Do you have the 150Hz firmware and is that what you've dialed the 600 to?
How would I check which firmware I have?
Also, Jakeman, sroode, and others, thanks for the detailed responses. I'll use the 30 days to experiment more and see how much improvement I can work out. I've also downloaded the REW software and will give it a run as well.

I'm very interested to see the results of the scan.
As a side note, when you calibrated your sub, what setting did you wind up leaving it set at? Flat, Half, or Full?
