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!

Mostly valuable opinions here.  I, too, am investigating an actual active X-over to take everything below out of the signal to my amp and LRS's and send it to at least @ powered subs.  Those subs can be positioned to reduce nodes.  The miniDSP HD has a x-over, HPF & LPF and by plugging in a PC, Mac or phone app, I believe, 25 bands of parametric EQ.  My concern is if the sample rate of this device will nullify the resolution value of my DAC.  The miniDSP HD apparently is 32bit & 192k.  The new $60 dsp from Parts Express doesn't say.
