Abstract
A loudspeaker unit is provided for attachment at an elevated position within a listening space. It has a drive unit for producing a beam of treble sound, and a sound mirror that distributes a beam from the sound unit over a wide angular extent both horizontally and vertically with a generally consistent amplitude of perceptible sound. The unit may further comprise an angled mid range and low frequency drive unit. The unit demountably clips into a support bracket that can be carried by a post or fixed directly to the wall. Signal supply is via connectors in the bracket so that as the unit is clipped in place, the electrical connections are established. The speaker is quadrant shaped when viewed in plan and lends itself to installation in groups and clusters (FIG. 13).
