Woofers

A woofer is a technical term for loudspeaker driver designed to produce low frequency sounds, typically from 60 Hz up to 250 Hz. The name is from the onomatopoeic English word for a dog's bark, "woof"[citation needed] (in contrast to the name used for speakers designed to reproduce high-frequency sounds, tweeter).

A woofer is a technical term for loudspeaker driver designed to produce low frequency sounds, typically from 60 Hz up to 250 Hz. The name is from the onomatopoeic English word for a dog's bark, "woof"[citation needed] (in contrast to the name used for speakers designed to reproduce high-frequency sounds, tweeter). 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. The voice coil is attached by adhesives to the back of the speaker cone. The voice coil and the magnet form a linear electric motor. When current flows through the voice coil, the coil moves in relation to the frame according to Fleming's left hand rule for motors, causing the coil to push or pull on the driver cone in a piston-like way. The resulting motion of the cone creates sound waves, as it moves in and out. At ordinary sound pressure levels (SPL), most humans can hear down to about 20 Hz.[1] Woofers are generally used to cover the lowest octaves of a loudspeaker's frequency range. In two-way loudspeaker systems, the drivers handling the lower frequencies are also obliged to cover a substantial part of the midrange, often as high as 2000 to 5000 Hz; such drivers are commonly termed mid woofers.

    SB Acoustics woofer (aluminum cone woofer, 8 ohm impedance) cone was formed with geometric features to reduce resonance and improve rigidity. The woofer has a rigid cast frame with ventilated spider and large vented pole piece. A low damping rubber surround assures decent midrange reproduction. A shorting ring is used in the motor to reduce intermodulation distortion and improve inductance symmetry.
