For speaker wire on a z combo does it matter where the white and black wires connect? Positive and negative , I never hear any difference. Thanks!

No difference unless you're playing with multiple amps. If the two (or more) are out of phase, you'll get cancellations in sound waves.

It's always best to keep the polarity consistent, black is connected to the ground on the speaker plug as a general rule of thumb, so it's best if it goes to the negative side of the speaker.
I don't know if it damages the speaker over a long period of time, but if you were cranking at a decent volume for a couple of hours you might get excessive heat build up at the speaker coil.
I don't think the Output Transformer cares as long as it sees a place to transfer the load.
I have opened the speaker plug on a number of amps to verify the wiring, I sometimes solder the speaker tabs so I like to make sure I have the polarity correct.
I worry about impedance matching and all of those things and there is no reason to break the rules, black is negative and white is positive on a typical combo speaker harness. Let me know if that is incorrect.

Let me know if that is incorrect. Purpletele, I agree with your comment and the above comments ^^^. To add, one can test wring polarity using a Multimeter (Ohm meter), each reading should be near Zero ohms, if not, then you are measuring through the speaker coil and the leads are swapped within the plug/jack. (1. & 2. are individual measurements.) Combo - measure from Speaker cable Plug, 1. Tip (+) to White lead connector and, 2. Ring (-) to Black lead connector. Cab - Insert a speaker cable in Cab Jack and measure from unconnected Plug end, 1. Tip (+) to White lead connector and, 2. Ring (-) to Black lead connector. (pre-test verify your speaker cable has only continuity tip-to-tip and ring-to-ring, if not it is swapped, ouch) The assumption is White and Black cabling is utilized (Z speaker wiring this is true), but one may have other color wire in place, therefore Tip to (+) and Ring to (-).

While it's important to wire multiple speakers correctly or you get obvious phasing issues ( sounds bad ). I don't think it matters at all which wire white or black from your amp goes to the + or - speaker terminal. As long as you are consistent with it in multiple speaker set ups. I say this because the output to the speaker is AC and cycles between most positive and most negative 60 times a second .
