Well the effect of SAM is to correct the cone movement from 200Hz down.
I don't want to get too technical on a forum such as this, but basically in a loudspeaker the cone is never exactly where it should be had it perfectly followed the "instruction" of the amplifier signal. Devialet measure this deviation and produce a correction which means that the cone actually is where the input signal determines it should be.
On top of this they measure voice coil temperature and the safe travel of the bass cone. This is then mapped in to make sure the drive unit is always kept within its safe limits.
This does, of course, mean that the correcting effect can be partially over-ridden by the safety side of the software, so if one is trying to play a massive organ piece at high volume with, say LS50s, the bass -is- corrected for frequency but the level can only go up to a non-damaging level.
The effect will be very small on speakers which are very accurate and full range already, and are more likely to reveal room problems.
