Thank you for your help Bruce,

I currently run my X-Over at 50 so I did a graph with this X-Over and another at the 80Hz X-Over.
My mains go down to 30-35hz so I set my crossover about double this at 50hz.

This 1st JPG graph is with the 50hz X- Over
The 2nd JPG graph is with the 80Hz X-Over

Do you have any thoughts on what you are seeing with these?
I start out well out of the gate with good readings at the first octaves but at the 22 there is a significant drop. Will the equalizer in my Pioneer VSX-92 be able to lift up this drop?

I am going to purchase the USB Sound Card so I can go deeper into this but I thought this would be a great place to start to learn about calibrations.

Thanks for your help and thoughts.
