On a related note, what are you (who have VP-180's) setting their crossover at?

I have liked the sound of my SVS sub with a 60hz M80 crossover setting. However, I also REALLY like the sound of the M80's with a 40hz crossover, even though I lose a little bit of subwoofer oomph. I have a pretty big room with cathedral ceilings. It's really a terrible room. So, for the VP-180, I'm guessing 40hz would sound pretty nice in concert with 40hz crossover for the M80's.
