An EMF (Electro-Motive Force) subwoofer, also known as a planar magnetic subwoofer, is a unique type of subwoofer that uses planar magnetic technology to generate sound. Unlike traditional subwoofers that use a voice coil to move a cone, EMF subwoofers use a flat diaphragm suspended between two magnets. When an electrical signal is passed through the diaphragm, it creates a magnetic field that interacts with the magnets, causing the diaphragm to vibrate and produce sound.
EMF subwoofers are known for their exceptional accuracy, low distortion, and extended frequency response. They are often used in high-end audio systems and professional recording studios where precise sound reproduction is critical. However, EMF subwoofers can be more expensive than traditional subwoofers and require more power to operate.
In this article, we will take a closer look at EMF subwoofers, including their design, advantages, and disadvantages. We will also provide some tips on how to choose the right EMF subwoofer for your needs.

Low distortion
EMF subwoofers are also known for their low distortion. This is due to their unique design, which uses a flat diaphragm suspended between two magnets. When an electrical signal is passed through the diaphragm, it creates a magnetic field that interacts with the magnets, causing the diaphragm to vibrate and produce sound.
- Linear excursion
EMF subwoofers have a very linear excursion, which means that the diaphragm moves in a straight line without any distortion. This is in contrast to traditional subwoofers, which can have a non-linear excursion, which can introduce distortion.
- Symmetrical magnetic field
EMF subwoofers also have a symmetrical magnetic field, which means that the magnetic field is evenly distributed around the diaphragm. This helps to reduce distortion and improve sound quality.
- No moving parts
Unlike traditional subwoofers that use a voice coil to move a cone, EMF subwoofers do not have any moving parts that can introduce distortion. This results in a cleaner, more accurate sound with less distortion.
- High power handling
EMF subwoofers can handle high power without distorting, which makes them ideal for use in high-volume applications.
Overall, EMF subwoofers offer the lowest distortion of any type of subwoofer. They are ideal for use in high-end audio systems and professional recording studios where precise sound reproduction is critical.
Extended frequency response
EMF subwoofers also have an extended frequency response, which means that they can reproduce a wider range of frequencies than traditional subwoofers. This is due to their unique design, which uses a flat diaphragm suspended between two magnets. When an electrical signal is passed through the diaphragm, it creates a magnetic field that interacts with the magnets, causing the diaphragm to vibrate and produce sound.
- Lower bass extension
EMF subwoofers can reproduce lower bass frequencies than traditional subwoofers. This is because the flat diaphragm is more efficient at moving air than the cone in a traditional subwoofer.
- Higher treble extension
EMF subwoofers can also reproduce higher treble frequencies than traditional subwoofers. This is because the flat diaphragm is lighter and more responsive than the cone in a traditional subwoofer.
- Flat frequency response
EMF subwoofers have a very flat frequency response, which means that they reproduce all frequencies evenly. This is in contrast to traditional subwoofers, which can have a boosted bass response or a rolled-off treble response.
- Wide bandwidth
EMF subwoofers have a wide bandwidth, which means that they can reproduce a wide range of frequencies without any significant loss of sound quality.
Overall, EMF subwoofers offer the most extended frequency response of any type of subwoofer. They are ideal for use in high-end audio systems and professional recording studios where precise sound reproduction is critical.
Expensive
EMF subwoofers are more expensive than traditional subwoofers. This is due to their unique design and the high-quality materials that are used in their construction.
- Planar magnetic technology
The planar magnetic technology used in EMF subwoofers is more expensive to manufacture than the voice coil technology used in traditional subwoofers.
- High-quality materials
EMF subwoofers are made with high-quality materials, such as aluminum and carbon fiber. These materials are more expensive than the materials used in traditional subwoofers.
- Limited production
EMF subwoofers are not as common as traditional subwoofers, so they are more expensive to produce.
- High demand
EMF subwoofers are in high demand, which also contributes to their high price.
Overall, EMF subwoofers are more expensive than traditional subwoofers. However, they offer superior sound quality and performance, which makes them a good investment for audiophiles and professionals who demand the best possible sound reproduction.
Require more power to operate
EMF subwoofers require more power to operate than traditional subwoofers. This is because the planar magnetic technology used in EMF subwoofers is less efficient than the voice coil technology used in traditional subwoofers.
The efficiency of a subwoofer is measured in decibels per watt (dB/W). A higher dB/W rating means that the subwoofer can produce more sound output for a given amount of power input. EMF subwoofers typically have a dB/W rating of around 85-90 dB, while traditional subwoofers can have a dB/W rating of around 95-100 dB.
This means that an EMF subwoofer will require more power to produce the same amount of sound output as a traditional subwoofer. For example, if an EMF subwoofer has a dB/W rating of 85 dB and a traditional subwoofer has a dB/W rating of 95 dB, then the EMF subwoofer will require twice as much power as the traditional subwoofer to produce the same amount of sound output.
The amount of power that an EMF subwoofer requires will depend on the size of the subwoofer and the desired sound output level. For example, a small EMF subwoofer with a 10-inch driver will require less power than a large EMF subwoofer with a 15-inch driver. Additionally, an EMF subwoofer that is used in a home theater system will require less power than an EMF subwoofer that is used in a professional recording studio.
Overall, EMF subwoofers require more power to operate than traditional subwoofers. However, they offer superior sound quality and performance, which makes them a good investment for audiophiles and professionals who demand the best possible sound reproduction.
