Rotarius,
First of all, I'm using Magnepan 1.6QR's in my living room which is 16' x 20' x 8', carpeted, and has a fairly plush sofa and love seat. The speakers are located 4' out from the short wall and 34" from the side walls. I'm not at all sure the placement is optimized yet. I listen from the loveseat which is flush against the short wall opposite the Maggies. Anyone with suggestions?
I got two 2' x 4' Auralex studiofoam pyramid panels ($48 for the two), and glued those to a 2' x 8' Styrofoam insulation panel I bought at Lowe's. The Auralex glue cost $20 and the insulation panel was $10. I cut the panel in half to give me two 1 x 8 panels, and wedged them diagonally into the corners behind the Maggies floor to ceiling. I also bought some 1' x 1'auralex studiofoam wedges, sliced them into individual wedges, and attached those to the exposed ends to cover the blue insulation panel edges that are exposed. That was about $12 for those pieces. The nice thing about this arrangement is that they are just wedged into the corners, so they can be pulled out of place at a moments notice and stored in the basement or garage until the event is over. My wife hasn't complained so far. By the way, patience works well with finding a 2nd wife also! I've left the back walls untreated so far. Before installing those panels I was having some sort of horrendous reinforcement of certain notes from female alto, soprano, and French horns. I'm not sure if it was the fundamental or upper harmonics that was causing the problem, but it would run you out of the room with your ears bleeding. The panels really pretty well solved that problem. Im thinking about making similar panels for the 1st reflection points on the side walls. These foam panels glued to the Styrofoam are rigid enough to stand unsupported, so you can put a 2x8' panel together and move it around the room until you find the best locations. The nice thing about this is that you don't have to wait out a burn in period. You might want to check out the Auralex.com website. One of their dealers gave me a nice Auralex catalog. If you can find one of those, I'm sure you will get some other good ideas. You can also send them a schematic of your room and they will do an analysis for you. I'll try to e-mail you some pictures that may make the description a little clearer. I hope this works as well for you as it did for me.
