from my experience, bang for the buck, I would go for Clarity CSA. If those are too high, I personally would stick with Solen PPE. I've listened to a bunch of budget friendly caps, they are more neutral than most and don't do any nasties that others do in lower treble region.
What might a good to great 20uF film/foil capacitor for a woofer.
I’m building Type B-2 crossover for Klipsch Cornwall’s. I’ve done a couple of pairs so far and they sound great. So much better than the stock B crossovers. I would like to build even better type B-2’s using different caps for the lower frequencies. I’ve come across some B-2 crossovers online for sale yet they use low-grade bobbin Inductor coils. I have been using 2.50mH 16 ga EQ Perfect Lay Hollow Air inductor coils by Erse, great coils, lately I haven’t been able to get them. The longest backorder time ever, several months now. I switched to Jantzen Audio’s Litz Wire Wax coils, offering 0,15 Ω | 3% | 15 awg. I have been using Jantzens Supreme Z 3uf, and 4uf capacitors and will continue using them. I like them better than Mundorfs Supreme S/O oil caps as good as they are. Too spendy for what you get compared to the Jantzen Supreme Z caps. I’ve been using Erse’s 20uf 400v caps. I would like to try something else (20uF caps) for the lower frequency. Any suggestions on good 20-22uF caps that would improve the lower frequencies and not cost a whole bunch? Thank you.

Not certain which inductors you still need, but: I have a pair of these, somewhere around here: https://www.mundorf.com/audio/en/shop//MCoil+CFC14+AirCore/?card=5656 If you're still in your x-over's design stage: I wouldn't think a <10% uptick, from what you desire/used prior, too hard to work around. |

I am starting to use Jantzen Audio’s Litz Wire Wax coils, crossovers are 95% done, I just have to decide on the bass cap. I was looking at Jentzan’s Supremum Z 20uF but they’re expensive $$$ for a pair of them compared to the Erse 400v and other caps I have considered. I don’t want to pay for a boutique priced cap when I am looking only to improve the bass and waste money (losing/wasting) the med and top end frequencies? I have used Axon in a couple tube amps with great results but should i consider them for a bass woofer? I will look into the VH Audio ODAM, never heard about them before. I was looking at Clarity caps when I ordered the Jantzen Litz Wire Wax coils. I should have grabbed a pair to try out because I already paid for shipping. It wouldn’t have added any to the shipping cost being they don’t weigh too much. I appreciate all the info/ideas. I’ve also been using some remarkable 1939 NOS unused before Western Electric No. 10 Tinsel wire/cable switching out all the (1976) Cornwall’s driver wiring shortly after installing and listening to the upgraded B-2 crossovers. That made a remarkable improvement in sound quality. Also, I'm now using 1930-40 Western Electric cloth over silk over enamel 18 ga. solid copper wiring for the crossover wiring as well. Very nice sounding wire. |
Tough question, have not tried it but my guess is why don’t you check Jantzen Standard Z cap, Clarity Cap ESA, Audyn cap Plus. Maybe more than enough for bass region but can handle extreme pulse, are low loss, and not so expensive for the required value. Only the Jantzen comes in 400v, the other two in 630v but their values are in 22mf or 18 mf not 20mf. You can check Humble Homemade HFi and HFi Collective for more info.
