I have the same unit. I have the phase set to 0 and the receiver toggle set to 5.1, 6.1, 7.1. I think the receiver toggle sure turns on/off the subs crossover filter. As far as I know, my receiver is handling the crossover for me. What is your experience with your settings at this point?
Trying to figure out what phase 0-180 does.And whats best.
What is best will depend on how you have the sub set up in your environment. Typically, if you have the sub up front, 0 may work better, but not always. Switch it back and forth and see which one sounds better / produces more bass.
