Crossover Component Selection for 3000 Hz/18dB

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.
