Active line level crossover with subwoofer out - HELP

Hi.

Helping my friend with another challenge. 
Looking for a line level crossover. His preamp does not have a subwoofer out.

What he wants to do is have a high pass filter between the preamp and his power amp. This so his Spendor BC1’s are spared anything below 40 or 50hz. And, the crossover needs a low pass filter to spare the subwoofer the high frequencies. 
Thoughts? 
Thanks!

Hey Perkri,

You can do all the filtering and mixing in the miniDSP, or you can do all the filtering and send L and R as separate signals to the sub. up to you.

I recommend you use the miniDSP, then you only have to deal with 1 delay.

Also, look at room EQ Wizard or OmniMic to measure and calibrate it.

Cool part is when you learn to EQ the bass and realize you can fix your room modes. :)

EQ can not fix, correct, or eliminate room nodes the nodes will always be there all you will do is add distortion and an even more uneven net frequency response plot.

I have used this HSU high pass filter when I owned a subwoofer with no outputs to my amp!
