I'd expect to see a labyrinth or a tuned cavity or something like that. And twin peaks? That's just scary. Any guesses, based on the photos of the innards, where these might be?
.
Double cavities... one behind the driver, one in front of the driver (pads-baffle-ear)? Not a unique idea.

Did anyone here buy that EAH-830 that was on the auction site recently?

Hi. I´ve just started to collect vintage headphones and have been looking at these abused TECHNICS EAH-830 listed on ebay. It´s a cool design and I´m sure I could bring them back to life. Just wondering, do you think the drivers are fried and if so is there any way to save them using a conductive paint pen or similar? From the pics it looks like the cans are metal under the usual technics color, correct?
