Using random SAM profiles on unSAMable speakers

[Jean-Marie]

My concerns would be the same as those of Jean-Marie of damage if applying a SAM profile wildly inappropriate for your speakers.

I just picked up on this and am curious as to what SAM does that might harm a different model speaker?

Isn't a Devialet running SAM pretty much the only amplifier that has awareness of the speakers drivers and their limits, and so a speaker has to be able to stand pretty much whatever is thrown at it - assuming someones manning the volume and is vaguely using common sense.  I think my Facts have some kind of braking mechanism?

Or is this completely wrong?  Apologies for my lack of knowledge!

My understanding is that SAM is driving the speaker in acceleration under 150 Hz. Which means that it is calculating which voltage needs to be apply instantaneously to get the right acceleration. it will do so within the acceptable envelope of the given speaker.

To illustrate with a extreme example, if you feed the amplifier a SAM profile with a very low efficiency speaker but supporting a lot of watts, it can, even under very low volume, apply very high power that would shred apart a much higher efficiency speaker.
