Means the two waveforms won't be 'mirro images' so won't null.


An important point.


Again, what odds to anyone prepared only to pay as little as possible
for 'budget' speakers?

None. Just that the user won't be hearing clear stereo imaging.


That's a presumption I presume?


No, not really. The quality of the null you get when you wire the
speakers out of phase is a good indicator of the quality
(locatability, if you like) of the stereo image they can produce. A
setup that produces a solid central image in the centre when playing
mono will also produce a reasonable null with out-of-phase mono. The
same goes of course for all the other image locations between the
speakers.
