The Filter design for Zaph,s Hi-Vi B3S single driver system

[zei]

Ok, i,m a complete beginner in this diy thing.

I am wondering if someone can explain what a "The cap is a Bennic poly" is?
i need it for the filter design and i can,t find it anyware.

I understand that it dont have to be a bennic or even a 4,3 value since i can put a 1.0 and a 3,3 in pararell..

However.. What does Poly meens??

In Swedish i can see more than one option for Poly so i need to know exact.

Polyester
Polykarbon
Polypropylen
polyfenylsulfid

very greatful for the help.

Best regards

I believe Bennic is the brand. Probably looking at the physical size you can figure out what kind of poly it is, or look up the web site. The better material are generally larger for the same cap value.

I am sure "poly" refers to polypropylene. In the US when polyester is used it usually is referred to as Mylar. The other items beginning with poly are not used in speaker filters.
