Congratulations and welcome to the family!
Couple of questions. From what I've read, seems like it is best to use line in inputs and set cross over to 80 hz.
Line in allows you to cascade crossovers for more rolloff (less highs in the sub, less lows in the mains) and access to more of the controls. However, most AVRs handle all that stuff automagically, so unless you know how to tweak things I'd just use LFE and let the AVR handle things at first. You can always change later, but most of us simply want our new toys to be playing away without hours of fiddling or weeks (plus) of learning. I wouild use LFE, set the crossover in the AVR to 80 Hz, and listen for a while.
How does this work for a pair or speakers (used for surround highs) that only go down to 110 hz? Or am I limited by the highest value?
Depends on the AVR or processor. Some allow you to set independent crossovers so you could set the main L/R at 80 Hz and surrounds to 110 Hz or whatever. Others (Pioneer is the main one I recall) have a single global crossover. I'm with Soulburner on that; I'd use 80 Hz and integrate the sub with the L/R(/C) speakers and not worry about the surrounds (effects ) speakers too much. Again, can always tweak later.
Last question, is it safe to assume the sweet spot of my previous sub (pb1000) will work for its fvx15? I am currently in posts from July 2016, I still have a lot more to read if it hasn't been asked before. Hopefully I'll be current before the sub gets home. Thanks.
Should be, though differences in output and frequency response may mean different room modes and SBIR effects are impacted. I would certainly start there if you've determined it is best.
Skim the thread, read the setup guides, and ask specific questions. Yes, we've heard them all before. Yes, we'll answer anyway.
