Congratulations ! You are about to address the most important component of your system : the listening room. Every room has at least 3 resonant modes : length; Width, & Height. The worst ofenders for generating standing waves are the interfaces of wall/ceiling, and Wall/wall/ceiling i.e. corners, the latter being the worst and actualling having a "horn amplifying" effect. I have found that the front and rear wall/ceiling interfaces are worse than the side wall/ceiling interfaces. These can be effectively tamed using convoluted urethane foam such as mattress pads. This is a cut-and-try project and the process can be somewhat lengthy but well worth the time and effort. Start by cutting strips about 4" wide and mounting them in a wedge design at the critical interfaces, securing them in place with push pins. After mounting them listen carefully to the results and then shorten or lengthen the pads & listen to the results. When you are satisfied with the results get some cast off appliance cartons from an appliance store and cut the pad backings from them and mount the foam on them using liquid nails. Then consult the spouse as to her favorite colors and buy some double knit fabric (very sonically transparent so it won't change the damping characteristics) and cover the pads. Re-mount the pads using thin wire nails and relax and enjoy ! To address the 3 natural resonant modes of the room check a post of mine last month dealing with using Jon Risch's Room Tunes and how to calculate the modes of the room and tune the the Room Lenses to those frequencys.Happy Listening !
