There seems to be some solid advice so far but as you can see it has been trial and error for the other members mostly. Gik seems ok but in the end they need to sell products. It looks like you built your room yourself. I built mine as well. That is alot of work and you want your room to perform at its best. I HIGHLY recommend consulting an acoustician to evaluate your room and go from there. This is what they do. Jeff at hdacoustics is very good and very reasonable price wise. He was recommended to me by the highly respected member Duke LeJeune and I am very happy with my decision to have him design my room. There is no need to spend possibly years trying to get your room right. Good luck
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.
