Putting them in the speakers just limits the amount of extra things you you have to install, the idea is that in initial setup each speaker goes through a test pattern while the other speakers stay silent, and this gives you position of all the speakers and the acoustic properties of the space they are in.
Though if you also have some extra microphones, then you can do dynamic adjustments on top and even account for people moving through the space so that they do not block sound or even so a stereo recording follows them around.

It basically does impulse response measurement by blasting pink noise through a feedback loop and putting in various phase adjustments until the room has been cancelled out. It's a very delicate technique though. When you're talking about phase-aligning soundwaves you're sensitive to sub-millimetre alignment of your transducers.
