Hi. Can I use coils like these in a notch filter?

Hi Bo,
Unfortunately it is not possible to use this type of inductor in loudspeaker crossovers. If you have any technical knowledge, the following link explains why.

Hi. Excellent info. Thanks Best regards /Bo
You could use the coils in series. What of their value? It isn't marked correctly on the listing and they likely have too small inductance to be useful.
Hi. It says 1.2mH in the title. The copy lower down on the page has a typo. I think... Dont know if its 1.2mH per winding or both in series? Dont have a multimeter that can measure that either
Best regards /Bo
mH? I thought it said MH. These types are sometimes uH. (milli, mega, micro sometimes are mixed up)
To be sure maybe you should look at something that was wound with a crossover in mind, or do you have some of these already and are trying to do something with them?
Hi. Thanks for the clarification. I was searching for 1.2mH on eBay and these popped up. Im gonna drop that thought and go for regular speaker filter coils instead

Wiring the inductors in the same core, quadruplicates (*4) the single inductor value.
Hi. Good to know. Thanks
Regards /Bo
