What Is Woofer?
Woofer or bass speaker is a technical term for a loudspeaker driver designed to produce low frequency sounds, typically from 50 Hz up to 1000 Hz. The name is from the onomatopoeic English word for a dog’s bark, “woof” (in contrast to the name used for loudspeakers 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 loudspeaker 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.
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. Since the 1990s, a type of woofer (termed subwoofer), which is designed for very low frequencies only, has come to be commonly used in home theater systems and PA systems to augment the bass response; they usually handle the very lowest two or three octaves (i.e., from as low as 20 to 80 or 120 Hz).
What Is Woofer Speaker Made Of?
Nowadays, the most common materials used in woofers are aluminum, paper pulp, or polypropylene foam. Their unique properties allow efficient reproduction of low-frequency sounds without adding heavy weight on top of your cabinet, making it difficult to transport these speakers around.
What Is A Woofer Used For?
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.
How Do You Use A Woofer Speaker?
Using a subwoofer cable (RCA cable), connect the subwoofer to the AV receiver by running the cable from the receiver’s subwoofer output to the subwoofer’s line input. Klipsch subwoofers can be connected via the LFE channel, the white RCA connection, or in a stereo pair by using both the white and red RCA connections.
How Many Watts Is A Woofer?
Any subwoofer with a wattage of 150-500 is best suited for a great music listening experience and is easy on the pocket. A subwoofer can be connected through wired or wireless connectivity. A wired system would be connected to speakers from where it draws the audio.
Does Woofer Make Noise?
Subwoofer hum or buzz is a low-level noise that can be present whenever a passive or powered subwoofer is turned on, whether or not it is playing. This 60-hertz hum is a result of being plugged into an AC wall outlet. Sometimes the hum is noticeable; sometimes, it takes some focused listening to notice.
How Can You Make Your Woofer More Louder?
- Position Your Subwoofers Properly.
- Properly Tune The Subwoofer.
- Adjust Crossover & Phase Setting.
- Use High-Quality Files.
- Minimize Electrical Impedance.
- Include Sound Dampening Resources.
- Change the Cables.
- Isolate The Subwoofer From Your Floor.
How Do You choose A Woofer Speaker?
The internal amplifier is the beating heart of your subwoofer and the most important thing it does is power the speaker driver. That power is measured in watts and understanding it is the key to choosing a good sub. Subwoofers usually have two types of wattage listed on their specs: RMS and Peak.
Where Should You Place Your Woofer?
Subwoofer placement in the front of the room is the most common and usually results in the best blending with the main speakers and center channel and minimizes localization effects.
How Long Does A Woofer Last?
The life expectancy of a subwoofer is seven to 12 years, depending on how well they are taken care of. Some high-quality subwoofers can last up to 20 years without any decrease in sound quality or bass frequencies.
