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

@audioman58

Like your thoughts on my question above. Thanks much.  

Charles is right on the mark.

Granny,

Why not bias the electrolytic caps in the woofer cross over all you need it two  (4 for the set) more 1000uF capacitors which Madisound sells,  put them in series with the existing capacitors then bias the mid point with a number of 9V batteries in series, four should probably do for 36V. Positive goes to the midpoint via a 1M Ohm resistor negative goes to ground.  JBL use this technique in their flagship speakers 

Alternatively buy 40 100uF metabolized polypropylene capacitors - with that quantity you should be able to get a discount :-) 


Best of luck

Peter thanks so much for the post. This is new to me and I need to learn more about it. I will see if a can become more familiar with the idea and implementation. 

@pbnaudio 

Have you done this? I ask as I wonder if this will make these cheap electrolytic caps sound as good as decent metalized  poly caps? Very interesting.

So I hook up 4 nine volt batteries in series with the positive lead of the first battery going directly to a 1mohm resister then to the junction point of the series caps and the negative lead of the last battery going to the negative return of the low pass circuit. That simple? I better test that no DC is getting through. The electrolytic caps should be non-polar correct? 

Thanks!
