Hello Massimo, I stuck a clip on the grid of the 850a Pro and realized that there is a sticker in the middle on the sides, probably that there was originally a cushion. Do you know ?
Best regards.

Hello Guil
Originally there is a sponge but it is not important on the sound. On the other hand, it is very important to have the 4 fixing pins intact. I have available identical rebuild from a turner, in case you have one broken.
Best Regards
Massim
Hi Massimo, thank you for your answer and proposal. The 4 pins are intact but 1 went out of the grid, I recolved it with some neoprene glue.
The sound is now a little different but i know a have to wait a few days the glue is dry, the 850a Pro are very transparent and i can ear every change.
