How important is it to use non-inductive resistors in a crossover. I can't find exact values(10%). Are wirewound's not acceptable?
And is non-inductive a wire wound with a counter-rotating layer inside?

I have built good sounding speakers with wirewounds in the past and beleave resistor inductance is a lesser issue if it is one at all.

Just use the standard white ceramic resistors, they are not more inductive than others below 20Khz anyway!!
Less important than cap or coil quality
Still audible? Maybe. Caps and coils definitely are in my experience. You're right that a non inductive wirewound is typically a counter-rotating coil.
Whether it's worth the dollars to go with fancies is another question, that only you and your own ears and wallet can answer.
Most of the time I use the white sandcasts.

Caps do make very audible difference, even if they have the exactly same capacitance, ESR, ESL. There are other parameters that influence the sound.
For air coils, how would they make difference if the inductance and DCR are exactly the same, or the DCR is padded with resistance to be the same?

Inductances of standard resistors and capacitors, and capacitances on standard inductors, are by far low enough to not have any effect below 20Khz. Most standard components have at least 200khz bandwidth.
You can safely forget about parasitic inductances and capacitances on speaker crossovers.
Be careful with placebo effect too 😉
