External crossover with JL F113

Greetings all,

I’ve been on an upgrade binge lately, and just scored a pair of F113 V1.  They will be supporting Sasha DAWs, which I expect to be installed in a couple of weeks.  The dealer who will be installing the Sashas also happens to sell JL Audio; the Wilson approach to positioning speakers is gonna be cool to experience with the subs in place.  One of the things about which I think (obsess) while I’m in the sweet spot listening to the rig is “can it sound better if I get a little more toe-in, elevation, distance from the wall etc...”. That’ll be put to bed at the end of this.

I’ve read tons of reviews on the Fathom 113s, and in a few they were supplied just the low pass signal from an external crossover.  I have a Marchand XM66 (if you ever need a crossover get one of these; call them and Phil Marchand will probably answer the phone).  A goal of the upgrade binge has been to simplify, but substantially improve my system.  The move to active subs to replace some passive ones I have (a pair of Revel Sub-15s), gets a pair of digital amps and speaker cables out of the signal path for the subs.  I’d also been planning to run the Fathom 113s directly from my preamp via XLR, and get the crossover out of the signal path.  The Sashas will run full range from mono amps, not thru the crossover.  Cabling amongst the various components is Stealth Sakra/Indra.

Any thoughts on which is better:

Keeping the crossover to send low pass signal to the subs or removing the crossover and sending a full range signal to the subs to simplify the signal path?
