P.S. james444 is right the red ring was just a voice coil, I unraveled a bit. Sennheiser did something cool here just need to figure it out.
electrical current playing with magnetism, think of electricity as being the same as the fuel in a piston...So can you explain how it vibrates to make sound? I really don't have a clue what's moving. My only thought is that the magnet is so powerful is that it's making it seem inflexible, even though applying power will cause it to vibrate.
OK, I put two drivers over each other and smacked it as hard as I could with a hammer over and over again -- and this is what happened. One driver separated into a red ring and the base part. The base part is hard metal and won't break further.
What does this mean? Is the red ring like the ring in the HD800's driver? This clearly isn't using a flexible diaphragm like a traditional speaker woofer.
The red ring is the voice coil. Here's a detail enlargement taken from one of your earlier pics:
I know that. I'm asking which pieces move. It seems like one solid piece.
Take another look at my enlargement. One can clearly see the transparent diaphragm and the red voice coil underneath.
The diaphragm itself is usually very thin and you likely destroyed it while smacking the drivers. In your topmost picture, it seems like fragments of the diagram might be still attached to the voice coil. However, picture quality is too poor to tell for sure.
Here's the bottom view of a headphone driver diaphragm with voice coil attached. In IEMs, everything is a lot tinier and more fragile though.
OHHHHHHHHH. The diaphram was that (solid) plastic thing that I destroyed (I definitely did see remnants of it; you can actually see some in the pic). Thanks for figuring it out. The power of crowdsourcing; eventually someone will get it.
where did you wind up buying from?
Hi Alex
Taking my chances with Amazon, at least they have a 30 day window, I'll also to do a direct comparison with my knock offs and post photos and impressions.
Amazon warehouse deals? There is a very good chance you'll get a real one that way.
