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.

How do you like these speakers and what else are you driving them with? Jeff
Loved the 40.1’s! We moved to Franklin, TN and downsized. I lost my dedicaded music room and now share a space in our main living area. The home is new with cool tone colors like white kitchen, light gray walls, black granite etc... and my wife felt the Harbeth’s just didn’t work in the space aesthetically. I also agree though hard to admit:)

The good news is I have always loved the Crescendo speakers and was lucky enough to get a used set in gloss black that my wife also loves. (Great price also)Turns out I like the Crescendo even more 😊

I looked inside the speakers for the first time and like most $10,000 - $20,000 speakers I have taken apart I saw sand cast resistors and other obvious places that could be improved. Still blows my mind that a speaker of this expense uses 89 cent sand cast resistors that any good DIY guy knows sound just ok, and a tad harsh in the highs compared to a Mills MRA for example.

I love the speakers and will leave most of it alone except for the resistors and caps on the tweeter and mids. All else will remain the same. I assume the film caps used are middle of the road at best based on the resistors and inductor quality used. I am not certain, thus my question.
