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!

About $100 to find out - you can order a decent quality custom quad DIN to rca cable from amazon.

does he have a Quad power amp also ???

You do need to use caution inserting active devices with gain into a Quad system. Rated power can happen at .5 v input.

So for an analog solution get din to RCA w splitter and put the analog hipass before the main speaker amp. No EQ but you stay 100% analog.

relatively inexpensive and not complex after initial setup.

must know input impedence of main power amp to calculate/set xover frequency.

best
