They looked like armadillos boinking a mailbox, and yes, they were speakers. They were virtually indestructible. They hung on the inside of your car window when it was freezing outside and wouldn’t allow you to roll it up all the way.
They were also easily stolen with a pen knife. Lupe had a wall of them in his apartment, all wired together and hooked up to his stereo for a tinny wall of sound. Listening to Led Zeppelin through a dozen drive-in rattlebuzzers was truly something to behold. Truly.
