Changed Speaker Placement NOW BOOMY

I will upload new pix of the room now that I see what i have posted it is changed a lot it may shed some light on the problem if you all saw new pix.

I will upload tonight and also try the pillow experiment.

Timlub- are you talking about corner traps? For the walls I have thin wood (pegboard like) 2'x4' boards and 2'x4'x2" high density fiberglass panels to glue on and wrap in fabric. I'm placing 8 panels on one wall and 4 panels on another (planning to buy another 6 - 18 total).

When I bought panels salesman showed me the room with walls made of similar material and effect was incredible. I could hear his voice so pure and coming directly from his mouth. I know that acoustically dead room is bad for music but I'm very, very far from that. I have a lot of reverberation in 15'x25' room that has cathedral ceiling starting at 12' (a lot of walls). Thinner materials like fabrics or blankets don't do any good. If you place such material if front of you and can still hear thru it the it is no good (won't stop wall reflection)

Yes, these would be for corner traps, in an earlier post, you commented, "but I still need to take care of the corners" and yes, thin materials are useless. Are you hearing reflections from your vaulted area? Years ago, I ran Marcof Electronics/SpeakerCraft out of St. Louis, we had a dedicated listening room, the best it ever sounded was when we wrapped standard R13 fiberglass in speaker cloth (very nicely done), we did a live end/dead end room. The fiberglas was covered in brown cloth and black cloth and hung in rows, alternating the colors. Very nice room. If I tried that at home, I'd be asking Golden Ear to make room for me next to him on his porch.

Timlub u me and most of this community I suppose lol. I really appreciate everyone trying to help. I will take some of the thoughts and act on them tonight and report back with new pix.
