From my understanding, an LFE input bypasses that powered sub's internal low pass crossover which you may need.
I use a pair of twenty year old Eosone subs in the HT with left and right inputs designed to provide lots of flexibility and single sub use. Those in conjunction with matching outputs to provide a high pass signal out for a main's amplifier should you not otherwise have that capability.
In my case, I use the LFE output from the processor and just use one channel input. There's no need for summing discrete left and right content nor providing high passed stereo output. The processor outputs to the Emotiva amp driving the Acoustats use it's high pass crossover.
I set each sub's crossover to the highest setting (200 hz) and use the processor's DSP to fine tune the optimum low pass.
