Kef LS50 - can it handle a subwoofer properly?

I just got a pair of KEF LS50 speakers. As is known they are active speakers and I'm considering adding a subwoofer. They have facilities for a sub but what should I do regarding bass management?, they don't have an  amp, so no such feature, and I suspect the sub will just duplicate the lower frequencies from the speakers and I would like the proper function with the highs and mids on the KEFs and the sub  handling only the lower bass. Any solution greatly appreciated.

You should download the wireless app for your speakers and see what controls they give you on the sub output. If you have a choice, I'd start with the crossover at 80hz with a 24db/octave slope.

Some subs have parametric EQ (SVS Ultra does) so that you can compensate for room nodes.

The sub will have FAR lower distortion at bass frequencies than your Kefs. At 50hz the distortion of the regular LS50 is only 20db below signal level. Even at 100hz, those little midbass drivers have major distortion.
