Here's the sub graph:

I haven't messed around with the filter settings yet....I was pretty proud that I was able to even get the graph to work! "Baby steps....baby steps.."
I'll take a stab at them in the next few days though, I promise.
EDIT: BTW, placement of the sub is final. I can't move it....really....I can't. Check out my gallery, you'll see what I mean. The room is just awful, and the sub is quite big.
EDIT #2: Subwoofer to main speaker crossover was set at 80Hz
EDIT #3: I replaced the graph with one that tested the sub by itself. The dotted line represents my first foray into the Parametric EQ settings.
