604e Crossover Advice

I just won a pair of these speakers on eBay, but they don't have the crossovers. Can anyone suggest which crossover I need to look for?

Thanks!

Bob,

Look for either an Original Altec N1500 or the "Mastering Lab" crossovers for your 604E's. You can build a copy of the Mastering Lab it is much better than the N1500 mastering lab crossover

Thank you so much, I really appreciate the information!

Bob

Thanks very much Jeff. To be honest with you, I'm not very good at building anything and would prefer to purchase the crossover that I need. Would you know anybody that, for a fee, can build these for me?

Bob,
You might also spend a bit of time reviewing my home page at http://home.earthlink.net/~jmarkwart/
for a look at possible 604 crossovers that may be a bit easier to build than a Mastering Lab clone.
