Thanks Bruce...
What I was trying to do was get a full response of the sub(s) without any crossovers first. They are suppose to go up to 200hz via a ground plane measurement posted (they are Mark Seaton Submersives). So, to bypass all of the crossover settings in the preprocessor, I plugged the soundcards output into the analog sub input on the back of the processor (that we would use for sacd and dvd-a playback). It really wasn't that I was trying to do anything fancy. I was only hoping for a full frequency response of the sub through it's posted range.
What I thought might be killing it's response, given the way I hooked it up, was if the pink noise generated started tailing off like the target line on the plot above. If it doesn't...then I don't know why my subs response is so horrible when it gets out past 100hz. Here is a plot of what I'm talking about....please disregard the red line. The green line is the response of both subs from REW before I did anything with eq.
