Capacitor

You sure that's the correct value?

200 percent sure its auydn Q6 cap 100uf 600 vdc

I recently upgraded my entire crossover with huge, huge improvement! https://forum.audiogon.com/discussions/millercarbon-s-mega-moab-mod-meander
The two smaller value caps I was able to do with the very highly regarded Jantzen Alumen Zcaps, with a Duelund JDM Silver .01uF bypass cap. There was one cap of 125uF which would have been very expensive to do that way. So instead I used one 100uF and one 22uF Jantzen Premium Elko, with a 3.2uF Alumen Z bypass cap. (Voltage btw is not a factor, that is for use in a tube amp or other applications not in a crossover that will never see even 100V.)   

Pictures of actual parts used are on my system page here https://systems.audiogon.com/systems/8367


Alumen Z are not cheap, but compared to Duelund they are! And they are very highly rated. http://www.humblehomemadehifi.com/Cap.html

Thank you very much, Rick!

If you go this way please be sure to pay attention to your space and the dimensions of the upgrade parts as the physical size of quality parts is huge compared to lesser quality parts!

Also everyone focuses for some reason on caps, but do not underestimate the contribution of inductors and resistors. Read my thread, I did all of that and more, and it is not just a huge improvement it is like better than I ever heard before.
