subwoofer

   Also found in: Dictionary/thesaurus, Acronyms, Wikipedia 0.06 sec.

subwoofer

A speaker that reproduces the lower end of the audio spectrum. A subwoofer system may include a crossover circuit which switches frequencies at approximately 100Hz and under to the subwoofer, while passing the rest of the signal to the main speakers.

Unlike front, center and surround channels, where speaker placement is critical to the listener, subwoofers are non-directional and can be located anywhere in the room.
