I'm considering the types of 2nd order 2 way crossover to use in a new setup.
Most designs suggest reversing the polarity to negate most of the phase shift.
My question is , is that for the woofer only or does the tweeter polarity need to be reversed as well? Does this apply to the crossover or speakers only?

Tweeter phase is a very moveable feast. It so depends on the alignment and offset between the woofer and tweeter, which most speaker design simulators allow you to adjust.
The object of the exercise is to keep the two driver's phase tracking near crossover. This makes for good imaging and avoids suckouts in the frequency response.
On a conventional baffle you normally wire in phase. If you time align, as below, out of phase is going to work better:
It all greatly depends on how far apart the acoustic centres of the two drivers are. Hopefully a good kit design will have done all this work for you.

An externally hosted image should be here but it was not working when we last tested it.
