Thanks X3 Oiler.

Here is a link to Sonicelectronix here in the states. They have both the sps-400 and sps-410 in stock. Interstingly enough the one person that reviewed the sps-410 stated they sounded better than the Hertz ones he just replaced.

If it is only .5mm in my professional opinion I agree that shouldnt make a difference. One of the nice things about the newer version is that the tweeter is adjustable in direction.
2013 S4 Loaded (and NO RFT's) Awesome is an understatement
