Hi @grannyring
Two questions. Why did Danny decide on using the JFX capacitors? Curious about his reasoning here.
I don’t know that it was necessarily "spec’d for a particular reason" and against something else, for a particular reason. An obvious thing would be cost. I think he certainly recommends using better stuff on tweeters, and that’s a common upgrade option for any of his kits, upgrades he designs, etc... Sonicaps. What is here is what he put together, and he put in the higher cost Sonicaps for the tweeter without me asking for them - but I would have done them anyway. I have seen where they and others discuss caps a fair amount, and they play with them. Many will use foil inductors, for instance. I believe the inductors pictured here are US made and from US Coils. If I’m not mistaken, I think they are former guys from ERSE? Whatever the case, this is what we went with and I didn’t push the issue on using foil inductors, Sonicaps everywhere, etc. I wanted to keep some sort of lid on this as the investment can get out of hand pretty quickly. If he thought this setup were inappropriate for the speaker, he wouldn’t have put the package together. We did discuss the bypass caps. Those are not pictured here, for a reason. Danny was out of Miflex .1 caps. JB caps were sent, and I may clip those in and see how everything is. The bypass cap stuff is likely something I will play with... clipping different caps in to see if I like something better. That’s why they aren’t soldered in.
Here is some commentary one of his guys had about this parts topic. He has a pair of the NX-Studio 2 way speakers and has been playing. It’s a sceenshot from his spot elsewhere. If AG doesn’t like it, they can delete it.
Lastly, why did you blackout the values of the capacitors? Not seen that done before on all the crossover pics I have viewed over the decades.
Isn’t it interesting that Wilson Audio has their crossovers potted so that nobody can see the parts, even if you own the speaker? They also will not share a schematic of the crossover, even if you own the speaker. I also know, first hand, that they won’t bother responding to a simple question about the kind of wire used in the speaker. For that matter, I believe the wire is by Transparent, but it’s moot at this point anyway, as I’m "hard wiring" the crossover, to a degree.
With that being said, I assume you aren’t familiar with what Danny does for this stuff, as what I did is quite common among those who appreciate the service Danny offers, for FREE. You’ll find pics in Danny’s forum will be the same. I’ll explain how this works... I spent ~$400 to ship a crate with the Duette in it to and from GR-Research in Texas. Danny makes it well known...in his videos, in commentary in his forum, by calling him, etc. that he will measure and design a crossover, for FREE. EL FREEBO. In fact, he encourages people to send him speakers. He’ll share the measurements, what he thinks is going on, and what he thinks should be done. He will design a new crossover for it, and take measurements. The images you see in this thread are from that process. If you want the crossover schematic, you just buy the parts from him. He may make a video about it, maybe not. Obviously, it’s content he can use to show people what he does, it helps the person who needs help. Parts have to get bought anyway, so Danny makes a few dollars selling the parts. Even so, there is no commitment to move forward on the crossover / buying parts. If you don’t want to have a crossover made for it because of issues / cost / the sky is blue, not a problem. He’ll pack your speaker back up and you’ll pay for shipping back to you. Oh, and you don’t get jammed on shipping - he plays it straight. Sounds like a fair deal to me. In my experience, he’s been an absolute pleasure to work with, and has done everything he said he was going to do.
So, that’s why the values are blacked out. I think it would be unfair to him if they weren’t, and I know that many other people who’ve done business with Danny feel the same way. If someone wants the crossover, you just call and pay the man. If another Wilson Duette owner wants to do this crossover, you don’t have to ship Danny a speaker - I’ve absorbed that expense for you - you’re welcome; however, you do technically owe me a Chic-fil-A sandwich, with cheese.
I like Mills MRA for low cost resistors.They are low noise and even handed. Yes, the ends of the Path Audio are magnetic, but they sound wonderful. Very natural and unforced.
Thank you for sharing that. Maybe I’ll try some one day. That’s part of the fun with this stuff...
