About to solder the tweeter compensation resistors together, along with the capacitor. I hope this diagram is understanble, but want to make sure I've got it before I commit solfer.

The diagram below should represent 4 pairs of 16 ohm resistors in parallel serial combination.

Not sure if this is what your looking for, but I think it is.

OK - I'm ready to fire up the soldering iron - well almost.

I sharpened my pencil, diagrammed the compensation network based on the 4 Pi schematics Wayne sent me - lots of lines connecting the resistors (series/parallel), and built a 3 dimensional model out of cardboard. I then looked at the URL sent to me with the attached graphic:

http://www.audioroundtable.com/PiSpeakers/messages/13262.html

and modeled this out of cardboard - and they are two different beasts.

So, if I duplicate the compensation network based on the picture provided via the URL - I feel like I should be Good to Go. It will be connected to the Eminence PCB.

The woofer compensation network looks easier - connect the dummy resistor to the capacitor, and connect the leads in parallel prior to connecting to the woofer.

I have a suggestion. When you build-up your cluster of four resistors to make R1 and another four to make R2, measure them with a DVM to make sure the result is 16 ohms for each one. It's just a series-parallel connection that is physically shaped in a way that's convenient.
