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

Amen! Nina Nastasia - The Blackened Air is playing right now. Wow!

These speakers are very respectable But,the Xovers are very lacking especially for 
Speakers including the Adagio the Xovers made in Taiwan ,I helped a friend  on the flagship and I  owned the Adagio the Audyn true Copper and Mundorf supreme caps are 3x in size as well in weight far better quality .for a few hundred dollars 
A dramatic upgrade across the board . My uncle is a pro audio engineer and knows the Chinese pricing model well being there several months a year.the cabinets at most 500 each and 250 on the Adagio a substantial  profit margin for even the drivers are made in Taiwan which 
Like tang band very good, but far less expensive then scan speak , seas,or Dynaudio. I am just stating  facts .I feel if  being charged  $5k and up I should get at least decent quality boutique Xover parts .Even Clarity ESA capacitors, and Mills resistors are a substantial upgrade in sonics at a minimal cost and still leave a very good profit margin .this is a pretty accurate statement. At least offer premium upgraded Xovers for just the price of the parts ,I think that would be fair.
When just being built easy to install .I had to take everything apart to modify to mount the bigger parts a lot of extra  work after they are built.

Steakster, I will give it a listen and thanks!

Audioman58, my thoughts exactly to be frank here. It was a ton of work putting in the parts that should have been used upfront after the speakers were built. Mills or other good resistors would have cost perhaps $3 each instead of $.30 cents each. A $20,000 speaker should use a $3 dollar resistor :)

I see this all the time in high end gear however and it does cause me to shake my head.

Audioman58, I still have the bass boards to upgrade. Each speaker uses two 1000uf, 100v caps. Yes they are low cost electrolytics. Any suggestions here? These boards have 8 ohm and 12 ohm 20 watt resistors which I will replace with 2 Mills MRA 12’s in parallel. But the caps? Not entirely sure a better electrolytic cap from Audio Note will help much here or not. Film caps in parallel would be very expensive and perhaps take up too much room. Not sure bypassing electrolytic caps with film bundles is advantagious on a bass crossover board. I know it works great in amplifiers, but crossover boards?

Does anybody knows the origin of the Crescendo drivers?
