Duelund cast Pio Hybrid Copper/Silver or Rs series with Silver Bypass PIO

You made a good decision sticking with the heavy gauge solid core  wound over foil. You will love the results.  What are you using for internal wire. Looks like Duelund copper stranded? Thoughts of placing the crossover outboard? Very good for Sonics. 

 Nice  looking speakers. Look to have great build quality.  

The New Duelund Tinned Copper,paper in oil  .1uf bypass caps are Excellent 
The New Tinned Copper which their new Jam caps have which I have in my preamp are truly excellent they have a aluminum case ,not quite as good as the top paper case.  The Tinned  Copper bypass cap I just got  .my brother and his friend say these little caps truly add depth,as well as air to loudspeakers.
They also have a Silver paper in oil , a little better detail ,then the Copper bypass 
But not as much body. And at 600volt  can be used anywhere.

Hi,
I have Altec 604E speakers with Werner Jagusch crossover. I bypassed high frequency driver's part of "original" WJ crossover vintage capacitor with Duelund Tinned Copper Foil & Wax/Oil BYPASS capacitor. Sound improved a lot. It sounds like new, much more expensive speakers!
I'm thinking about buying Duelund RS capacitor.
What do you think, will Duelund RS capacitor bypassed by Duelund Tinned Copper Foil & Wax/Oil BYPASS capacitor significantly outperform "original" WJ crossover vintage capacitor bypassed by the same Duelund Tinned Copper Foil & Wax/Oil BYPASS.
Regards,Alex.

Yes it will. Jupiter copper foil will be even better with that wonderful Duelund bypass cap.
