Nitin,
If you have a chance would you check the serial numbers on those cabinets. I would be interested to know the serial numbers are close or maybe even sequential. I would have to think that, as was pointed out, there may have been a short production run of marginal diaphragms.

Ditto the bad run of diaphragms theorem. Similar issues encountered years ago with B&C 750's in V-DOSC. Finally traced to the location of the diaphragms in the curing tray in an oven.

Personally I would like a more robust mechanical + solder connection, but this likely affects response.

I am still resoldering the leads on the voice coil wire once or twice a year from my DE85s.  Absolutely nothing wrong with the diaphragm or voice coil, just a solder connection the comes undone every once in a rare while.

This reminds me a lot of the problems we've had with 4886 HF failures, that seemed to happen with no reason.

Ditto. 4886 and the 825.

Replacement drivers on both systems now seem to work well.
