If an 8ohm speaker measures 6, what would a 4ohm speaker measure? And more for the issue, what would two 4ohm speakers probably measure?
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?
