Thanks John. Great product, and I appreciate the help. I realized my graph was in the wrong scale right after I uploaded it

I will fix that next time I post.
I'm also struggling with another question. I've heard people on these forums talk about graphs showing issues with the crossover. I assume they must all be people with crossovers built into their sub? I have an SVS PB10, and my LFE management is all handled in my receiver. This means I'm pretty much out of luck as far as testing that component, correct?
I'm not really sure how its working right now - I suppose the speakers just kick in whenever they can and same with the sub. Does this pretty much invalidate all of my low frequency measurements? Any way around this?
Thanks,
Jeff
