Best Capacitors for Crossovers

I am now in the tweaking stage of trying different caps in my crossovers for my DIY homemade 2 way. I presently have and will soon try a 5.6uf 800 vdc +/- 2% Jantzen Audio Silver Z-cap.

I see that Mundorf, V Cap get a lot of accolades, and the Dueland are quite pricey.

Does anyone have a favorite?

I am trying to cross over at about 4500HZ at 6db.

About 2-3 days of continuous play.

You may be better taking this thread over to DIYAudio where you can post images like schematics and measurements.

Best,

Please let me know the components you are using. What caps and resistors etc.  This will help me better tell you what to expect and break in based on my experience with these various parts and brands.

Nice! Well that tweeter matched with that particular cap will give a very detailed sound that will certainly start off hot sounding. The Jantzen silver cap is known to be very detailed and tipped up in the highs. Even after burn in that personality will prevail. 

I have had great luck matching ribbon tweeters with copper foil caps from the likes of Jupiter. I had that combo with Raal ribbon tweeters and it was wonderful. I think burn in will be closer to at least 100-150 hours to be honest.

grannyring,

Thanks for the info. I also wired the cap with the tweeters using .9999 silver cable. I know that when I had the Von Schwekert’s speakers as new they sounded pretty tight for about a month. I even ran one out of phase and moved the speakers together face to face for several weeks.

I am not too concerned at this time though. I know wire takes at least 200 hours to flesh out and what I am using is all new wiring, caps and speakers.

With my Pass Labs amp, I don’t want to play it continuously so it may take a month to fully develop. So, at that time I may experiment further with other caps.

More to discover
