I believe there are some products in this space. It might be made simpler by integrating dac/dsp and amplifier in the speakers (and the just stream lossless digital audio for playback) -- rather than try and adapt to traditional speakers. It might be the kind of thing that the radical commoditization and continued price drop in hw will make feasible.
Cinemas (and concert venues) do calibrate their sound, here's a sample link that touches on what's involved:
I'm not sure a combined mic/speaker system makes much sense -- it would appear easier to just model what's important: how the sound sounds where the listener is -- which is typically anywhere other than on top of the speaker.
Model a human head w/ears, but mics in each -- and hook that up to a system that plays/records/compares audio. While dynamically adapting (noise-cancelling when there's construction next door, the garbage truck rolls by?) -- I'm not sure that makes much sense. We're used to acoustics changing a bit -- but having a half-decent base-line would probably be great.
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.
Soundsystem techs commonly use a tool called SMART to calibrate a system to the room. 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.
