While working on another, rather un-related project, some considerations came to mind that I thought should be added to this discussion and measurement of these different drivers. Ilkka did mention that these tests were mostly at less than 10mm of Xmax. Further re-iterating my point that we are comparing executions of various designs and not some theoretical ideal of each design, it should be taken under consideration that both the suspension linearity and low level/near center linearity are what Ilkka really tested in this free-air, near field example. Of these drivers, the LMS does likely have the best suspension. The shape of the distortion vs. frequency curves DO show that the motor is contributing, but there is no separation of either from this preliminary set of measurements.

Let's also remember that the frequency response of the units is NOT the same. Obviously the LMS is behaving very well, but between the other 3, the differences aren't very significant if you also consider at the frequency response differences. I would suggest reserving some judgement until we see some higher excursion and power, in-box conditions. The different shapes of the BL/Le/compliance and other factors will manifest themselves differently, and even somewhat differently in different box designs/alignments. As the old saying goes, it really is how you use it...
