I’m considering upgrading my speakers internal wiring

Already mentioned but still want to add my two cents....

From  real world experience, not just what I read or watch on youtube....

I would dive deep into this and learn all you can first then look at not just wire but also the resistors as those look like sand cast. Inductors as I found foil much more to my liking, capacitors, hard to tell what you have from pics of the crossover.

And wiring.

And solder.

And binding posts (or lack of, I prefer direct wiring to the crossover or if possible to the driver terminal and I always solder the driver wires)

Some components will not matter, those directly in the signal chain are far more likely be the ones to look into.

Some changes you might like but if you do the research and pick parts that fit your particular tastes you might save time and money on the upgrades.

If you have any issues with a particular aspect of how they sound you can focus on that and tune them to your liking, at least I hope there is room in the design to accomplish that.

The advice to contact the manf might prove the best course to follow so I would at least ask but it might not pan out, some might not like getting asked such questions, sensitive egos and all. I do not know nor have dealt with this designer so not pointing him out, just general thing to consider. I have had to deal with many stubborn "engineers" in my lifetime of modding things.

FAR more important, have fun:)

I agree with @stereo5 ​​@mapman @erik_squires 

OP, you asked for some thoughts. I wouldn't do it.

The best speaker designers on earth themselves are quite humble, constantly learning and revising things. So, Peter and his speaker are not set in stone. Peter himself may have a lot more to learn like other designers. So, you can go to town with the tinkering and not worry about "upsetting" Peter (good grief, facepalm). He got paid and they are your speakers now, i.e., you can do whatever you want with it.

A simple upgrade for many speakers could be to try slapping some no-rez sheets inside the cabinet, see what it does.

Consider joining groups like the ’high end loudspeaker crossover upgrading’ facebook group. You’ll find more detailed posts, schematics, pictures, etc and those nerds could help sort you out, if you got stuck or something (i.e. if this type of tinkering becomes your near-future venture). Such info and dudes are also scattered around in the diy audio forums.

Think of it as tube rolling, op amp rolling ,power cable rolling, speaker cable rolling, etc whatever....You are just ’rolling’ your internal crossover and wires now. Some ’rolling’ attempts could fail and you could always roll back to Peter, in such instances. Some rolling attempts could one up Peter’s design...that’s how it works.
