The loudspeaker (50) is conventional having a pole (60) with a surrounding magnet (54) and pole plate (58) defining a gap therebetween and a voice coil (72) wound on a tubular former (64) disposed within the gap (62). The tweeter (10) comprises a diaphragm or dome (14) for producing sound having an electrically conductive skirt (28). The skirted dome (14) is supported by a support member (12) having a surface for attachment to the pole (60) of the loudspeaker and a plurality of points of support (22). A phase plug (16) is located on the opposite side of the dome (14) from the support member (12) and is connected to the support member (12) through an aperture (26) in the dome (14) in such a way that the dome (14) is locked in position whilst being free to vibrate, whereby the tweeter can be assembled before insertion into the host loudspeaker (50). |
