Great point sssutherland, I was thinking of posting something along the same lines, but you articulated the point much better than I would have.
As loud as I've played my system I'm not too worried about the neighbors. We *do* live in a subdivision, but all the lots are at least one acre in size, so the nearest house is at least 150 feet away. In our old sub, the houses were literally like 8 feet apart. Distance is your friend in this regard. Of course, now that it's getting to be summer time and the windows are open, I'll have to be more careful. I knew winter was good for something!
