A speaker support for elevating and supporting a speaker comprising a base, at least three support dowels attached to the base and extending upwardly from the base. The dowels include a first support dowel located laterally between second and third supports dowel that are both spaced forward of the first support dowel. A support shelf extending forwardly from the support dowels and having openings corresponding to the support shelf to be vertically adjustable along the support dowels. The support shelf tends to pivot about the support dowels when a speaker is placed on the support shelf, causing a locking action at the support shelf openings and the dowel supports which prevents the support shelf from moving downward on the dowel supports.
