A sealed speaker enclosure for a bass speaker that is hand-insertable and removable from a hard-side motorcycle saddlebag. The body of the enclosure complements the interior space of the saddlebag making sealing contact with the interior walls of the saddlebag. The bass speaker faces the motorcycle side of the saddlebag within the shock absorber tower indentation overlapping and opening. A speaker grill overlays the opening in the shock absorber tower indentation of the saddlebag.

The exemplary embodiments herein provide a motorcycle saddlebag security enclosure assembly having an enclosure with a substantially flat top panel, an access door substantially parallel to the top panel, a bottom panel positioned below the top panel, and a plurality of side panels which connect between the top panel and bottom panel. Embodiments further contain a base adapted for removable attachment to the enclosure and having a substantially flat base plate, and a plurality of legs extending downwardly from the base plate. Preferably, a hook extending upwardly from the top panel and a pass-through aperture is placed on the same side of the enclosure as the hook. A C-shaped base element is placed beneath the base and near a central portion. A U-shaped channel extends below the top panel and accepts a sidewall of the access door.
