ABSTRACT:
A grille is attached to a woofer, and a tweeter is further mounted on the grille to mutually face the woofer and be at least partially disposed in a cavity defined by the woofer and grille to define a compact loudspeaker structure. The grille and a back of the tweeter face an environment to which sound is to be directed, and both contain structures and are arranged to allow sound from the tweeter and woofer to communicate with the environment, while resisting water from contaminating the woofer and tweeter. Further, the rim of the grille and a frame define a component storage space in which elements which constitute a dividing network or other discrete electronic components of the loudspeaker are housed.
