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.
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. |

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. |
