How do you reverse polarity with two woofers in parallel?

The center woofers have to remain in phase with the main speakers.
In those speakers the tweeter is not in the same polarity as the midrange.
This is a 12dB three way design, and the mid polarity is opposite that for the woofer/tweeter.
See post #4.

I tried flipping the mid polarity and it didn’t seem to help. Just different dips in different places.
I flipped the woofer after and that seemed to do it. It’s flat now.
I don’t know how I could mix up that. It only has one crossover part but flipping it seemed to fix things.
The mid, while not pretty, is shown. I attached this onto a little mdf plate and it’s in the speaker a little hard to take a picture of but this is it’s layout

because the mids and tweeters still have to be the same as each other.)
Clarification: the same as currently, whichever polarity that is. If you change the mid, the tweeter should be changed as well so that it retains its relationship with the mid.

However for whatever reason the centres may be different and it would be best to find out exactly why.
