I appreciate the feedback, guys. Mid-wall on the sides is actually very convenient. The side walls are where I have space to play with. I don't think I can actually fit one on the front or rear wall.

I'll have to see about REW. I don't have a laptop, but my computer is in the next room. Would it be possible to use it that way, going back and forth between rooms?

I'm not sure how much effort I want to go to in my current room, but it would be nice to get my feet wet for when I do move my system.
