Fathom 113 no highpass filter

Kal,Okay,yes it can be bypassed but should a person use a ext x-over with the subs even though I have passive x-overs in my 50a's.
I can see using an active X-over with speakers that don't have crossovers in them.

Thanks guys,the fog has lifted somewhat,Kal your right as I use a Arcam AV-8 for movies and I use the arcam's X-over instead of the other JL's(4) which also go thru the 50a's.
For some reason I keep thinking I can't use an ext X-over with the 50a's,the subs have them(which two of them I bypass for movies,my AV-8 has the crossover for movies.You guys are right as I'd just use an ext x-over for the other two subs for the music end of it.
WTF,don't know why I couldn't see that before,to much gear perhaps,Thanks guys.

Hi Bob,and that's a good thing correct, as the active high pass would relieve the mains of bass duty(or most)and let the mains do more of what they like efficiantly,correct.
