IsoAcoustics GAIA isolation devices are designed for floor standing speakers and provide superior acoustic performance with enhanced sound clarity. Featuring stainless steel construction and finished in an elegant dark chrome housing, GAIA incorporates patented design principles to provide a high degree of isolation. Optimal results are achieved by installing the GAIA isolators with the logo facing the listening position, or rotated 180 degrees, to align the isolators with the speaker’s motive forces.
Compatible with floor standing speakers weighing less than 70 lbs each, the GAIA III comes with three different thread sizes: M8, M6 and ¼-20. 
Sold as a set of 4.

“the Gaia’s made an across the board improvement in sound… a tightening of the bass which also seemed to go deeper …instruments and voices were more precisely defined on the soundstage, which itself was wider and higher I have no reservations about their effectiveness…A remarkable product” — Stereophile.
