After reading a little bit more about Multi EQ XT, I realize that its only really good in loud situations where it has to equalize in an odd-shaped room. Some posts on their forums suggest that the Dynamic EQ is more practical in its noise level.

I don't know how much noise it would all make anyways. It would be facing away from the wall that they were behind, but I'm wondering if we should soundproof the walls with something. hah

Also still having trouble with the placement of my receiver. I can't really put it on the wall with the screen, and I really like people's setups where it is neatly stacked on a shelf in a cabinet or on a rack of the PERFECT height. I could always put a rack along the left wall maybe?

Had a suggestion for these

Any other reasonable storage options for A/V devices?
