Does anyone know if the 2251J and the 2251J-1 are the same driver? They are both 10" midranges. If there is a difference, then what is it? Thanks!

Hello Steve,
I recall from this forum that the 2251j-1 adds aquaplas and a mass ring, maybe 10 grams for the aquaplas and 10 more for the mass ring.
Best Regards,
Tom

Thanks, Tom. I understand that there is also a 2251J-2, which I was told has the aquaplas. Maybe there really is only a -1 and a -2, and no plain 2251J designation? Or are there 3 drivers?
