JBL 2405H on JBL EVEREST DD55000

[microseiki]

Need advice.
I need to change the diaprhagm of the 2405H of mine JBL EVEREST DD55000.
Is the diaprhagm a 16 Ohm or 8 Ohm
According to the leaflet is a 8 Ohm system, but there is a schematic that shows a 16 Ohm .
which should i order, the D16R 2405 or the D8r 2405

As far as I know they are the same, there's a thread about this: http://www.audioheritage.org/vbullet...or-Comparisons

According to the technical manual is the D16R 2405

There is no D8R2405 to the best of my knowledge, if there ever was I have never seen nor heard it even discussed.
The measured impedance of these in the passband is about 10.2 - 10.4 Ohm regardless of what the foil-cal / sticker says.

That's what I remember also, I was not sure about D8R or D16R but I knew there was only one.

I think everyone is right.
