The only -I mean the only - difference is the sticker they put on it..... I know, because I tested both the original , and the OEM version. Almost all big name brands source their drivers from China. That is the (sad?) truth.
I absolutely agree with this. All one has to do it look at the Oppo Bluray player. About a dozen A/V companies have licensed its design, and made subtle improvements, and priced them 3-5 times Oppo charges. It is made in China with Oppo's approved specifications.

Let's throw in video panels and all sort of audio equipment into that same soup.

The tweeters on the photos have nothing to do with ScanSpeak, since they are Vifa XT25 ring radiator clones. Their parameters match the original within 10%, in fact (IMHO) they might even sound slightly better than the Vifa-s. Mechanically idistinguishable (well, except the non-gold plated terminals), same magnet size and strength, same pole pieces, faraday ring, resonant chamber, etc. So actually they are pretty good. BTW, I have about 70 pieces to sell, due to a failed order from a customer.....

The Le of the OEM is higher than the scan original, but is still relatively low so there could very well be copper or alu rings in the gap.

I would assume that even a knockoff cannot use the SD motor as that's scan patented, so the two wont be identical, but the cone seems as well controlled as the original and the progressive spider's there. It probably performs very well, a scan it is not though, but it could still have low distortion. For the price, if the motor's as good as Peerless' exclusive range, it's certainly not a bad deal. I'd like to see comprehensive and well executed distortion sweeps though.

You are forgetting that patents aren't worth the paper they are written on in china. In fact there is a trend to not patent things these days as the Chinese are less likely to work out how to copy it if they don't have access to a patent telling them how it works.

Even if they had access to the sd1 designs, it would probably be far too costly to produce the tooling to make them in low volume,, unless they were manufacturer of the motor in the first place. Its likely that scan distributes parts production to prevent complete knockoffs being produced.

>.< What is the world coming to, but as a side note I am all for getting products that don't have someone's idea of excessive mark up added to it.

back to tthe original question... has anyone tried these out?
Compared to the 15w's I have there's a LOT of severe differences, they look like 'aesthetic copies'... which means I'm guessing they sound awfull. At 60 I'd give them a punt, but 130 a pair without any proof of quality is SERIOUS money in my books, what do you guys think?

I've messaged the seller with a 'put your money where your mouth is' statement - Told them to send a sample for review and advertise it.

Out of interest, can I get a shout here from anyone who'd want to buy them if they turn out to be as advertised? Maybe we can nuudge zaph...

Supposing the sample is good, do you have confidence that the next batch, or even the next one will measure the same? China isn't known for their strict quality control.

Actually look at Airborne's pdf's they use "SD-1" motors in some drivers. I don't know if they are ScanSpeak's SD-1 motors. Also some drivers look similar to the SS 15W.

These are garbage. Don't bother. I bought a kit with a pair of these in along with some vifa tweeters(which are ok).

The ones I had looked even worse than the ebay photo, think they picked out a half decent looking pair for the photo's

These definitely don't use any original ss parts whatsoever. No grasshopper basket, no symmetric drive motor, no faraday ring, no variable rib spider.

Like all copies they've paid the most attention to the bit you see - the cone but even that's not ss either.

Save up for real ss or buy one of the other great drivers out there. Avoid these.

I'd bet, if you held one of our "name brand" manufacturers(ScanSpeak, Vifa, Eminence, Celestron, Tang-Band,....Etc, etc.)....'feet to the fire'....they would grudgingly admit to Chinese made. It just doesn't make sense to hire workers @ $20+ Hr to assemble drivers in the States, Canada, UK or any other "First World" country.....when it can be done elsewhere for literally pennies on the dollar. Now, if these factories decide to crank up the assembly lines in the dead of night for "their" versions that's a different story.
