Fact is @brianlucey, that your MMThree Exact is an active speaker, and you don't seem to understand this. The woofer section is powered, and shapes the frequency response of the amplifier to enable a very low -3db point. Your primary monitoring speaker is an active speaker. That seems to negate your views on active speakers.
For the Trinnov processor, one of its primary functions is to measure and correct the speaker response. It injects test signals and measures from its output through your amplifier, through the speaker, to its measurement microphone. It then corrects frequency errors, and phase errors of the combined system. It does this independently of the room correction function and surround decoding. A similar process is an aspect of a fully active speaker, but the manufacturer can do it more accurately as they don't have environmental interference in their measurement, worry of component drift, i.e. from a tube amplifier, and then can directly control each driver, not just the system as a whole.
