Default How do you test speakers with this jig?

Is there a "cookbook" that tells how to do this similar to the "manual" Zaph laid out for Sound Easy?
Any technology sufficiently advanced is indistinguishable from magic

Sorry to all for the long delay.
I will get back into the swing of things shortly and your continued patience is appreciated.
The jig is a modified version of the Wallin jig and the use of it is nearly identical. There is a ton of documentation on using Speaker Workshop with a jig like this. HERE is a good place to start.
I'll get the setup thread on track as soon as possible.

Any word on the user's manual thread? I just finished assembling the board and everything seems to be ok. Can't wait to start making impedance measurements.

Please let me finish posting all of the instructions before you contribute or ask a question.
First, I know this is an old thread. It's also apparent the maker of this jig never created the user manual he promised. As I recently purchased an unassembled jig kit and it actually works I'll be happy to share what I learn and have learned as I go starting with getting it working.

If anybody still has one of these jigs and didn't get it to work the instructions left out two very important PARTS-SIDE jumpers that are marked on the board but not mentioned in the instructions. I fussed with the one I recently purchased and only noticed that in the pictures there are jumpers on the board where they are outlined in white but they aren't mentioned in the instructions. Once I installed the jumpers it seems to work fine.

Also of interest, I decided to use a full 24v PS and although it seems to work fine the resistor for the LED (R1) is only 1/8 watt and starts to get hot and stink after only a a minute or two. Thankfully the transformer I bought is a 24v secondary winding with a center tap so I can just switch to 12v and not have to replace the R1 resistor but it seems the only solution is to replace it with a 1/4 or 1/2 watt version. I haven't seen any other issues with the jig so far.

If anybody has one of these and is using it can you verify the IMP measurement procedure?

It seems the logical way to do this is with only 1 set of probes. It would seem obvious to get two dual banana connectors (red & black) and place one between both RED test lead plugs and the other between both black plugs. Then run the testing leads (12Gauge Monster wire?) down to the speaker for testing and clip them on. This should use the jig amp to excite the speaker and the IMP line-in to measure it. I was hoping I wouldn't need to purchase two sets of test leads. Monster wire is very expensive.

Default Monster wire

you don't have to use monster wire. You can go to your local electrical supply and pick up 2 different color 12 gauge stranded wire and twist them around each other for noise rejection.

I have one assembled that I used a few times, I'd be willing to sell it for the original price. Meaning that I wasn't trying to sell it, but if somebody wanted one and they'd get more use out of it, then I guess I don't mind selling it. Mine is painted with Rustoleum "hammered" dark grey semi-metallic paint. If you're interested I could take a picture of it later this week.
