I’m considering upgrading my speakers internal wiring

I replaced the original wire with 18 ga Neotech teflon wire. 

I’ve always questioned the validity of spending tens of thousands on cable interconnects for components, and I have asked this forum more or less the question you pose: if interconnect cable is so important, why aren’t the amps, preamps, and especially speakers similarly wired point to point? It’s meant not as a snark, but a straightforward question. I have never gotten not only a good answer, I have never gotten any answer. At all.

For my Altec 604Cs, I ditched the crossover that they came with, bought a pair of Mastering Lab crossovers that were designed for the 604Cs, and had someone replace all the capacitors with audio grade Jensen foil capacitors.

At a minimum, if applicable, I would do away with any crimp connections that could instead be soldered and replace the binding posts with low-mass pure copper. There is no way those mods could have negative consequences.

If you change the wiring using UPOCC with Teflon, or cotton, dielectric and stick with the same gauge as OEM, how could anything negative come of that?

I think where people may have had negative results would be by changing the wire gauge in the high frequency paths.

Maybe that’s because the typical "you need to invest (sic) at least $1,000 in your USB and Ethernet cables" folks don’t know how their gear is built or what’s in it, and have zero interest in finding out, just like a person who believes the earth is flat has no interest in travelling to the edge of it: If, heaven forbid, there were no edge there, they’d have to renounce their belief; and if there was in fact an edge, they might fall off, and that’s dangerous. So, all in all, disincentives all around to go find out.

I’d ask Peter if he were making this speaker for a higher price point what caps & wires would he use?  Hats a nice Jon confrontational way of getting the builders opinion. 
Consider Master Built cables for your rebuild. My Von Schweikert’s use them internally. For sure will take away a potential weak link.Though at their price point you’ll for sure want to upgrade Caps too.
