Mission 782se filter schematics

[SwiftFlic]

Hi all, I am looking to upgrade my 782's (+78c&780) to 782se. This should be just an improved filter. Does anyone own a pair of these or know how to get the schematics?

If not possible I am going to design a filter upgrade myself. The current one is really basic. Any good sites on how to design a high end speaker xover?

Thanks a lot!

You should be able to read the values off the components in your crossover, combine with the above and you have your schematic.

Might consider simply upgrading the existing crossover components rather than designing a new one from scratch. Doing a scratch build crossover requires test equipment, software, combined with the knowledge and skill to use them.
