Guys, you can get in touch with Johnny at Audioconnection about footers for the Proacs. He's sold them for many many years and has a great idea of what the footers will do or not do with the specific speakers. The thing to remember is that footers, like anything else, will change the sound, but not always for the best. It is all dependent on the speaker, the floor they sit on etc... So far, the HRS footers/cones seem to be the best with most of my friends IRT an overall helping of the sound with various speakers in various rooms. I have 3" granite plinth that has a silicone 'glue' joint. It is an amazing upgrade that I've heard on a friends pair of Vandersteen's. I have yet to install mine as I need other to do the work as I can't move heavy things anymore, lol. :).
