Check each coil one at a time. Maybe the second one is open circuit and not changing anything when connected?
Here is the thing with Dats, the silly alligators make for some wild readings depending on the weather, time of the day and the neighbour's underwear colour. I found it very difficult to get the reading for the racer. Check your connections inside the box too
Should I replace the alligators with those needle nose stronger units that I got in?

These lil beasties. I'll replace the stock alligators with these and also like this one

This is my fault….
REW is often complaining when I take measurements through the dats due to insufficient output levels, etc.
Works fine if I use an amplifier.
I dunno why it shows a previous measuremebt (again) (or why the drastic change in TS parameters with the single voice coil and RE would be ‘the same’

True, I have the best results if I wear floral print bikini briefs. I don’t have any issues with the dats or electrical connections, but sometimes I have to restart the laptop(I’m computer illiterate)
More than 6dB difference using a single vs dual other than in the 50Hz range, that's even more than I'd have expected.
Have you checked if there is a difference in the response between the two single coils, in other words, does using only the inner or outer coil make a difference in the motor force?
Before we try and work out the differences, what is your full signal chain?
And what are you hoping to measure and how?

OK, after the remeasure, the difference is around half as in the measurement in #7.
Just the scales were changed to confuse those who should use reading glasses...
I assume the DATs doesn't have the power to push a driver that's loaded in a box, hence the variance
Does anybody know how to set the 'Upper Z Limit' to a value higher than 10kOhm in the DATS software? I'm trying to measure guitar pickups and some exceed 10k!
Do you have an example guitar pickup impedance curve that you can show us? That might be helpful and give us a better idea as to what's going on.
One way to get around the 10kΩ limit on the plots from DATS is to include a 4.7kΩ resistor in parallel with the guitar pickup. When the guitar pickup had a 10kΩ impedance, that would drop the composite impedance measured by DATS to around 3.20kΩ. When the guitar pickup had a 1kΩ impedance, the DATS measurement would be about 0.82kΩ. With a little bit of spreadsheet work, it would be possible to compute the actual impedance value of the guitar pickup, noting that the impedance will include a reactive component as well as a resistive one.
