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.

Bass management is a HT solution. For music, you should deal with it yourself. If you buy a powered sub it should come with a built in xover, and instructions on how to set it up. There's no reason to make it complicated. People were setting up subs long before there were HT processors with bass management features.
Only thing you need to be aware of is that they won’t play LFE tracks when you attach a subwoofer to the Kefs. They handle a subwoofer fine for music but not for movies. The signal is a 2.0 signal and there’s no proper .1 channel.
