Defining nominal impedance


A speaker says it is 4, 6, 8 ohms nominal impedance. I'm trying to understand the word nominal in this context.

Wikipedia defines nominal impedance as the lowest value after resonance.

Q1: What is reasonance?

Q2: My amp has both an 8-ohm post and a 4-ohm post. For a 6 ohm speaker, is it better to go with the 4-ohm or 8-ohm post? Or will it depend on the amp and so I should experiment with both?

Jim always experiment with both taps one will certainly sound better to your ears.
