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.

newbee,

Those are the Vortex Acoustics (Von Schweikert) VR-35 speakers. They are designed to be close to the wall, kinda like the old Snells.

I have a virtual system and uploaded 2 photos there.

I have tried taking the outermost 2 panels down from behind the speakers. Yes, those panels do "pull" the sound towards them.
The 2 Music note panels (from ATS) are purely absorbers. Have not pulled those off yet because A. I like them B they use Z clips rather than small nails to hold them up. Might leave a nasty scar. I’ll try it anyway.
The ceiling is "acoustical" tile but I don’t know how absorbent it is.

That being said, I’m a little wary of putting something on the ceiling if it’s going to pull sound towards it. Maybe some white Sonex JR panels just for an experiment?

Wow, thanks for all the responses.

A couple things: The GIK Impression panels are marketed as absorption & diffusion which the wooden decorative plates are supposed to be providing the diffusion.

baylinor There ARE bass traps in the corners behind the speakers.

I’ve had these speakers for a long time (and have been considering a change). They have been in 3 rooms and every time I’ve pulled them away from the back wall they loose bass, but I’ll give it another try in this room.

ronboco I did build this room myself. I consulted the people at GIK and went with their advice, and they wanted me to buy more so yeah, they are trying to sell treatments. I’ll look at hdacoustics.

One of the things I should have made more clear in this thread was that these speakers were designed to be close to the wall and not toed in, unlike most others.

From the manual: "We have found that placing the speakers from 3” (75mm) up to 20” (500mm) from the wall results in the best bass power and tightness. Please experiment but make sure that the speakers have had at least 500 hours on them before making your final decision".

I have tried moving them away only to loose bass. The bass response is great right now and I have taken the diffraction wood panels off the front of some of the treatments which has helped. These speakers worked great when I had to share the living room and was not able to have a pair that needed to be pulled far from the walls to sound the best. 
I think that since i have a dedicated room now, that It may just be time for different speakers.
