I'm a newbie on this site, and I'm trying to build my first passive crossover.
I've chosen to put together a high-pass filter for a 4 ohm speaker at 3000Hz/18dB.
According to several sources, I need to acquire a .16mH Inductor, an 8.8uF cap, and a 27uF cap.
My problem is I'm having trouble finding parts of exactly the values I need. I've found a couple of .15mH Inductors (the Jantzen looks nice). I've looked at several 8.2uF caps, and even a 9.1uF, but no 8.8uF. I have found a 27uF cap.
My questions are:
1. Am I correct in assuming I'd better get EXACTLY the values described?
2. What is a good material for a mid-priced capacitor?
3. Where can I FIND this stuff?
Thank you for the assistance.

Hi,
The only several sources that will agree what you need for 4 ohms are all
wrong. They will be more right with a zobel added to the bass/ mid, but
3rd electrical doesn't tell you what the resultant acoustic response is.
It depends on the application how serious a problem this is.
