To solve my problem of pc speakers being not loud enough was to buy MegaMaxx speakers. They're loud but they sounded terrible

What bothers me now is the way the speakers are built, they have no sign of openings other than the screws where the speakers are mounted infront. The top walls, all sides, and bottom are painted sealed with no screws or nails on the corners. In case of needing repairs, how do you open these speaker boxes? Anyone knows how? Thank you.
