The interaction between a tube amp and speaker is more complicated.
As the output impedance of the amp goes up, the frequency response of the amp/speaker system looks more like the impedance curve of the speaker.
Sticking to high impedance speakers with small impedance variations helps. Sometimes the match is good, sometimes bad, and of course, getting good treble out of a tube amp may be a little harder.
