Depends on the voice coil, but the 6 Ohm measurement is fairly typical- could be 6.2, 6.4, etc. 4 Ohm drivers often measure around 3.2 Ohms- if you're asking about two 4 Ohm speakers wired parallel, most amps won't like that because the minimum impedance will likely activate the protection circuit.
What's the application- in-ceiling speakers?
It’s in ceiling Def Ted speakers on a C4 amp. The amp is rated for 2ohm, and they say it’s safe down to 1.6ohm. But the guy drives them at almost full power with streaming music. So it’s probably dipping below 1ohm in the crescendos. I think it’s just a bad combination of everything and not a bad speaker.
