12db slopes will cause a 180 degree phase shift, and 24 db slopes will cause a 360 degree phase shift… this assumes the driver has a perfect flat phase and acoustic response in the first place or is eq’d to flat (with no phase issues to complicate the drivers phase in the first place…) and then has the crossover applied

I have a question about phase shifting. I have a tube preamp with y's coming out of it, 1 or going to full range amp and the other pair going to subwoofer amp with dsp. If I send a test tone set to sweep from 10 hz to 200 Hz and I have an oscilloscope with 2 channels, I can watch the phase shift.
Phase shift and its importance in audio amplifiers ...

It's often more useful to work out the phase shifts in terms of group delays : for example a 360 degree phase shift on a 200Hz signal is 5 ms (1 full cycle) and a 1080 degree phase shift would be 15ms. Now consider the speed of sound : about 1000 feet per second, so one way to delay the other signal is to move its speaker back ... 15 feet!

If two loudspeakers generate the highest air pressure at the same time (their tweeters vibrate synchronously), the phase position is 0°. If one speaker generates the highest air pressure, while the other speaker generates the lowest air pressure, the phase shift between the two is 180°.

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

Example 1: Left and right channels in phase. But if one side of the stereo signal is reversed, as shown in the second illustration, the signals will cancel each other out. In fact, if we were using a pure sine wave, combining both signals out of phase would result in silence, since the sounds would literally cancel each other out.

The phase shift switch allows you to select 0 or 180 degrees. The phase shift switch can be used to prevent phase cancellation of low frequencies that are output by the subwoofer. Matching the phase of your subwoofers with the phase of other speakers in your system ensures bass response does not suffer due to phase cancellation.
