OK....so if all these characteristics make for the "perfect cone" why pray tell.... how does it function as the "perfect" surround....which 'requires' a flexibility like no other?...........Two aspects of a material with opposite requirements. Just folding such a material into pleats does not alter its characteristics so radically. My guess is it looks "cool"........as to function.......I think it would have not "looked the part" if it had a 'known' surround.

Rick while I'm sure there is some truth to what you say. I believe overall you are mistaken in your POV. To explain why I'm saying this let's start by taking a look at the uber-expensive prices of some highly regarded & highly sought after ---{at least by those who can afford them}--- drivers that many audiophiles, even full-range driver aficionados like myself, really do refer to as "Full-Rangers gone wild" the Feastrex line of single full-range drivers! Much of the Feastrex "sound" is attributed to their usage of Washi paper in their cones! I'm curious, did you know that making Washi paper is considered by the Japanese to be an artisan handcraft? Did you know there are many different varieties of Washi paper?

The type of Washi paper selected by Feastrex to be used in their main cones ---{this type of Washi paper is known as hosho-shi. It's pronounced phonetically as “hoe-show-she”}-- is very strong and made from the inner bark of type of Mulberry tree in Japan. Now since we're discussing Sonodyne's material of choice and Sonodyne is in Korea, I suppose I should stick to talking about Korean Hanji paper, not Japanese Washi paper, right? Well Rick in case you didn't already know this. I'll inform you Korean papermaking started soon after its birth occured in China. As would probably be expected, at first this Korean paper was crudely made. The Koreans made this early paper (called maji) out of hemp and ramie scraps.

But I digress, I was talking about Hanji paper. Well the origins of Hanji paper in Korea is believed to fall somewhere between the late 500s BC and the 200s BC ---{Hani was eventually developed to the point that it was renowned as being the highest quality paper available in all of East Asia}--- and in 1931, a piece of hanji paper was found at an archeological dig at a tomb site from the Lelang period (108 BC–313 AD). Now this is where this tale really start's getting good. Hanji, like the Japanese Washi, is also made from the inner bark of a type of Mulberry tree! But this is a Mulberry tree that's native to Korea and grows well on its rocky mountain sides! So from that POV these Sonodyne SD-855 eight inch fullrange drivers ---{as well as Sonodyne's other Hanji full-range drivers}--- could be viewed as being the poor man's version of the Feastrex! Granted the Sonodynes do NOT have the awesome motor structure of the Feastrex. And there's no doubt that those field-coils play an important part in the sound of the Feastrex drivers, but at 800,000 Korean Won or it's $716.91 conversion into USD, these Sonodynes cost less than virtually every Feastrex and actually cost a lot less than many Lowthers, Voxativ and even a couple of Fostex fullrange drivers do!

So Rick in this light I'd say that compared to many other full-range/wide-range drivers these Sonodynes aren't very expensive nor are they candidates for Full-range drivers gone wild...

Radio you're quite correct. No one what's to be the first to take the financial plunge. If things turn around for me financially I'd do it, but with my health issues don't hold your breath waiting for it to be me that's first!

Tom, I would suggest that you keep your hands in your pockets!
Lets face it, drivers have changed very little over the last 80+ years, just a frame, magnet, coil and cone.
What is this guy offering, I only see images of the fancy cone and none of the magnet assemblies. Perhaps he is just buying inexpensive Chinese drives and tearing out the cones?
Just selling on ebay does seem to be a little hobbyish, like making bird boxes.

Terry I wouldn't buy the Sonodynes from anyone but their factory in Korea or a rep of that factory.

How many speaker manufacturers or box makers have come and gone over the years it must be many, many hundreds? How many speakers have stood the test of time and are still highly regarded, perhaps a couple of dozen, if that?
It's all about marketing and the more you charge for your product the more you can spend on marketing.
Most speakers are pretty much the same, only the price differs, thats my thinking.

He might have legal problems selling any other way since there is an older indian speaker company which is also called Sonodyne. They are well-established and sell in over 40 countries hence it may well be illegal for korean Sonodyne to officially sell anything speaker related under that name internationally.
The original Sonodyne predates the korean one by 30 years.
