Axiom Home Page Forums General Discussion Technical Questions So how do you 'sub crawl' two units?

I have ordered, but they won't get shipped for a bit yet, two EP500 units.

Right now I have a pretty cheep Polk 10" sub that I think has a frequency range of 35hz-100hz, but considering my LFR1100 can cleanly get much lower than that sub, I didn't see the point.

Now I have seen many video's both here and you-boob-tube that covered the sub crawl where you put your sub where your listening spot is then crawl around to find the best sounding spot, then move your sub there.

Great for a single sub, but how does one go about setting up two subwoofers?? As each is sending out it's own wave, you are going to get potentially now more peeks (where the two waves cross on a peek or valley) or nulls (where a peak crosses a valley). How is best to find the right spot for two of them?
