You were talking 100-250 uf That is huge , what kind of speakers are these ?
most speakers are under 10 uf for the Bass woofer. You can vary the tolerances up to around 3% of the total before it starts effecting the Xover point a decent 1% of the total in a decent poly cap will smooth it out abit , and a good quality
awg 12 Jantzen inductor open core would do it justice , I don’t use junky
cheap sledge hammer type a magnet 🧲 with wire wrapped around it .
Jantzen are my favorite and great quality value ratio if you want a quality inductor
speaker you are keeping . I rebuilt a nice Dynaudio speaker last year ,that I will be selling in the fall it now is called the model 30:$8k and the Xover use Mundorf Evo caps decent ,but Mundorfs Supreme are their much better line. In parts maybe $400 I spent $1600 just in parts ,a solid 15-20% improvement in fidelity ,
pits the 🧠 or ❤️ of the speaker everythung hood or bad goes through there
thsts why I always use top solder Cardas or Mundorf, and WBT connectors
stock connectors on 90% are bright gold over brass , WBT Evo next gen $40 each
at VH Audio I spent $250: on the WBT classic no short. Cuts ,Everything counts .!!
