Open the speaker and take a detailed picture of the broken knob. Most important is if it has any letters printed on it. Only with that information we would be able to find a replacement.
Alternatively, if you already figured out which part it is, we could help you to find a replacement part!

Ummm unfortunately this is not enough to find a proper replacement.

The R103 might mean 10 kOhm. Typically, the last number means the number of ceros you add to the first numbers, but this is not always followed by all manufacturers.

Having a quick look in one of my fav distributors https://www.mouser.co.uk/c/passive-components/potentiometers-trimmers-rheostats/potentiometers/
+
+
There's one that matches in shape and color: https://www.mouser.co.uk/datasheet/2/414/TTRB_S_A0009241252_1-2565491.pdf

It sheems the metal shaft and the footprint are similar to the ones on the pictures. However, before you can conclude if this is a suitable part, there are other features on the potentiometer that needs to match with the one that you have: resistance, number of detents, if linear/log, etc...
+
+
I also see that the potentiometers are wired and connected to the board? Can you confirm that?
+
+
Besides, have you tried to turn on the speaker? Does it work electrically? I mean, has the knob broken mecanically, electrically, both?
+

If the knob if only broken mecanically, and given that it’s hard to find a replacement… Have you consider fixing the knob instead of replace it? With a proper epoxy, it might look like new… https://www.jbweld.com/product/j-b-weld-syringe
