Sonus faber crossover

Postby Mamimili » Fri Nov 25, 2016 4:57 pm

I have a failed crossover on one of my EAII's.
Can i buy a single new crossover? In stock in Manila?
Or, would it just be easier to get it repaired? How would this affect sound when using an original and a repaired unit?
Sob.... ;(

If you have no choice but to repair your old xover, have the other pair "repaired" with the same parts as the broken xover. That way you can at least guarantee a minimal effect in sound.

I had upgraded the parts of a sonus faber speakers before, concertino and concerto. The crossover are encapsulated in a tar like material for resonance control. With the upgrade of the tweeter capacitors (mundorf silver oil and Hovland), it was a substantial improvement. For me, the sound of the Sonus was still there, it just got better. More open, less grain, more listenable at higher volume, etc. But of course you need to do it on both crossover if you want to repair yours and use the best parts that you can and you will be rewarded very well. :)

Where do you buy caps in Singapore? A shop or on-line?

There are two ways of removing that tar like substance, either by freezing it, then break it slowly or boil it until it melts. Try which will be more practical for you.

Interesting, i wondered if it was possible to peel it off in one piece and reuse!
Freezing sounds the easiest.
By boiling, do you mean immerse the entire crossover in boiling water? I assume that would mean replacing all components?

Do you use any similar goop after upgrading caps or just leave bare?

You can use those melting glue as a replacement or cable tie.
