Fathom 113 no highpass filter

I have read alot of people using an ext X-over on their JL subs,but they don't say if their main speakers have passive
X-overs in them.
My Q is wouldn't an ext X-over interfer with the passive,
even the JL manual states to use an ext X-over for the subs,
just a bit confusing.
I use Revel 50a's(mains with passive Xovers in them), 2xf-113's for the music side with Bryston BP-26 pre and 28B's for power.
Any thoughts,thanks.

The f113s have a LP crossover but it can be bypassed.

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.

I would yes (to an external crosser) just for this reason. Why send that low bass power to your speakers? That would keep a little extra power for the mid bass on up in the mains. The purpose of internal speaker crossovers is to separate the needed frequencies for the different drivers.

That being said I personally do not use an external crossover yet for my sub. Someday when the funds permit I would love to get one for the reason I stated.

Just my opinion
