As the signal frequency varies from DC to infinity, the phase shift will vary from 0 to +180 degrees. You can also see that by varying R1, the phase shift at a given frequency will vary likewise. If the position of R1 and C1 are reversed, as in Figure 2, the transfer function becomes Application Note 184 Digitally-Controlled Phase Shift Using the DS1669 www.maxim-ic.com

One way to get phase to behave in an active 3 way audio filter is to feed the sound input into a high pass (for the tweeter amp) and also feed the original sound input into a low pass filter for the woofer amp. The midrange signal is then obtained by subtraction (in an op-amp) of both the HPF and LPF from the original sound input.

If you want the most simplified phase inversion, you can apply a DPDT switch to the amplifier output to the driver. This limits you to direct inversion only and you cna even go more low-tech with a pair of banana jacks and a jumper on the back or side of the cabinet. For variable phase, you need to look at the circuit above.
What is "Phase Shifter"? - inSync
https://www.sweetwater.com/insync/phase-shifter/
Phase shifting works by taking the input signal and adding a very small amount of delay to it, and then mixing it back with the original (non-delayed) signal so that certain frequencies of the audio are in or out of phase with each other. The time delay is modulated so the delay amount changes with time.

Variable phase shift for precise alignment Low-pass filter lets you focus the effect + More Features Align your tracks for improved sound The Phazer is a unique tool that sums two line-level signals together using class-A analog circuitry, providing the ability to quickly and accurately phase-align any tracks for improved clarity and tone.
Adjustable phase shifter - All About Circuits

You shift the signal by a delay equal to the difference in distance between the noise source and the anti-noise source. Then, if you invert the delayed signal, it should subtract all the noise frequencies with the correct anti-phase since the delayed-and-inverted signal should equal the inverted image of the noise signal at that point.

An ideal phase shifter in our mind would have perfect phase and amplitude balance from DC to daylight. 7: Power Split with Delay Line. Pro: Easy to Implement, Can be tuned. Con: Only works at a single frequency. This is the trivial case, where you just put the signal through a power divider and then time delay one side. If you have a tunable ...
