Historical Context
The LE5-2 was designed for the 3-way layout of the L100. It runs between 2.5 kHz and 7.5 kHz, the midrange band where human hearing is most sensitive. The back is sealed. That mattered in the L100's bass-reflex cabinet, because it kept the rear wave of the woofer from interfering with the midrange cone.
