HPF LPF Settings

Looking for help with a starting point to set the filters (LPF HPF) on my preamp. 

Olympica III speakers, 35 - 30k 

Sub 2 Sunfire HRS 10, 20 - 100Hz

NAD M12 

I know there are a lot of variables. Just an opinion where to start, I have never set HPF, LPF.


Usually the subwoofer crossover is around 60 to 120 Hz,  In your case, I would consider something around 80 to 100 Hz and see what sounds best.   Trust your ears, you can always fiddle with it later after you set it.
