For 68 µF?
In our big 2-way MTM there are a few 240 µF caps.
BTW thw French factory thaat OEMs the Solens also makes a bunch of other brands of caps.
Cheap is when i bought a bunch of clearance 1oµF polys. $2 USD each. I only boiught 20 i should have gotten more.
4 of thoise are going to replace the caps in an old set of Isophon Combis i have.

Gifted to me. But a local artist (https://www.mileslowry.ca/) that was a Mac customer has a set hanging from his ceiling. Driven by a smallish NAD they sounded enjoyable.
I am looking forwatrd to see what they sound like in my system. And am hoping to eventually use them as part payment for one of his sculptures.

Any ideas for the smaller 2uF capacitor? The one in the crossover is so small and the ones that I find are so big lol
Potentially, smaller capacitors can be better, but in this case it’s not likely to make a difference.
I swapped out the main caps. There isn't really much room to change the radial for an axial one so I left it there for now. They all just fit on the board right now. I only got one speaker swapped so far, will have to do the other later tonight. One thing I came across that I didn't expect was everything was glued to the board so I had to buy a heat gun to get the stock caps off.
Before doing the other speaker, I would compare the re-capped loudspeaker with it to gauge the extent of the audible improvement.
Do tell us what your listening reveals.
Another thread on the subject of Danny-boy’s visitation to this design, which he quite likes - including the overall topology of the XO - just his usual comments about cheesy parts and ferrous materials in the signal path (don’t forget the sand cast resisters). For a bit of synchronicity, I watched the YT video earlier today; but as is often the case he doesn’t show the extent of the finished build with the non-dairy components.
IINM, he doesn’t provide PC boards or his upgraded circuit designs, so the fun decision is how much to cannibalize the existing, or to PTP on hardboard.

Surprised to see the same value Jantzen for less.

Would have to keep the XO external if I wanted to fit that 68uF cap in there. It's already a pretty snug fit with all the other ones
The most significant issue I see in the stock crossover is the steel core inductor in series with the woofer - the top inductor in post #26. Changing that out for a heavy gauge air core inductor probably will make the most significant improvement to sound quality. Such an inductor will not fit on the PCB. I would add extension leads to it to allow it to be mounted inside the cabinet somewhere near the crossover. Keep it perpendicular to whatever inductor(s) happen to be closest to it. Just don't mount it with anything ferromagnetic. Maybe hot melt and a nylon strap of some kind.
