What is the difference between these? I know a 2417H diaphragm fits the 2416H, but does it then become a 2417H or is it something different?
I have a pair of SR4722A with the 2417H driver and baby-butt horns that I bought used. One of them didn't sound right, so I pulled the diaphragm and discovered that it must've "got drunk" on one of its' previous gigs. The diaphragm appears fine, but there was a little zinc oxidation (the magnet plates are zinc electroplated to prevent rust) in the magnet gap and slight corrosion pitting on the phase plug.
I have several good 2416H magnets laying around, and would like to use one to replace this. I am almost certain the magnets/phase plugs are identical, but would like to confirm this. Anybody out there able to positively confirm or deny this?
PS- I know that some early 2416H's had 6-7 holes instead of annular slits through the phase plugs. All of my 2416's have the annular slit phase plugs, as do my 2417's. This is what inclines me to believe that the only difference beteween (later) 2416's and (all) 2417's is the diaphragm. And, of course, the right crossover/filter netwrok to achieve proper frequency response, meaning the right driver in the right cabinet with the right network.
