I'd suggest leaving the factory settings. They make the blend in the woofer to the rest work out best.

There is a deeper explanation for the rest of your question. I'll keep it short.

Consider 1000 Hz. There the wavelength is 1 foot. A half wavelength is 6 inches. Assume you have two sources, like two speakers and no reflecting walls. When the difference in path length to your differ by 6 inches, there will be a cancellation. Then add at 12, then subtract at 18, then add at 24, etc. If one driver is reversed in phase, you shift all those by 6 inches. So these anti-nodes and nodes move just a little and occur no matter what you do.

Some or all of this at high freqs can't be noticed in a room with reflections because the reflections pile up at the listening position somewhat randomly,.

Bass works the same way to some extent, but we have to look at the wavelengths. At 100 Hz the wavelength is 10 feet and 50 Hz is 20 feet. Now we really want the bass units in phase because we know the listening position will be equidistant (in terms of wavelength) from the two sources ( the two front speakers) in terms of bass wavelenght. But this also brings up the complicated issue of standing waves at bass freqs.

At 10,000 Hz a wavelength is about 1 inch.

Overall, this is the subject of sinusoids like sound. You have to consider wavelenghts and half wavelenghts. Complicated. Just by way of example, all room dimensions and distances may be about 1 wave lenght at bass driver freqs and 1000 wavelenghts at tweeter freqs.

Now I can enjoy the music without thinking of a problem that was in my head!!

....well....don't discount that just yet. I mean, look at the hobby you're in. []
