I'm not exactly sure what you are asking, and apparently no one else is, being that you haven't received any response.
But I will attempt to answer your question any way.
If your receiver has multiple crossover settings for all of your satellites, as well as your mains, you should set each to about 1.5 times the low frequency tuning point of your speakers for the most accuracy. Generally 80hz is recommended as a good starting point since it will work with most speakers, and for that reason most film tracks are mixed that way. You may need to experiment a little to get the best results with your particular system. If your receiver has separate
LFE and
sub outputs, I recommend you use the
sub output. This will allow all the bass below the crossover point(s) to go to the sub rather then just the LFE.
