What is SPL high and low impedance VituixCAD

I am trying to start on learning to build speakers and have chosen VituixCAD.
It ask me to fill out the drivers high and low impedance, what does that mean?

Each scale division is 0.5 ohm, so it is 6.5 ohms.
Many thanks!!
I do know that i may not show it, but your help do mean a lot to me, I am so grateful, thanks for all your help. I also know that I may seem like I don't read half of it, but I try, it's just that English is self thought and electronic is a new wonderful universe where I do know nearly nothing!

What's your native language? English takes kids here years to learn, but we grow up with it.
Can you find electronics books in your native language? Here's a good one in English.
I am so lucky that I do understand English speak fairly good but I takes some more to read it. And my grammar is so bad I wonder how anyone do understand what I am writing.
There are book in Danish but to be fair, I do not think you can find much newer then 1980 and since YouTube, Fora, Datasheets and so on is in English, do I try to learn it all in English.
Thanks for the link! I do often let the computer read out loud if I want to learn from longer texts!
