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

Bill,
I suspect that in terms of sonic impact the tweeter and midrange capacitors are the sites to address compared to the woofer location.  Knowing how well the AZ Crescendos sound I'm eager to learn what these presumably superior parts do with these speakers. 

In my speakers merely changing the single Solen tweeter capacitor to a Duelund CAST reaped undeniable improvement,  just one capacitor in each speaker was all it took.

grannyring,
Hope this question is not intrusive but didn't you live in Minnesota? How did you find yourself in Tennessee? Any culture shock?

Well my wife and I are now empty nesters and we wanted to move to warmer climate and an area vital musically and economically. We did a ton of research and Williamson Country (Franklin, TN) just south of Nashville seemed ideal. We visited a couple of times and loved it. No state income tax, reasonable real estate tax, wonderful live music all around, great climate, nicest people I have encountered in any geographic area I have lived...

There is a spirit of creativity and entrepreneurialism that is wonderful here. Folks are happy and so much to do.

We love it here!

No wonder it is one of the fastest growing areas in the country and real estate prices are going through the roof! 

Bill,
Another Bill (Brownsfan) did the same several years ago moving from Indiana to TENN. He and his wife love it there and say the people are as friendly and nice as can be. I’m happy for both you Bills.

Thanks Charles! 

For you Crescendo owners this is not an upgrade for the timid. Getting the crossover board out is tight and requires patience. Not enough extra length or slack on the driver connections makes it difficult. Tight space!

Once it was out I realized I needed to buy more caps! All the parts are matched precisely thus I had to pay extra to do the same. 

I should be be able to finished the job next weekend once all the parts are in. I will take pictures and post also. So much easier to do this up front😬
