Building crossovers

Marchand Electronics can probably help

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.

Thanks for all help Gents!

Give Danny Richie at GR Research a call or email. He had had at least one Magnepan model sent to him for evaluation, and he posted a YouTube video in which he discusses and demonstrates what he discovered. As he regularly does with loudspeakers sent to him by customers, he designed a new crossover for that Maggie.

Ah, here it is:

      Don't be dismayed, should your new parts sound less than ideal, upon first listen.

      The better the dielectrics used in construction, the longer the capacitors will take to sound their best.

                                                              ie:

        Also: the better caps will (usually) have their outer foil lead marked, to help with optimum orientation, in specific applications.

Would anyone be interested in building me a new upgraded crossover.
