For hundreds of "8 ohm impedance" speakers I have measured 7 ohms DC.
For many "4 ohm impedance" speakers I have measured 3.2 ohms DC.
But this "4 ohm impedance" speaker measures almost a dead short DC.
The voice coil of a speaker is a coil of wire that has a fairly high resistance. The impedance should be a little higher than the resistance. Or you could say that the resistance should measure a little less than the impedance. But not this low. I think something is wrong with this speaker.
I always saw the DC resistance to be just a shade under rated impedance as you have also posted.
I think it's likely this speaker's voice coil is hosed.
