(57) A ring radiator for a loudspeaker has an annular inner portion (24) and an annular
outer portion (22) and a tubular former (24c) carrying a coil (28) and positioned
at the junction of said portions. Instead of securing the former to the radiating
element by a butt joint the former is here made integral with at least one of the
portions (e.g. 24a, 24b) of the radiating element. If integral with just one portion
of the radiating element, the wound component is then secured to the other portion
(22), preferably by an adhesive lap joint.
