Paul Carmody's website shows that the tweeter in the Classix II has reverse polarity; I recall the original Parts Express product page showed normal polarity, which would be wrong. It should have been fixed by now, but it's worth checking.
Resistors are cheap, even in Oz, so if you want to use more expensive parts it won't cost much more.

I did notice that the 8 ohm version of the Peerless tweeter needed to be inverted. But in my modeling with the 4 ohm version, normal polarity seems to produce the best response.
Whether the tweeter is 4 or 8 ohms doesn’t matter for polarity, as far asI know. I would ignore the model and build the crossover exactly as specified, or it won’t sound right. I reversed polarity by accident and ineptitude of one of my tweeters when building my Classic and it sounded off.

It's not really my advice - thank Paul Carmody, the designer.
I found the Classix II really good with my 60s and 70s rock albums, many of which are a bit worn and weren't very well recorded or mixed. They're alos non-fatiguing and I could listen to them for hours.
Good luck with your build
