A wall-mounting loudspeaker support has two spaced arms 19,20 upon which sits a speaker support element 11 having a flat upper surface 23 and a part-spherical lower surface 24. A rotary locking element 29 located below the arms may be tightened or loosened by way of a nut and bolt 39,40. The assembly of support and locking element can slide along the arms and the support element can be oriented to a desired angle on its curved surface within limits allowed by a slot 27 in its base and through which the bolt passes. |
