The cut-out in the back is small enough that, when pushed up to the wall, the MWM will still support my K-Horn. Also, I measured the MWM (like I said, I have 4 in the garage) and it really does not stick out a whole lot further in the front than my K-Horn already is. Uglier, yes, but I thought most of this is about the sound and not how I can impress everyone with my Zebrawood cabinet. I just don't want to go to the trouble of setting all this up if it won't sound better. I am in Dallas if anyone wants these other two.
