You sub's crossover should be the same as your mains.
The sub will still receive the signal from your surrounds below crossover 120 hz.
For example, if your mains' crossover is at 80 hz., your sub should also be at 80 hz. and have your cutoff at 120 hz for LFE.
This way the sub will receive signals from mains below 80 and from surrounds below 120 and will take care of the LFE up to 120 hz.
I hope it is clear.
My 4520 only has one setting AFAIK
... I have it set for LPF as 120hz.
