Everything I hear about the Rythmik subs sounds great. However, I am troubled by the THD chart as measured by Ilkka (4th chart in the link below). Am I interpreting it wrong?
PS- I am actually looking at the F12G, but this is the closest I can find. Would there be differences (aside from the GR driver extending into higher frequencies)?

I am not sure what the difference between the F12 and the F12G drivers are exactly, but I might assume that the F12G improves on more than just the higher frequencies.

Thanks Jon.
Different manufacturers and different materials - you're probably right about that. I guess the only real commonalities are the servo system and cabinet.

Note Ilkka's comments in this post regarding the THD performance of this sub:
