It really is very simple, but many ignore the fundamentals of, Blu-Tack® (made by Bostik Ltd.), room placement and toe-in. There is a popular belief that cones or spikes are the best interface between speaker and stand, not for Foundation stands. They require a direct link to transfer the distorted low frequency cabinet harmonies into the stands and 'Formula Fill’. The ‘Formula Fill’
is enclosed into the stands and protected by means of Foundation stickers. Never try to remove the stickers. The ‘Formula Fill’ will be disturbed, leading to detrimental of sound and void of warranty. Four pieces of Blu-Tack® per stand, roll each into 5mm balls and place one at each corner of the top plate. Your speaker is pressed firmly onto these balls, the Blu-Tack® should spread out to 1mm thick, any thicker, you have not pressed hard enough, thinner is OK.
