Tomorrow (8-30) I'll receive my LFM1 and I have some questions about my new speaker configurations. The manufacturers frequency range specs. on my current speakers are Fronts 46-20, Rears 58-20 and Center 56-20. So I have two options as I see it. I can set my 950's xover points to 40 for the fronts and 60 for the rears/center, or I can enable the Analog Bass Management switch on the rear of the 950 and xover all of the five-channel inputs at 80. Does this switch only work in the Analog domain? What is the best xover option for my current speakers? I'm confused about the different choices available. Thanks.
