Sub phasing

[khenegar]

What is the correct Phase setting for the depths using the summits, I have 2 depths and 2 summits 0, 90 or 180? How do you know if you have the correct phase? thanks

Before you do this, does your MC12 automatically set distance settings for each speaker? If it does, there should be no need to fiddle with sub phase. If not, here's a simple method I've recommended before. Downloadable frequency tone files are easily found on the interweb.

To set phase on sub x, turn off the main farthest from the sub, and any other sub(s). Reverse the phase on either the sub or the main (not both!) by reversing the speaker connections. Sub and speaker are temporarily out-of-phase. While playing a tone at the frequency of the "crossover", listen at the point midway in space between main and sub while an accomplice slowly adjusts sub phase. At ideal phase, the tone should become essentially inaudible as the sub and main cancel. Repeat for other subs, as necessary, always using the main closest to the sub being adjusted.

When you're done, be sure to return the reversed speaker connections to their original, in-phase condition.

There are better, more accurate ways to do this, but they require the use of room measurement setups e.g. REW/Omnimic/XTZ.

The correct setting depends on your room and placement. You've got to do it by ear. Or you can take some measurements at each setting and see which one gives the best response.
