No I have 2 in the front and 2 stacked in the back.. Yes the last graph was increased by 5 db.. I recaptured the graph with better scaling..
Compression sweeps with better scale:
Here is how I set them up for those interested:
Here are the front 2 and their sum:
Here are the back 2 and their sum:
Here is the front 2 , the back 2 and all 4:
Notice that the sum of the front 2 and the back 2 is less than the back 2 alone after 50 hertz..
I added a LPF for the front subs to cancel their output above 50 hertz.
Here is the back subs and the front subs with the LPF and their sum:
Looks better than when the fronts were active above 50hz. It seems to me that I can use the output of the front subs between 70 and 80 to help get rid of the 10 db dip since there doesn't seem to be a cancellation there.
Before and after eq
I haven't taken pictures yet but planning to take some soon.
