the opposition to the flow of alternating current by the capacitance or inductance of an electrical circuit; the imaginary part of the impedance Z, Z = R + iX, where R is the resistance, i = √–1, and X is the reactance. It is expressed in ohms
Compare resistance (sense 3)
2.
the opposition to the flow of an acoustic or mechanical vibration, usually due to inertia or stiffness. It is the magnitude of the imaginary part of the acoustic or mechanical impedance

Reactance is a form of opposition that electronic components exhibit to the passage of alternating current because of capacitance or inductance.
The speaker's reactance does not play a part in shaping the overall tone, since the interaction between thespeaker and the tube amplifier is non-existent.
You can determine the leakage reactance of each winding on the basis that the same amount of equivalent leakage flux linkseach winding.
