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 Grannyring i have the MK2s and would be very interested in doing these mods into outboard crossovers. Do you have pics of the original c/os as you mentioned they were upgraded to MK2. I could compare them to mine. For some reason i can't view the pics on this post nor your listing so i sent my email through your listing

Reviving this thread!!

I just took possession of AZ Crescendo MK1... and would like to have a parts/schematic of this GrannyRing-mod :)   Would be a fun project
The speakers were sold some time ago and I don’t have any notes to go back to at this point.
