IsoAcoustic Gaia III with Focal Sopra 2

I purchased the Gaia III from upscale audio for use with the focal sopra 2 speakers. 
Is it possible to thread these into the Sopra 2's? The thread size seems much too small. It looks like a thread large enough for the Sopras would be too large to fit in the Gaias. 
I have an email into IsoAcoustic as well so will post those results when I hear but thought I'd ask the community here too their experience since it seems very many have the Gaias.
