Can you clarify exactly what Devialet said? The point being that SAM operates from 150Hz downwards, it does not work over the entire frequency range.
From the Devialet white paper:
"SAM is effective on lower frequencies, up to 150Hz, yet its effects can be heard throughout the audio range"
So quite definitively, SAM operates below 150Hz. Indeed, I have watched some 3 way speakers being SAM'ed at a Devialet event, only the bass driver was measured, so it cannot materially influence the tweeter.
I suspect that Devialet were just reiterating the "yet its effects can be heard throughout the audio range" line, rather than implying that SAM itself operates above 150Hz?
