A novel shallow speaker has a novel spidercone coaxial with and optionally
having a radially inner spidercone flange suspended in a circumferential
adhesive well affixed to the former. An inner rearward flange of the flat
annular diaphragm is suspended in the circumferential adhesive well and
the well is filled with epoxy. The spidercone has a frustroconical
portion having a minimum radius smaller than the maximum magnet assembly
radius and a maximum radius greater than the maximum magnet assembly
radius. The spidercone has a spider portion integral with the larger end
of the frustroconical portion and attachable to the basket by a
tangential flange. The tinsel is interwoven with the spidercone in a way
that reduces the risk of breaking and shorting. The diaphragm is
substantially flat and coplanar with the top edge of the narrow surround
when at rest.
