I recently picked up a studio CC690.
when i started playing it, i noticed an annoying sound like the highs are echoing or vibrating,especially at louder volumes, where my dali is doesnt have this issue
its hard to explain, no amp issues or stupid sound fields, plug and play with my other centre doesnt have this issue.
it appears to be coming from the mid speaker below the tweeter.
I have pulled the cross over out for the tweeter / mid and found that it has 4 caps.
1. largest 5.65uf 250v - read 5.6 uf
2. bennic bipolar 100wv 10uf - read 11.24
3. bennic bipolar 100wv 33mfd - read 38.03uf
4. bennic bipolar 100wv 33mfd - read 37.53uf
They dont show any +- values.
3 and 4 seem high.
would these cause sound issues?
i have tried replacing the tweeter/mid with the same outcome thats what makes me feel its the cross over.
any thoughts on this? how much would a new cross over cost from paradigm?
what caps could i use to replace these with ?
thanks in advance

Bipolar (non polarised) caps have wide tolerance, typically 20% and so those 33uF's fall within that.
Bipolar type do not have - and + markings as they can be fitted either way around.

Well caps can fail or deteriorate in other ways besides the value changing. E.S.R. is one of the more important figures. If you have doubts then replacement is the simplest and cheapest option.

not sure why this speaker sounds so horrible for.
i have changed the tweeter mid section and it didnt help.
You probably have to look elsewhere than the crossover... and as with all these issues it is difficult without actually hearing what the problem is.
We can move this to Multiway if you think it would help 🙂

I believe i worked out the issue, i think i have two stuffed mid drivers, the spare off the shelf is bad, distorting when direct signal to it.
thanks for the help
