Dual Subs set up advice


Can anyone give me some advice on best practice to run dual subs? I have two Martin Logan Descent i subs for a strictly two channel system with ML Prodigy mains.

My options are:
Speaker level in
RCA in (sub has both left and right in for single sub use)
Balanced XLR (LFE)in (only one XLR in)

I am running the Sonic Frontiers Line 3 which has both balanced and SE outputs.

As of now, I am running them from the 2nd post on my Krell 300M amps but was wondering if it would be just as well to run SE (rca) left out from preamp to left sub in and vice versa for the right. Or, go balanced #2 outs (balanced #1s used for amps) to the single (XLR) LFE in on the subs.

Thoughts opinions?

I have dual NHT subs, and related NHT SS dual amps. I have three systems, each with separate pre amps. One has dual amps outs, one a sub out, and one with only tape outs. I route all of the outs to a Chase RLC remote controlled unit as a switcher that goes to each of the NHT amps. I do not use the NHT amps to feed the three different sets of speakers that I use individually, all driven by tube amps. Since the line out of each pre amp is different, the Chase unit's remote is used to adjust the output of the NHT sub amps. Works well, gives a lot of flexibility. For WAF purposes, each sub is in a front of the room corner, but I have been testing various other placements. Nothing finalized yet.
