A flangeless mounting system, suitable for in-wall speakers and other components, includes a panel that is finished to provide at least a superficially continuous junction between the edges of the panel and the surrounding wall, ceiling, or other structure. A rim advantageously extends outwardly from a first surface of the panel by a small distance, which in currently preferred embodiments is about 1/16.sup.th inch to 1/8.sup.th inch. A collar is preferably installed about the inner edge of the opening, and a receiver is attached to the collar or directly to the panel. Magnetic, threaded, detent, and frictional means are contemplated for maintaining the component in position relative to the receiver.
