Rebuilding ESS AMT series crossover.

I've read enough here to understand that my crossover network is past due for maintenance. They are powered by a B&K Reference 200.2, and the preamp is an Onkyo SR701. I've already replaced the diaphragms and woofer (impedance matched). The speakers are an early release with there only being a single 10" woofer, and it is ported. I am hoping to find a schematic and recommendations for the C & L components. I appreciate any help since I've just discovered this resource. Thank you, Bud

Budkoss, I would suggest substituting crossover parts with wiring installed with alligator clips.I did this when modifying/building two sets of speakers.It is amazing the difference changing out a single component can make.I learned quite a bit about the integration of the drivers and the effect of different capacitors.If you must choose one over another,choose the one that allows best integration.Bypasses and wiring can augment or change a weakness elsewhere.

I am currently using a ESS Heil tweeter in a 3 way. I just upgraded the capacitors in the tweeter leg to Jantzen superior series Z capacitors and now I have the most fantastic tweeter I have ever heard. Although I have had this tweeter for at least 20 yrs, it did not take on this incredible sound until I added the new capacitors.

Have used the Jantzen cross-coil inductors and really like them.

I appreciate your feedback and recommendation. I will begin looking for them now. Any thoughts on crossover for the woofer. I'm thinking mine were designed for 1,000 Hz, and I've read that 750 to 800 sounds better in the bass. Any thoughts on this?
