If you can't locate the source of the low frequency sound when it's
crossed over low enough, it can't be stereo.

80 Hz or lower, with a steep enough xover and sound can not be
localized.

I will say this .. I have a stereo pair of subs and I crossover at 70 and
700 Hz (triamping, yes). Using 24 dB / oct L-R. It is still possible to
localize sounds coming from the subs, though through what mechanism I'm not
exactly sure. It could be that distortion harmonics actually play a role
here. Or it could be the leading edges of the waveforms. Low frequency
transients, heh.
