Just FYI, I have done a simulation of the Focal Profile 918 with the ScanSpeak Illuminator D3004/6040-00 Beryllium tweeter. I used measured data I had from my Focals plus ScanSpeak's spec sheet for the final design.

The blog entry is here.

In addition to other benefits of Be tweeters, the Illuminator just has a much better motor giving it a much smoother response. You can compare the original Al/Mg inverted dome with the Illuminator here:

I really wish I had thought about this before I parted my Focal's out. << sigh >>

The crossover is so ridiculously simple it is painful. Damn.
