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!

👍✔ at minimal $ costing, and robing any of character at present he's getting now from the Spendor BC1’s

A simple solution is to get a set of filters built into RCA plugs and a RCA splitter on the pre-out. They are much used in car audio setups and work well. Search on eBay for rca plug crossover.

Thanks! Sent Quad an email to confirm no issues with running two separate and very different amplifiers from the single preamp out. Really hope this is a viable option!!!
