Magfan:
In spite of being an engineer by original trade, I can't say that spend quite as much time analyzing empirical data associated with gear as I should. It's often confusing to the average, prospective client, but I do believe that this approach is very valuable assuming the testing is performed properly. Cudos...
That said, I was able to find an impedance graph in "Australian HIFI" magazine of all places. (The full written test can be found on the Elac Site.)
A PDF of the frequency response and impedance graphs can be found at:

Keep in mind that the test is for the Elac FS249. This is essentially the higher cost audiophile version of the 208 referenced by Mr Elusive but should behave similarly given the same basic design. The curves do indicate a dip in the 20-40Hz range and a significant dip again in the 60 - 200Hz range. I believe this would support my observed demanding nature of the speakers for high quality amplification, in spite of the fact that the sensitivity rating is fairly "friendly".
Thanks for the technical prospective. It's a reminder that we should consider more than one prospective on how we evaluate products in our business. BTW: My experience with tube gear with the Elacs supports your assumptions as well. I have not had good luck driving Elacs with the several lines that I carry.
Thanks
