The speakers have the following specifications regarding the Phase and Crossover.
Frequency Response (Phase) = 44Hz–22kHz ±3dB on reference axis
Crossover = 150Hz, 4kHz
Here are my questions:
1. Frequency Response is referring to Phase, correct?
2. My Pioneer VSX-522k seems to only have the following phase settings, 200, 150, 100, 80, 50. I read that your receiver phase should be set to be less than the speaker's Frequency Response capability. Since mine only goes down to 50, would setting it at 50 be correct?
You are referring to the frequency response of the speakers, and the crossover frequency of the receiver.
Phase is something completely different, and is caused by two signals of the same frequncy playing back at a slight difference in time. The term Phase shouldn't be used here.
The Pioneer VSX-522k only has a single crossover point that is applied to all speakers that are set to "SMALL". What that means is you will want to choose a crossover freqency that is higher than the worst frequency response of all of your speakers including the Yamaha HTIB speakers. Without knowing the model of the speakers my guess is this is somewhere between 80-150 Hz.
You may get better overall sound and be happier by setting your 684 channels to "LARGE" which will cause them to play back full range and then use 100 Hz for all the other speakers. Play around with the settings and listen to it an see what you think. Find what sounds best to you.
A lot depends on the quality of the other speakers and your subwoofer so it is hard to say what setting is best. From my experience with other HTIB speakers and subs you will probably get the best results by setting the 684s to "LARGE" set all the other channels to "SMALL" then choose a crossover of 80, 100, or 150 Hz.
Also depending on your room configuration your system may sounds a lot better by turning off and removing the center channel. When you do this the sound from the center will be sent to the two front speakers (684s) which are much better speakers and match eachother.
