Ok, so some JBL drivers are labled 8 Ohm and others 16 Ohms but there is little or no difference between the two.
Are the 16 Ohm and 8 Ohm versions of the 2405 slot Alnico drivers really the same too?
My recollection on replacing some bullet nose diaphrams a few months ago was that JBL sells both an 8 Ohm and 16 Ohm versions.
