Look at the size of the motor:
RCF?????280?125?15????????????????-??????????
With 5" VC and 280mm O.D. magnet, the overall proportion looks like a 12" woofer, but it's a 15", wow! And it seems too cheap to be true for the materials. It's about US$ 128.5 now.
It's said to be (authorized) RCF LF15N451, but that model in RCF's site is completely different: RCF - LF15N451
How interesting.

RCF inspired but not their design.
The magnet looks similar to one I've seen on a PRV woofer. It's just one of many knockoff Chinese products. I'm curious how they perform though. Lots of stuff for a quarter or fifth of typical pricing. I suspect the quality control is non existent. There is some comfort in knowing all your drivers will be nearly identical when you buy established premium name brands.
One example as seen on partsexpress is PRV's clone of the 18TBX100. They look identical at first glance, but if you look closely at the spider it's a little different and it's missing the calibrated silicon on top of the spider that the B&C's have. I bought four 18PS76's and each one measured identical in fs and qts. I doubt there's huge audible differences but my ocd tendencies appreciate high level consistency.
