Flip stacking used to be a thing back in the 70’s. Two roommates each had the popular Advent speakers and they stacked them to pool their resources. They played them very loud in a small room and they thought it sounded great. Then again, they were on drugs.
you can listen to reason, or you can work with what you got or experiment with cheap used speakers. flip stack experiments. if i was to attempt flip stack i would modify the top set of speaker, cut the top part just above the midrange, glue a wood panel to cover the hole, tweeter is not disconnected and taken out. if the speaker has the tweeter high on the cabinet it could work good enough.
Those drivers can be playing at frequencies low enough where the wavelengths don't interfere with each other. Comb filtering occurs where the wavelengths are short enough that serious phase interference develops between sound emission sources that are producing the same signal. The wavelength of treble frequencies is much shorter than bass frequencies. Bass wavelengths are so long that even the seperation of a couple of feet between bass drivers will not cause a major phase conflict, but that kind of seperation between midrange or tweeter drivers would put the wavelangths many cycles out of phase with each other.
Great answer !

Hi, I sent you a question about a consultation on your website. Not sure if you received
We received it. We all have been Very busy..... we will reply to your request in an orderly fashion. Thanks
Thanks for that articulate answer. So what still puzzles me, is why doesn’t comb filtering occur with multiple drivers in the sane enclosure/cabinet?

Correct. Under 20hz we can't hear. It's that simple jack.
Poes acoustics forever!
