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.
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.
