not a good idea. your speakers are not light beams. while you could add

meaningless and deteriorate the sound.
iiuc, active cancellation is only safe for reflections that are very
tightly coupled to the speaker, and only if the direct signal dominates.
the only thing i could think of are reflections/refractions at the
speaker enclosure itself.
of course, all this is frequency dependent, so you can get away with
quite a bit of trickery in the LF band. but there it ends.
