I second dekay's advice for a good, inexpensive, diy amp. Don;t fret too much over the impedance, tubes have high output impedance (hence the output trannies) and love high impedance loads. Also remember, if you're measuring the Fertins with a conventional multimetre, what you get is the resistance rating Re (dc) -- not impedance Z(ac).
Again, as dk suggests, the baffle will be an important contribution to the sound. Why don't you try out PHY's "panneau plan" -- or Supravox's. They work very well.
As I mentioned in an earlier post, the field coil allows you to play with the drivers' characteristics to suit your tastes. More than most of us with fixed magnets can do!
