By way of background info, I have the following running through the Onkyo: 2 Paradigm Titans (fronts) 1 cc-170 Center 2 Paradigm Titans (rears) 1 PDR 10' sub The distance from the fronts and centers to the rears is roughly 12 feet. What is the optimal crossover on the Onkyo for my speakers with this system for DVD movies: 80 Hz or above 100 hz? Is this affected by my settings on my sub as well -- i.e., if I turn it down to 50 hz isn't this going to affect the crossover settings on the Onkyo? Also, to anyone that has an Onkyo, what subwoofer mode is best for DVDs -- 1, 2, 3? Mode 1 apparently directs all low frequencies from the speakers, Mode 2 directs only low frequencies from the fronts and center, and Mode 3 has something to do with LFE and a 6.1 system. Mode 3 sounds good, but I don't have a 6.1 system right now, so I may be missing out on some bass.
