Relative to 500 ohms 5000 ohms is a high impedance. It is ten times higher.
The real impedance is the resistance in ohms more 20%. A coil resistance of 6,7 ohms X 1.20 = an impedance of 8.04 ohms. If the voice-coil had exactly 8 ohms, the impedance would be 9.6 ohms and the sound would be unclear, tending to more basses.
Never haerd of a 10 ohm radio. There is no 10 ohm radio amplifier on the market, when you think that must be the output impedance of the amplifier. The output impedance of a radio amp is always less than 0.5 ohms. Scroll down to related links and go to "Voltage Bridging or impedance bridging - Zout < Zin"
I believe the ohm meter will read about 90% of the true ac impedance.
A: [practically all commercial digital meter have a 11 mega ohm input impedance but there are special meters that can be used to measure leakage current and they have impedance high enough to measure nano amps. Even an oscilloscope will have these kinds of impedance such that the reading is not influenced by external loading

the impedance of a speaker is a characteristic that is has. A 4 ohm speaker will always have a 4 ohm impedance and it cannot be changed. If 2 speakers of 4 ohm impedance are wired in parallel, then the total impedance will be 2 ohms. Similarly, if you wire 4 speakers together, the total impedance will be 1 ohm. Wiring a 2 ohm speaker to an amplifier rated to drive a 1 ohm load should work without any problems but expect the total power output to be somewhat lower than with a 1 ohm load.
Impedance, resistance, and reactance.
With system you mean the output impedance of an amplifier. No Problem to do this, but there are really no amplifiers with an output impedance of 8 ohms on the market. All loudspeaker amplifiers have an impedance of less than 0.5 ohm. Scroll down to related links and look at "Impedance bridging - Wikipedia".
No Problem to do this, but there are really no amplifiers with an output impedance of 4 ohms on the market. All loudspeaker amplifiers have an impedance of less than 0.5 ohm. Scroll down to related links and look at "Impedance bridging - Wikipedia".
AnswerThe unit of measurement for impedance is the ohm.

You can use your so called "4 to 8 Ohm's output" amplifier for your 10 ohms loudspeaker. All amplifiers have an output impedance of less than 0.5 ohms. You use impedance bridging when you connect the 10 ohm's loudspeaker. The "4 to 8 Ohm's output" means only that a 4 to 8 ohm loudspeaker will be adequate and not that the output impedance is 4 to 8 ohms!

Never heard of a 16 ohm hifi aplifier. All amplifiers have an output impedance of less than 0.1 ohm. We use always impedance matching with a low source impedance to the much higher load impedance. Scroll down to related links and read "Amplifier, Loudspeaker, and Ohms".
There is neither 4 ohm nor a 8 ohm output of an amplifier. Less than 0.5 ohm is the output impedance of a loudspeaker amplifier. Scroll down to related links and look at "Voltage Bridging or impedance bridging - Zout < Zin".
