I have the 522D's for front and back and the matching center channel along with the big 12" sub. I had been using an inexpensive Onkyo receiver (HTIB variety) but just bought a Pioneer VSX-1020-K and thought it time to make sure the sub is set up correctly. I am primarily interested in movies with part of my upgrade being a Panasonic DMP-BD85K blu-ray player.
What is the correct crossover frequency and how do I know how to adjust the phase and other controls on the subwoofer? I know this may be basic stuff for some so thanks for your help!
We recommend 80 Hz as the crossover point for the sub and then 80 Hz also for your 522s so you get the smoothest blend between them.
As for the phase control that is used for room correction, so no way for me to say what the best setting will be for you. What I recommend is that you sit in your primary listening position and then have someone else slowly turn the knob. When you get a nice tight and loud low frequency response from the sub in comparison with other positions for the phase control you will have optimized the phase setting for your sub.
I recommend using the auto setting so the sub clicks into standby when not in use so it doesn't consume as much power.
Other than that the only other thing to play with is the level knob which you will want to set at a position so the sub plays at a volume that matches the output of your other speakers, unless your preference is for more or less bass.
I hope that helps but please let me know if you have any other questions, thanks!
