I think you may be reading that backwards I believe it is 2.2 ohm + - 5% the first gold band would be 0.1ohm multiplier

Not my fuel of expertise but those 2 bands look to be gold and I know gold is tolerance level and a multiplier It followed by grain that would be your temperature coefficient
Anyways I'll be interested to know what you find out

Wel the junk calculation from a app you can trow in the trash can
Its a 2.2ohm
Or a
E192 .
And that is a 2.24m-ohm
See the last one .
If its not gold but yelow
Resistor color code calculator - 3, 4 and 5 band resistors
3, 4 and 5 band (value to color code and color bands to value) resistor color code calculator.

red,red,gold,gold,green is there a possibility of color blindness

No its more if this is a product of china .red,red,gold,gold,green is there a possibility of color blindness
Wel the color can be wrong .
So wat i go do is this .
I gone open the other active speaker fluid f5
And solder the other one out .
Just to be sure
And no i'm not color blind
Its just that this speaker is not cheap.
And are not beult ,so you can not replace it .

Its often very difficult because the colours can fade or age, and look quite different from different manufacturers.
Is that white or grey ? Is that red, or orange, or maybe its supposed to be brown ???
Only real way is to measure it with a multimeter, that will get you very close, except for very low resistance values.
If its less than a couple of ohms, you can then probably figure it out from the colours once you know its a low resistance value.
One way to measure very low resistance values reasonably accurately is to pass a known current through the resistor using a bench power supply.
For example 100mA. Then measure the dc millivolts directly across the resistor, and use Ohms law.
If you use one Amp, its possible to measure down to a very few milliohms of resistance quite easily.
