I've updated the site with the raw EX-6.5 drivers since I've had so many request for them outside of the Kepler kit.
I spent a lot of time getting accurate measurements. I've measured these in a number of enclosures and the T/S parameters work perfectly to predict the low frequency response. A bonus of the small neo motor is that it takes up very little enclosure volume.
Let me know if you see any errors in the documentation. It is brand spanking new although the measurements have been gathered over the last year.

Quick comparison with the ever popular RS-180. Both are the same form-factor, cone area is about the same. I had them both mounted and ran in free-air and there is no comparison in output. The x-max figures may not look far off but the usable excursion difference is huge.
