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!

Love the lava lamp in the .../systems/8367. ;)   Must be a system tweak not considered before...🤔

DSP makes the miserable space I've been relegated to employ as a 'listening area' (I'd be hard pressed to call it a 'room') tolerable....so my  bias is obvious, and enough said.
