Happy Holidays everyone!! I installed a new HT system for my sister yesterday. It was my brother-in-laws Christmas present to himself. New speakers included 4 Paradigm Cinema sats, center channel, and the PDR-10 sub. New receiver is the Pioneer Elite VSX-33TX along with a Toshiba DVD. A nice step up from what they had. What crossover should I set on the receiver? Choices are 80Hz, 100Hz, or 150Hz. (I have the subs cutoff frquency all the way up at 150Hz.) The low frequency extension on the Cinemas is 80Hz. The frequency response (on axis) is rated at 115Hz-20kHz (+/-2dB). Thanks for your help!
