Do not forget Audeze put out Patent-Pending status on their new EL-8 headphone as well.
Make every day a fun day filled with music and friendship!

yes and thats one of the main reason behind folding in any kind of speakers. It increase flexibility. Just like you mentioned even ordinary speakers, especially woofers have flexible folding around edge. Its nothing new really. Im still wonder how Mr Speakers will specify which design will violate his patent and which not. Just to clarify, I really appreciate his work and how unique approach It is in modding fostex drivers. I learned few nice things from his posts. But still I dont see reason to patent this. About Oppo design, their diaphragm is really unique but patent on folding pattern? Btw. I know how ribbon worksFrom what I read the folder ribbon tweeter like the one's I have on my monitor operates in a different way from Dan's implementation. First folder ribbon tweeter operates in the vertical plane by squeezing the air and therefore the air speed escaping from the tweeter can be five times greater than the vertical motion of the tweeter itself. That is the reason that folded ribbon tweeters are sometimes called air motion transformers because of the speed changes.
One of the biggest limitation that I see with the magnetic planner driver is that the middle of the driver can move in greater distance than the near edges of the driver because of the lack of a flexible surround at the edges. For me that sounds a great deal of distortion. For Dan's implementation the whole diaphragm moves together more as one. For me than means less distortion. Even a dome tweeter has a flexible surround moves more like a singular unit.
So my question is why you don't just pleat the edges close to where the diaphragm is fixed, and leaving the central area smooth (like in some full-size speakers)? I'm curious to know how the pleated diaphragm surface affects it's ability to reproduce sound, as it gives the diaphragm surface the ability to expand and contract, and makes it potentially more difficult to control and keep "flat."
I wish Dan would come up with a line of portable headhones based on all that technology. i will keep dreaming
I just love it when a plan comes together.
Got my pair of alpha primes on Wednesday. They are the most difficult headphones to take off. They sort of become an organic part of your ears.

I use both hands and grab around the edges of the pads(not the pads itself) to present less risk of damaging the leather when I take them off. I've had my pair for almost a year now and the leather pads have been holding up really well because I baby them and use the Audeze leather conditioner. I hope they go another 2 or 3 years but I think I will end up replacing them by that time if I am not as careful.
also: if you don't have a stand it helps to fold the earcup inwards to prevent the pads from pressing up against each other which would leave an indentation in the bottom of the earpad that is temporary but could cause a crease if one was not careful

I thought IIcook51 was trying to be funny / humorous...I.e., hard to remove 'cause they were comfy & sounded so good. Funny how people interpret things differently
