Thread size for Footers for CR1’s?

[Avidlistener]

I’m interested in adding aftermarket footers to my CR1 stands. Can anyone tell me the thread size? Thinking of the Isoacoustic gaia, but open to suggestions. Also since the make the speaker higher, should I use a longer thread on rear footer so it’s higher, pointing the mid/tweeter back at ear level, since the footers will raise the driver above ear level?

For CR1-TX, the stand thread size is M6. Should be the same for previous generations as the stands are the same

Thank you so much. What footers have you tried? Have you used ones raised in the back angle tweeter towards ear height?
