Duelund Capacitors??

I have the Duelund caps installed in the tweeter high pass xovers of my speakers. I did not do lots of analysis or comparison, but Tony Gee has done an enormous amount. Look at his web page, humblehomemadehifi.com under the 'cap test' heading. He ultimately preferred the copper VSFs over dozens of others he's tested.

One other thing to note, and this is directly from Tony - to get the 'sound' of a capacitor, you only need 10-20% of the total value to be the 'good' cap. Example - you need a 5 uF cap for a HPF. Use a 4.5 uF Clarity Cap and a 0.5 uF VSF copper, and it's almost identical to the sound of a 5 uF VSF, and you've spent significantly less.

Happy listening.

For output coupling, should the 2 caps as above be used in series or parallel?

Thanks.

Steven, the bypass high-quality cap is connected in paralell with the larger, less expensive cap.
Their values add. In the example above, 4.5 uF + .5 uF = 5 uF. The combo replaces a 5 uF cap in the crossover.

Thank you Casouza :)

Out of curiousity, if they were connected in series, what would that do to the total value?

Thanks,

Steve

Steve, the resulting value is defined by the formula C1 x C2/C1+C2 , in this case about 0.45uf. BTW this is the same formula for resistors in parallel.
