Here are the drivers all basic Jamo speakers use (you'll probably recognise some of the faceplates, I can see the tweeter of the 606), note the fact that they are cheaper than even drivers made in India. I replaced a pair of blown Jamo drivers with those made by Peerless, and the latter sounded much cleaner and more precise than the originals.

Since they are factory buyouts, the stocks won't last so depending on when you click the link, there may be no results.
I have no idea what Jamo speaker model series uses these drivers. But I know that the R900 Reference Series, the C80 Series, the C60 Series, the C400 Series, the D7 Series, the S606 (S600 Studio Series), the S500 and S400 do not use these drivers.
These drivers must be something all together different. Maybe these drivers are used for their low end S700 Series and the D6 Series, only????
But those drivers are not the drivers Jamo uses for all their basic speakers. Even the tweeters are not what Jamo uses for the R900 Reference Series, the C80 Series, the C60 Series, the C400 Series, the D7 Series, the S606 (S600 Studio Series). The tweeters in your link are completely different. Not even close.
