I don't think they can be SAM'd. The process of developing a profile starts with taking measurements of the bass driver's performance but those measurements are taken with a laser inferometer which measures the distances the driver moves. I found a description of your Classic 30's online and it included the following statement "…new groundbreaking innovations such as its bass unit, which is integrated into the loudspeaker cabinet and therefore cannot be seen from the outside". If you can't see the driver from outside the box then you can't measure it's movement with a laser inferometer.
It's not so much that SAM doesn't work for certain speakers, the process can only be done with certain speakers. Full range lectrostatics and ribbon speakers can't be done, for instance, because there isn't a bass driver cone and the measurement process can't be applied to electrostatic panels and too ribbons. I think it probably can't be applied to bass cone drivers hidden inside the cabinet because you'd have to disassemble the speaker to get at the driver for measurement and exposing the driver for measurement is going to change the way it works because it is no longer subject to the same kind of pressure loading it's under inside the box so the measurements that could then be made would be invalid.
Sorry but I think you're out of luck with the Classic 30's.
