custom Crossover building service??

I agree with Elizabeth on this one, with most dynamic type speakers its best just to leave them alone. Planer magnetic's/ribbon's and electrostat's are a different story but that is not the case here! Ask Albertporter about his old Snell speaker's and the "improvements" he tried to make.

In this case you're just playing with the chance.
If you just listen to speaker and like it, but after looking inside seing poor wires and poor parts you aim to upgrade, than probably you'll loose. Speaker CAN sound great no matter what parts are used depending on the design. It's essensial, that such speaker will sound best with it's original crossover parts no-matter how bad they are.
If you don't like how your speaker sounds or if it's not too expencive, than you probably loose nothing and you can try.
Upgrading crossover is much easier than upgrading components - so you can do it yourself by replacing electrolytic caps with large film ones from Solen, Aeion or Unlytic. Re-wire your speaker with solid core wires from Belden instead of stock stranded ones and many more depending on the brand of the speaker.
You can ask an advice from Michael Percy at www.percyaudio.com what parts are the best(you can mention budget as well) to upgrade the speaker that you don't like anymore.
The other way is to sell the speaker you don't like and buy the one you will definitely like. IMHO if I spot such thing as upgraded crossover I'd rather avoid that purchase.

thanks for the input people. Got a question though.

As long as I use the SAME VALUES for everything then how could the results be negative? I would just be using better quality components. I don't want them redesigned.

I re-did my Magnepan Xovers with GREAT success. They were easy and Magnepan faxed me a schematic. I sent Athena an email asking for a schematic and so far NO reply.

the stock crossovers look pretty weak. they are about 3 inches square and each contain 2 inductors, 2 caps, and 2 resistors!! Tiniest crossover parts I've ever seen.

I DO like the sound of these speakers, as did Stereophile. I just figured they would sound even better with quality Xovers, just as my Maggies Do.

thanks again!
