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

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.

Were you able to get a meter reading off that resistor
Any blown caps
Any electrical burnt smell
BTW There's no shame in color blindness

Works well if the resistance value has not changed due to fault.
Yep so 2,2, 0.1 multiplier, +/- 5% tolerance, 20ppm/k temperature coefficient.red,red,gold,gold,green is there a possibility of color blindness

I think he was just using a screwy calculator or something
I have an old cardboard one around here somewhere
Plus I think he was reading the color code backwards

That's where I started
but now I'm on a Scotch Whisky blend and we know where that's headed

Yes i know i f#€€€ up
I do not do this things .
Its a 4 band with a extra temp.
We do not use them here .
So reason i do not fine them in the store.

don't sweat it were all adults we don't give a crap anymore

I always say.
You always learn somting new again .
Just be open for new input good or bad .
Its how other see thare information .
Soon i gone order a kit and than fix it.
Its not for me its for my Little brother .
That is have sent those speaker 5 years ago new. .
So for him its s emotion thing to.
I have the solder station compleet with a heatgun.
So solder will not be a problem .
I will set picture here in the topic just for the fun .

Well good luck I hope you get it all sorted out.
It's a satisfying feeling of accomplishment to fix something whether it's a piece of crap or valued at thousands same feeling.
I'll watched for the pics

I have replace it
Systeem dit not go on.
For now i set it away and bring it to a repair shop.
Or i have to thake me oscilloscope.
And test is all if i have time.
I have now set jbl active studio monitors set for him.
So he can have music again.
So he is happy .
Not the fix i like but he have nothing so it have to do.

It's rarely ever just one component anyway usually a combination of caps possibly a fet
I've been knowing to take a hammer to attempted repairs that did not work out just to prevent myself from wasting more time on that project at a later time
