Apart from it apparently being built a bit like a segmented Cubo (with a response curve to match), it seems to use an inline electronic circuit referred to as "voice coil tracking protection", which apparently is supposed to protect the driver's voice coil from overheating. Any idea if this works as expected?

Interesting ! I designed an electronic circuit several years ago that was meant to also protect drivers from being overdriven. It was also powered off the signal & to be built into the box. Though mine was a different circuit.
Yes the Dynacord should work as expected, If it doesn't they'll be in trouble 😀 When the voltage reaches a predetermined level, the relay switches in the series of lamps to reduce the power to the driver.
I'm surprised more vendors havn't done this before now, as for a few $ or so, returns under warranty would be minimal. Plus users wouldn't blow up their speakers 😉
