How important is a smooth impedance curve for speakers on (SE) tube amps?
I've heard it mentioned a couple of times recently. I'm in the process of looking for a DIY design to build and have found a couple with very smooth impedance where it was mentioned that it is good for tube amps.

Depends on the tube amp 🙂
Poor or nonlinear damping factor will need smooth impedance curves to sound "accurate"
Many non-feedback designs have a low damping factor and will work better with a more smooth impedance curve. Same with certain topology like ultralinear or pentodes. Triodes are more forgiving.

Good to know, thank you.
I won't dismiss designs that have some impedance swings since my amp has some feedback and is wired as a Triode.
One I was looking at jumps to 23 at about 60Hz and 26 at about 1.2K
