FR with SAM 0% is exactly the same as without SAM - what cannot be seen on FR (and what can be easily seen when subwoofers are being integrated) is phase shift which SAM introduces in both cases - 0% and 50%. It would be interesting to see phase and impulse measurements with REW.

It's interesting that the results with SAM off and SAM at 0% are identical apart from the phase correction. Floyd Toole states in his book "Sound Reproduction - Loudspeakers and Rooms" that phase correction in the bass can result in up to half an octave of bass extension and I was interested in seeing whether there was any extension at a setting of 0%.
