Acoustic Zen Crescendo speaker crossover capacitors ... who makes them?

I own the MKl version of the Crescendo and see the crossover uses all Acoustic Zen branded capacitors. Most are blue in color with the smallest values bring black. Does anyone know what company makes these for AZ? I did email the builder, but no answer. Love any information the community may have on this topic.

Hi Bill,

On the one hand you certainly have to admire the talent of Robert Lee using very low cost passive parts and getting such truly high quality sound. A quite talented builder with excellent design and execution of the Cresendo.


However I do see your point and agree that the wise selection and placement of high quality resistors and capacitors will yield more from this fine speaker. Those passive parts do sonically matter. No harm in making something "very" good even better with thoughtful part upgrades.

Yes Robert’s design is not in question as the speaker is awesome. The crossover is very complex with many parts. 15 resistors and 13 capacitors per speaker with many additional inductors. Easy to see why one could not use Duelund level parts!

That speaker with Duelund quality parts would retail for 35 K easily. Bill that is quite a complex crossover.

Ha! Yes indeed. I putting a game plan together. Most of the caps are polyester types (MET).  Better MPT caps are used on the mids and tweeter.

Seems nobody knows? Well I have decided to go with Duelund CAST resistors and deciding between Jupiter HT flat stacked caps or perhaps Jupiter VT round caps.
