A woofer or bass speaker is a technical term for a loudspeaker driver designed to produce low frequency sounds, typically from 50 up to 200 Hz. The name is from the onomatopoeic English word for a dog's deep bark, "woof" (in contrast to a tweeter, the name used for loudspeakers designed to reproduce high-frequency sounds, deriving from the shrill calls of birds, "tweets"). The most common design for a woofer is the electrodynamic driver, which typically uses a stiff paper cone, driven by a voice coil surrounded by a magnetic field.

type of loudspeaker

electronics component

coil of electrical wire attached to the apex of a loudspeaker cone or dome, produces magnetic field due to the electrical sound signal which interacts with permanent magnet and makes the diaphragm vibrate and produce sound

magnet made of ferrite material

thin, semi-rigid membrane that vibrates to produce or transmit sound waves

The speaker concept set out transparent and natural sound as the goal, and the achievement of the result is widely acknowledged.
