Kreg Posted January 21, 2019 Share Posted January 21, 2019 Hello everyone I am new to the forum and I have recently purchased a pair of Cornwall 0nes. I really like them. I am looking for advise for finding great capacitors for the Type B crossover. The reason I'm looking into a cap upgrade is this, I noticed that the original capacitors in my Cornwall's have been replaced with Sonicaps-Gen1. I'm interested to know if there are better caps for the Cornwall. I would really like to be able to try the original caps, as they were part of the speaker's original voicing. If any of you have any advise please share. Kreg. Quote Link to comment Share on other sites More sharing options...

Panelhead Posted January 23, 2019 Share Posted January 23, 2019 Sonicaps are fine. Someone has already upgraded the crossovers for you. BEC of Dean can give you tips in getting the most from the speakers. Quote Link to comment Share on other sites More sharing options...

No you don't. They are most certainly out of spec. Even when new would not have measured as good as those Sonicaps. 1 Quote Link to comment Share on other sites More sharing options...
Deang Posted January 23, 2019 Share Posted January 23, 2019 He doesn’t want the old caps. He wants capacitors that are similar in type to the originals. Quote Link to comment Share on other sites More sharing options...

Thank you to you all for your replying. How do you think the Arizona Blue cactus caps will work compared to the Jupiter and Jensen. The are reasonably priced and come in 4 and 2uf.

Deang Posted January 23, 2019 Share Posted January 23, 2019 I’m getting ready to start using them in my tweeter circuits. I didn’t mention the brand because I didn’t know they came in 4uF - and I didn’t want to complicate the response by suggesting using different types for different parts of the network. Where are you getting the 4uF? Thanks. I also have a pair of networks for a different loudspeaker that I’m going to use them in. Higher values would be beneficial.

I get that but those would be Mylars or motor start right? My understanding is those are not so good. Quote Link to comment Share on other sites More sharing options...
larryk Posted January 23, 2019 Share Posted January 23, 2019 I second the Jupiter caps. I have them in my type b crossovers. I realize that they are a more expensive option but they have a very natural tonal quality. I have not heard the sonicaps but the Jupiter’s were far superior to my original oil caps.

Deang Posted January 23, 2019 Share Posted January 23, 2019 Well, that's Dave's point -- ANY new capacitor should sound better than something over 40 years old and ready to leak all of the boards. Quote Link to comment Share on other sites More sharing options...

Hi Deang, you are not mistaken, there is no 4uf cap is made by Arizona. I would have to use two 2uf to make a 4uf. Do you think the Arizona caps would work well in both positions of the Type B cross over? or should I use something different? I noticed that Jupiter doesn't make a 2uf or a 4uf cap. It seems not many capacitor company make those values. Thanks, Greg Quote Link to comment Share on other sites More sharing options...
Deang Posted January 23, 2019 Share Posted January 23, 2019 Yes. It can be problematic. You should do 3.9uF Jupiter VT at the primary, and Arizona Blue 2uF for the tweeter section. Quote Link to comment Share on other sites More sharing options...

Now I have have a few more questions before I place my order. - What combo do you think would be the best (A combo) 3.9uF Jupiter VT at the primary, Arizona Blue 2uF for the tweeter section would be better than (B combo) 3.9uF Jupiter VT at the primary, and 2uF Jupiter VT at the tweeter section. Would you explain why one combo is better than the other please. - Where would you suggest as the best place to purchase the caps? I usually order parts from Parts connection as I live in Canada, but for some reason they don't carry a 3.9uf Jupiter VT. I looked at Sonic Craft and they have all the Jupiter VT caps as well as all the Arizona Blue caps. - Do you think going from the Sonicaps to the Jupiter/Arizona is a good up grade?

Schu Posted January 24, 2019 Share Posted January 24, 2019 "Best" is a very subjective idea... you wont know until you try it. Quote Link to comment Share on other sites More sharing options...

I would like to now what the experienced klipsch forum members think are the best caps for the Cornwall's. I hope this will help me get things right and save me money by avoiding a lot of trial and error. Saving money and great sound is important to me.

Thanks, Greg As one would expect, there are just different opinions about this. It's an age old debate and I think most of us are just tired of it. The Sonicap is a good part, there is absolutely nothing wrong with it. Most seem to be more than satisfied with the results, but ... Quote Link to comment Share on other sites More sharing options...
