I am trying to figure out which crossover settings to use on my Onkyo TX NR-646 receiver. My Fronts are RP-250F, RP-440C center, RP-240S rear surround, Yamaha YST-SW216 10" 100 watt sub and Onkyo SKH-410 Atmos Speakers. And what are the best settings n this receiver for watching mainly action movies? Thanks
