110 or 120 (if possible), low frequency response can be overstated. Mine hit 75hz but are attenuated at that frequency, so I use 100.
Define "satellites". If there are wee cheapo 2.5" single drivers from a HTiB, they may need as high as 250hz. Bookshelf sized speakers might be safely run at 80Hz. And listed low end range is wildly optimistic, and probably might be accurate at 1 or 2 watts RMS, but at any significant volume, they could be damaged at the listed low end range. A simple test might be to turn off your sub (assuming you have one), and play a midbass heavy song (think bass guitar range), and listen for distortion as you crank up the volume. Play at various cutoff settings and see what sounds good without distortion.
just test it out and see what works for you best. i know after i ran audyssey i had to change my crossover to a lower number because what it was set at initially was not nearly enough bass that i wanted to hear, and this is with the audyssey that calibrates with dual subs too. try watching a scene you like with different settings. i think i ended up keeping mine at 80 and it went to like 120 after calibration.
I'm trying to hit that G spot with the levels and crossover setting. I want my ears to spooj!!
But if I changed it to 80, doesn't that mean the satellites will take more stress?
your not missing it, its just being routed to your sub
stuff 100hz and below is mostly bass and midbass
