I need help figuring out how to best integrate my mains. Here is what I have so far:
Sub is an SVS PB12-Plus/2 with ports set at 20Hz
I also have a house curve set:
20Hz +5.0
80Hz 0.0
This is what it looked like before I started (sub only):
Here is the first crack with the BFD filters (obviously a big null around 105Hz):
Then I turned on the mains - I played around with the phase and this is about as good as it gets:
So then I decided to use the notch filter on my pre (B&K Ref50) to kill the hump at 80Hz, tweaked the BFD a bit more and ended up with this:
I have 3 questions:
1. I am using the Sub calibration signal to integrate my mains. Past 80Hz am I trying to hit the 75db line, or should it be dropping like the Sub target line? In other words, if you look at the hump around 94Hz, is it a hump relative to 75db or relative to the sub target line?
2. As its currently setup, as shown in the last graph, it looks reasonably good to me (haven't had time to listen to it yet). But when I go back and check my speaker levels, my Sub is about 10-11 db "hot" relative to the other speakers. If I knock down the gain on the sub, won't I kill this curve (lower frequencies will go down relative to higher frequencies in the mains). How do I get the speaker levels right?
3. Should I be worried about the big dips past 100Hz (or again, are they really dips)?
Thanks!
