KEF reference spike feet size - why are there two sizes of spike/feet plates?

[morethinkingcapacityneede]

Hi there. I am trying to work out what some of the accessories of a KEF reference speakers are. As far as I can see, there are two different sizes of spike plates/feet for when the speakers are placed on a hard floor (see photo). Any insight on why this might be would be greatly appreciated!

Perhaps the ones on the right are the caps that go on top of the feet?

Unfortunately not, these are separate items. I've highlighted the duplicate feet in the manual sketch.

It's to tune the sound.

Let us know when you find out.

so, in the end, I figured it out, the second set of feet do not belong to those speakers. the space in the accessories box is for the bolts attaching the leg stand to the speaker base. see example
