Again, It is in Chinese. You do not need to be logged to view the pictures. There are detailed photos about the magnet circuit and voice coil. There is a picture of his experimental Alnico version too.

OK. Fine.
The literal meaning is as commented. Is this correct? Are 2/3 of the production spiders rejected as substandard?
It's quite a relevant question actually.

PS "Typical" of whom? Someone outside the cheer-squad? If a statement is made, let it be defended. That's how it is in democracies.

Thank you for your comments. I will direct your question to L CAO. I hope he can give you some answers soon.

He has not set the price for exporting yet. The price in China yields excellent price/performance ratio.

I asked L CAO and he said the spiders were manufactured by others for him, and only the best were picked to ensure the quality of his drivers.

The price in China is 1500 RMB. with a current exchange ratio of 6.87, it is $218.34 a pair. But the shipping will add an appreciable chunk to that price.

Thanks for the detailed measurements, but with relatively high Q peaks in the consonant and especially in the sibilance BWs, at USA pricing these would have to be addressed before I would want to spend any quality time with them.

Thank you for your comments. Are you referring to the lump between 1KHz and 5KHz before equalizing network is applied? Please help me here because I do not know whether using an equalizer is a good idea or bad idea. Thank you!

You're welcome! I'm referring to the peaks at ~2.5, 4, and particularly at 7 kHz in this plot: http://www.wintersweet.com/permanent/LCAO_equalized

These are acoustic problems that need an acoustic solution (selective doping and/or some form of phase plug and/or ?), so no broadband EQ should be used IMO.
