I think the measurements were made on a single driver. If one were to

anyone know what's the inherent variability due to manufacturing,
realizing that it probably differs to some degree. How much variance
for say a woofer would be considered acceptable?

I just replaced a driver in an SR cabinet.

The 'new driver' had 4.1 Ohms DC resistance and the 'old' one had 4.8.
Manufacturing tolerances I imagine.
