I looked at an image of the crossover board , just one resistor and 3 caps , so replace the resistor with mills or path audio since there is only 1, I used Clarity Purity caps when I upgraded my Thiel 2.7 crossovers . Size , Size and Size , your options can be limited . Also replace the fuse with a ceramic one .

Yep, as said above use the same values and quality components. I like path resistors. hook the ground wire to your black terminal. I used Mundorf in my crossover and it got expensive. but with only one cap go for a good one, silver, gold oil. I’d probably leave the fuse out (just replace with straight wire) has it ever blown? I think a lot of people take the fuse out of their Magnapans but I’ve never owned a pair so I’m not sure. And I’d rewire. I used Duelund tinned copper cotton with excellent results. Jerry Edit to add: since you only have one capacitor, it probably feeds the bass. but if it does feed the mids or highs, add a duelund bypass cap, .1mF in paralle. It will cost $50 to $100 per channel. If it is in the bass feed, then don't bother. |
I built new crossovers for my speakers a couple of weeks ago. I used hookup wire from DH Labs. They have a nice variety. I used 18 gauge on the crossover components and 14 gauge to the new binding posts. I got the amount of Cardas eutectic solder I needed from Ebay. I'm very happy with the results. 3 caps and a resistor shouldn't be too hard to make. It wasn't easy but worth the effort. And a nice sense of accomplishment. There are YouTube videos you can reference. |
Marchand Electronics can probably help https://www.marchandelec.com/oem.html You might be tempted to get one of their tube electronic crossover that can potentially upgrade pretty-much any speaker. The beauty is that it's fully adjustable and you can set-up any allocations to your taste. These guys can also recommend an array of useful tools to measure all necessary settings. |
