Using the removal of the
plates as an excuse to open up up the cups and take a look inside, I did so with appropriate supervision. All photos in the
album.
Slid the pads off the mounting ring, noting the indentations from the three screws, which I removed .
Another reminder of the futility of fancy sixteen strand silver plated helix weave 12 AWG superconducting cables. These thin short cables are attached with a pinch of solder, making it difficult to safely rest the two pieces without putting them under tension.
There are three small black rubber washers between the mounting place and the cup.
There appears to be a vented disc brake in this headphone.
Inspected the thin back foam with the hole in the middle and the two bolts securing the plates.
Unbolted the plate with a star driver which fit the hex bolts, removing the tiny nuts from the foam inside the cups with tweezers.
There are three small black rubber washers between the mounting plate and cup.
One down, one to go. Another town and one more show.
Close-up view of the grille with more light.
Nuts and Bolts attached to plates and saved in a small bag for posterity.
Final inspection.
Naturally I intend to imagine that this change will radically improve the sound, making it holographic with sparkling highs.
