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.

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.

Bill, I look forward to following your progress with this project. 
Curious to see how much improvement you'll extract from an already excellent speaker.  This will be illuminating.
