I have an onkyo receiver that will do the set up for me, but never seems quite right to me. I have the onkyo Tx NR808, emotiva xpa 3, Paradigm Monitor 9's up front, monitor cc-290 (soon to be 390 center), adp 390 rears and ultracube 12 sub. crossovers are currently set as follows: center is at 80hz (thx), fronts are 50hz, and rears are set at 90hz. Does this seem right? I'm trying to dial in the best possible sound and curious what you guys think. Mostly set up for movies. Thanks in advance.
