Well, since there is no "General Speaker" forum here, I figured I would post this here since I know many of you who hang around here, and since FR rules! 
I have resisted trying to set up a Thiele/Small Parameter testing system because I had assumed it was far too complicated/difficult to do.
Recently, however, I stumbled onto a post in another forum where a guy was talking about how easy it is to do with Ulrich Müller's "audioTester 3.0".
I downloaded the pdf user guide first, read through the section on measuring TSP and thought "I can do that."
That evening I dug through my random parts and found a 10 ohm resistor, a 3.5mm male to 3.5mm male headphone cable and a couple of spade connectors. Before long, I had my "circuit" soldered together (more of a custom cable, really) and it all checked out with the ohm meter according to the diagram in Ulrich's PDF.
Once the "cable" was done, it was literally a matter of plugging one headphone jack into the line-level out of my sound card, the other headphone jack into the line-level in of my sound card and the speaker spade connectors to the driver terminals. (I coloured the jack destined for line-in with a blue sharpie and the other end was already green, to match line-out).
Once hooked up, you just run the program, set your input and output devices, sample-rates, etc. and then follow the directions in the PDF. For initial testing of the cable and application to see if it worked, I just used a "loonie" and some tape for the second run. Today, I picked up some Play-Doh and a new battery for my digital scale, then weighed out 20g of the Play-Doh. This worked better.
Anyway, for anyone who wishes they could measure TSP but who finds it intimidating; just jump right in. It is easy.
If anyone would like, I can take a photo of the cable I made and post it here.
