I don't recall the speakers in the show, but the differences between the 4311 and the L-100 were largely cosmetic. The 4311 had the woofer on top (since, as a "studio monitor" it was often placed on a shelf, close to the ceiling) and had the midrange and tweeter controls on the front and bottom of the speaker. the L-100 had the familiar "egg-crate" foam grille, in a variety of colors (the most popular of which was brown).
