Gammastrep, your speakers are fundamentally different from box speakers as you know. The impedance curve is the result of 2 factors, neither of which has anything to do with resonance.
The result is that the 'conventional wisdom' about using a transistor amp to make the speaker sing is wildly inaccurate.

Your speakers are a Power Paradigm technology, so voltage-source power amps like big transistor amps are all going to have similar issues- too bright in the highs and not nearly enough bass. If you think about it, lets try the example of a 600 watt transistor amp. Into the bass, which is over 30 ohms in some areas, that amp will only make about 150 watts. IOW, any 200-watt tube amp will be able to keep up with it, as a tube amplifier will be able to deliver substantial power into an impedance like that. Any time you mix Voltage and Power paradigm technologies, you will get a tonal anomaly, in this case too much highs and not enough bass.
The bottom line is that you need to seek a tube amplifier if you wish to get the most out of this speaker. As you have noted, that tube amp should be capable of some power. IME you will need about 200 watts per channel to get things happening.
