, not seeing how to do it. Guess you'll need to look at my profile.

OP:

Diffusors pull towards them. Pure absorbers do not and that’s the only thing I’d recommend. I believe some one makes a broad frequency absorber that will drop in where you have ceiling tiles. As I recall, those "acoustical" tiles are very reflective at higher frequencies. If you can find the drop in panels with a wider range you’ll be all set.

Your problem isn’t the absorbers, it’s that you have combination panels with 3d diffusion in a tiny room.

As a quick test, throw some towels on the tallest combi panels.

BTW, I am not recommending you get rid of all your diffusors, just change the mix that is above the height of your speakers to be more aborbent.

I just looked at your system here on A’gon. If that’s the system you have problems with, the issue is the height of your diffusion panels + the low ceiling.

If your ceiling was higher and had broad-band treatment it probably would be OK.

Remove any diffusors next to/behind your speakers that are ABOVE the level of the speaker. Ideally those should get replaced with simple absorbers.

While I generally applaud the use of a mix of diffusor/absorbers, I think you may have a little too much diffusion going on. Diffusors tend to pull the image towards them, so everything above the speaker level is going to encourage us to hear taller images, while diffusion to the sides encourages the sense of a soundstage wider than the speakers.

Also, a couple of pure abosrbers in the ceiling between the chair and speakers would probably go a long way.

Sounds like a strong ceiling reflection?

What kind of a ceiling and what is on your floor?

Do you have more than just 1st and 2nd reflection point panels?

Oh, and what speakers are you using??
