DCM QED's Crossover Question

[Dr. Morbius]

I have a set of Mint numbers matching QED's, don't use them anymore. Would Barter town be a good place to list ?

That's the only place that AudioKarma allows. Also, Cragi's List and ebay.

I have the QED's with the nut on the bottom, is the crossover close to the bottom for easy access? I really would like to re do these..... Thanks Al

I know this is an old thread but does anyone have the schematic for the DCM QED crossover ?

 

[AlTinkster92]

Does anyone here know if the DCM QED speakers used electrolytic caps in the crossovers?

And does anyone know the best way to access the crossover?

Maybe someone has some photos of the crossover or schematics.

Please post them if you have them

Any info is helpful
Thanks

Here ya go, they are near the top on mine, has the bolt running thru from bottom to top. Mine are going out for repair. AL

Note: answering old question.

I have not seen any schematic for the qed. However, the crossover is very similar to the tf700 and tf1000 after you strip out the rlc network for the mids that those models have. Component values differ too of course. Also those models have 4 stage delay lines while the qed's is 3 stage. See this thread for a tf1000 schematic.
