Here are some reviews of some of them including the Eton. They are in German but Google Translate will give you the general idea. Be sure to click on the "Show Full Review" link at the bottom to see actual t/s measurements of the woofers as well as detailed ratings on a number of areas:

Thanks for digging these German reviews up.

The reviewers say this about the Etons (in rough translation):

"If there is a specialist for BMW speaker replacement, it is Eton... The mid-range makes a noble and high-end impression... One always has the sense that the speakers reproduce the music accurately and precisely... Conclusion: sophisticated manufacturing and sound."

Sounds right to me.
