Abstract
Abstract A multirange thin speaker assembly for installation in automobile doors and like constricted space installations in compact automobiles and the like with the front of the assembly facing toward the automobile interior, including a main speaker section having a speaker basket frame provided with mounting ears for receiving front mounting screws to fix the speaker basket frame against an interior wall portion of the automobile door. The main speaker section includes a woofer speaker unit and a bridge member supported from the basket frame carrying a tweeter speaker unit. A front grille panel of unitary plastic material has a pair of transversely spaced arcuate rear snap ring segments forming an interrupted annular ring projecting rearwardly from the panel to interfit in an anchor ring member carried by the basket frame, each having radially outwardly projecting bead formations to snap behind retaining shoulders of the anchor ring to fasten the grille panel to the anchor ring.
