Abstract: An adjustable mount for a loudspeaker having a plate adapted for mounting on a surface or the open side of a junction box. The plate has an indented part-spherical surface which accommodates a ring with an outer part-spherical surface. The ring has an aperture extending therethrough and an elongated slot, and a first hollow tube is rotatably disposed in the aperture and a second hollow tube is translatably disposed in the slot. One of the tubes extends through an opening in the recess of the plate and the other tube is mounted on the loudspeaker with the conductor for energizing the loudspeaker extending through the first and second tubes. A web extends radially inward of the ring and has bifurcations at the end thereof disposed on opposite sides of the portion of the conductor between the first and second tubes. The first and second tubes have external threads which are engaged by locknuts for securing the ring on the plate and on the loudspeaker.

Abstract: A power selector assembly for a loudspeaker includes in one embodiment an audio transformer upon which a printed circuit board (PCB) is mounted via connector strips having pins for both securing the PCB to the transformer, and for individually electrically connecting foil contacts of the PCB to the multi-tapped primary and the secondary windings of the transformer. The transformer is mounted within a housing. An electrical wiper contact is resiliently mounted between the PCB and a knob retained in an access hole through the housing, for permitting the knob to be rotated for positioning the wiper contact to selectively electrically connect a foil terminal receiving an input signal to one of a plurality of contact foils of the PCB, for connecting the input signal to one of the taps of the primary winding associated with a desired power level. Other electrical connections on the printed circuit board provide for connecting a loudspeaker to the secondary winding.
