Since you didn't get the appropriate powered sub for this application,

can build an active LP filter for the input to the Sansui or a passive
LP for around 50Hz.

Thanks. Does anybody know a good site explaining how to build this kind
of filter? I have some electronics knowledge, but only to a general
physics A- level (and that was took 3 years ago)

Try the Wilmslow Audio site, at http://www.wilmslow-audio.co.uk
They may have a suitable design available, and if not they have a
reasonably priced design service for crossovers. The final design will
depend on what order filter you want, which will depend on your main
speakers.
