This resistance you speak of is actually IMPEDANCE measured as DC resistance. Typically it is a nominal number as it will vary through the frequency range. The signal to your speakers is amplified AC.
A little reading on the subject will help you understand, I suggest the NEETS series linked below.
Module 1 to help with DC basics then module 2 will help you with impedance.
Also tube amps generally like a flat impedance curve or graph.
