One channel of a pair both in December 2015 became open circuit recently.This occurs suddenly and no physical abuse by heavy loud music .
This is traced to corrosion of the coil wire at the glue junction. See the whitish powder . The speaker was subsequently repaired locally
Please see picture.
Has anyone else has similar experience?
Any advice on how to avoid similar fate to the other driver?
I measure 6 R across the terminals for both pair even though the speaker is spec at 8R. Is this usual ?

I don't see the whitish powder in your photo, but this type of failure has been seen in other drivers. To answer your second question, 6-Ohms DC measured from an 8-Ohm voice coil in a magnetic gap is fairly standard.
PTSD fuel - I had to pull a JX92S (sister to the Eikona) from a transmission line to check the condition of the adhesive.
It looks OK, the dark spot is shiny solder. You'll notice the marks from the tinsels rapping against the cone from the past run-in process.

This is what l suspect. I am rather disappointed by this as this is my first encounter with my most expensive full range speaker .
I suspect the other side may fail soon
