Assuming the plots are correct (I have found an error with a different speaker) The S1 is one of the most accurate speakers SAMed so far and needs only a small correction whereas the Q1 bass amplitude is very low without SAM, quite a long way from the target, so there will be a lot more and lower bass with the Q1 with SAM which may well exacerbate bass problems in a room.
If I had Q1s (and I am a big fan) I would do what was necessary to the room to get the full benefit of SAM rather than turn it down, personally.
OTOH that is likely to take a very long time and be a pita, it was for me when I had this listening room built...

I agree that it highly depends on the speakers. Fortunately SAM is not a bass boost but an adaptation to the signal to get the precisely desired sound pressure. It is even conceivable that on some speakers presenting a resonance mechanically boost some low frequencies, SAM could even result in what would be perceived as a decrease is Basses, removing the undesirable boosted frequencies.
I don't own S1s but my Armonia share a few common traits with the S1:
* two way speakers
* 7'' bass/medium transducer
* both the tweeter and the 7'' are on the top end and near each other
* both are going fairly low naturally (30 Hz for the S1 vs 33 for the Armonia)

This being said the S1 is a closed design while the Armonia is a ported one.

With SAM on my Armonia, I don't really get a bass boost, although the 32 feet organ pipes are now correctly heard. But my getting a much better accuracy of them.
