I use the smallest ones on my Focal Sopra to raise the height of the tweeter (to get the 2’s closer to the height of the Sopra 3’s). They do that well enough and I think look cool. They don’t do anything to the sound, other than the sonic benefits I get from the higher tweeter height.
Love to hear from current owners or past users of Isoacoustics Gaia footers.
Do you still like them? Have you replaced them with something you felt sounded better in your system? I am considering purchasing a set of the IIIs, but am not sure I want to spend $400 on these footers.
