Crossover capacitor voltage ratings....


Hello,   I recently started to replace my +20 year old electrolytic capacitors in my PSB Gold i's and have hit a snag.  There are four 100uf 100v bi polar electrolytic caps in each crossover that need replacing.  I found three prospective companies with "audio quality" caps that I may go with for the job.

*Audio Note Kaisei 100uf 100dcv*   or    *Elna RBD 100dcv*   or   *Mundorf (raw) ecap 100uf 100dcv*

Question is....the new caps I just listed all have a voltage ratings as "100dcv".   I assume that this refers to DC current.  So, would the "100dcv" ratings be good-to-go in the crossover where the current capacitor are rated simply as "100v"??  See the issue?  Or should I seek out a voltage on the new cap which is slightly higher?  Or even rated as "100acv"?  If that's the case the pickin's get slim indeed...    Wheeew...

Note:  if any opinions on the above capacitor's sound please chime in!!                Jon

Chills,
Bill  (grannyring) is very experienced and knowledgeable in these matters, I'd give much regard to his recommendations. Solen is a solid choice and reasonably priced however you can find better. My speaker's simple crossover used a single Solen capacitor at the tweeter. How did it sound? Very good. I replaced the Solen with the Duelund CAST and as a result, very good became superb!

Duelunds are fairly expensive and not practical for all upgrade applications.  The alternative capacitors listed by Bill are worth investigating and are affordable compared to the Duelund. Any of the these would be a noticeable improvement over your current electrolytic capacitors.
