Thorsten,

This is a popu;ar musconception, the series network CAN accomadate unequal impedances, I posted about this over at the Madisound board, see:
http://www.madisound.com/
and click on the Audio Discussion Forum

They have a seacrh engine, but even the archives scrolloff the board after a month, so the board is limited to two months of posts on a sliding basis.

Also, see:

See:

for simple design info. (Andy's chart and diagram).

and here's the re-post on different impedances:
BTW, it is not a requirement that each driver be identical in impedance, etc. For instance, if the tweeter were 4 ohm, and the woofer 8 ohm, you figure the inductor for an 8 ohm load, and the cap for a 4 ohm load. I know this seems counterintuitive, but the signal for the woofer really is passing through the inductor, and the signal for the tweeter really is passing through the cap. I have verified this via measurement, so I know it works OK. The proper shape and phase responses are maintained, and Zeta can still be adjusted, with regard for the proper load R.
