Abstract
A two-piece speaker assembly has a speaker base for permanent attachment to a cabinet and a detachable cone unit that may be removably attached to the base and replaced by a larger or smaller capacity speaker as desired. The separable base and cone units are threaded or provided with a bayonet-type of interlocking arrangement and biased with a spring to maintain a locked connection. Also, an electrical connection between the base and speaker cone is provided by a suitably-sized, contact-type of spring-biased terminals.
