A speaker stand has a base plate and a top plate joined to the base plate through a column. The top plate has speaker cushions at the back edge. A ground pillar extends through the top plate, the column and the base plate to the ground. The ground pillar is loosely clamped in the top plate by a foam rubber bushing, to limit lateral movement but allow the ground pillar to be decoupled from the structure of the speaker stand. Unwanted vibration from the speaker cabinet is drained through the ground pillar to the ground to minimize interference and feedback and reduce audio coloration.
