20 Fun Details About Planar Magnetic Speakers
Planar Magnetic Speakers

Planar magnetic speakers use a flat diaphragm to convert an electrical signal into sound. They are well-known for their clarity and accuracy as well as their low distortion. They offer a broad range of frequencies, making them easy to hear.

The diaphragms in dynamic drivers are significantly heavier and stiffer than the ones used in planar magnet speakers. This hinders their ability for them to move and accelerate quickly and can cause distortion in the sound.

They are simple to construct.

Many people believe that building planar magnet speakers is difficult. However, they are very simple to construct. It is crucial to follow the instructions carefully and build a speaker that is well-engineered. The result will be a high-quality audio system that can compete with any available model. Planar magnetic speakers are simple to build and provide superior sound quality compared to traditional dynamic drivers. They provide superior detail, extended dynamic range, and a controlled level of directivity, which all contribute to a full listening experience.

Unlike conventional loudspeakers, which project sound in circular wave fronts they emit flat waves that are directed. This enables them to reproduce sounds at very low frequencies, which would be difficult for standard speakers to do. In addition, their incredibly precise image can bring the music to life in a way that makes conventional speakers sound slow in comparison.

A planar magnetic drive produces an audio sound using a thin sheet of metal suspended between two stationary conductive plates. The audio signal transmits an electric current to the panel, which rapidly shifts between negatives and positives. The magnetic array is able to move the panel's negative end in a circular motion and causes the diaphragm of the panel to move. The result is an excellent dynamic response, and a broad soundfield with minimal distortion.

The maximum distance of an acoustic speaker is one of the most important aspects in its performance. It is the maximum distance that a speaker can travel before it begins to distort. It is typically measured at a specific frequency and at a given output level. If you'd like to hear the 20-Hz bass, you'll require an audio system that has an excursion of around 1 millimeter.


A reliable planar magnetic driver must be able to handle high excursion while maintaining its structural integrity. It should also be able effectively disperse heat and manage a lot of power. To fulfill these goals the speaker's voice coil must be with sufficient thickness and size. The voice coil should be wrapped in a material that is capable of conducting electricity.

They dissipate heat effectively

This is a very important aspect of any speaker. The voicecoil is in close proximity to the magnet array and has a high flux density across the gap. This is the cause of heat in a speaker and it must be dissipated to avoid damage and distortion. The voicecoil has two methods to get rid of heat: convection and radiation. Radiation is the preferred method since it doesn't have the pumping effect of the cone's movement, however, it must be executed with care and the design has to be capable of handling the force that is being applied.

The first step is to ensure that the gap between your voicecoil array and array is at least 1 millimeter. This is critical, as the gap can cause pretty horrible distortion if it's greater than this. The gap should also be large enough to allow the voicecoil's movement to avoid hitting the rearplate. For this reason, the wide gap designs favoured by many manufacturers are inefficient and will only work well at low frequencies.

Place a magnet on the gap, and measure the resistance. The higher the resistance the less heat will be dissipated and the higher the chance of distortion. The lower the resistance is, the more efficient the speaker will be, and the less distortion it will cause.

Planar magnetic speakers are able to reproduce the upper octaves with amazing accuracy, but they aren't able to reproduce the lower frequencies since they require a large diaphragm. Many planar magnetic speakers combine the woofer and a tweeter. This allows them to be able to cover a larger frequency range with less distortion.

Planar magnetic drivers are known for their low distortion and excellent bass. This is due to the fact that they are dipoles which means they radiate the same energy forward and back with inverted phase. This is a significant advantage over conventional drivers that are subject to mechanical distortion and strong Q resonances.

They can handle a lot of power

Many people are worried that planar magnetic speakers will not be able to handle the amount of power that they require however the reality is that they do. The "voice coil" has a greater surface area than a dynamic driver, and can therefore dissipate more heat. Furthermore the diaphragm itself is thin and light, which helps to reduce distortion levels.

However, it's important to keep in mind that an acoustic speaker planar will still need to be driven by a large amount of power in order to provide high-quality sound. They're not able to efficiently disperse energy like a conventional speaker, which means that they can be sensitive to how the room is set up. They also have directional characteristics which means that if you listen from just a few degrees away, the sound level will be reduced.

Inefficiency is another aspect that allows them to handle large amounts of power. They have a lower impedance, so they require more power to reach the same amount. Additionally, they are prone to magnetic saturation, which could cause distortion.

Measuring the maximum excursion of a planar magnetic speaker is an excellent way to test its ability to withstand high-power. This is the amount of distance the diaphragm is able to travel before it hits the magnet array and begins to distort. The most powerful planar speakers can achieve a maximum distance of 1 mm.

Planar magnetic speakers also have a greater range of frequencies than cone drivers. This is beneficial in certain circumstances. They can reproduce a higher number of frequencies, which can enhance the quality of music and sound effects. This can help to make it easier to distinguish between the different instruments and vocals that are part of a song.

The top planar magnetic speakers can reproduce a wide range of frequencies, including the bass frequencies. This is an excellent benefit for those who wish to listen to music in various environments. These speakers are more expensive than traditional speakers, but offer a distinct immersive experience. They are also a good option for home theater systems.

The direction of the arrow is crucial.

When an electrical signal is applied to the conductive trace pattern the magnetic field causes a diaphragm movement that generates sound waves. The movement is more precise and controlled than traditional cone drivers, allowing for a larger frequency response. This allows planar speakers to produce more detail and clarity in the music.

These diaphragms with flat sides can be designed to be either dipole (radiating equally in front and back like electrostatics and Maggies) or Monopole (radiating only in the direction of forward, more like conventional dynamic speakers). This flexibility lets designers choose from a variety of options when designing wall or built-in loudspeakers. They can provide high-quality performance at an affordable price.

The diaphragm in a planar magnetic driver is generally made from an ultra-thin, light polymer that is coated with a circuit made of copper that can conduct electricity. The diaphragm with a metal-laced coating is surrounded by arrays of magnets in wide-spaced bars. The magnetic bars create an extremely strong magnetic field that can draw and disperse air particles within the diaphragm. The magnetic fields also aid to radiate heat away from the speaker without causing any strain to the voice coil.

Planar magnetic speakers are more sensitive than cone speakers and can handle a lot of power without overheating. Going Listed here have a low impedance, which means they require less amplification in order to maintain the same sound level. They are able to reproduce the entire spectrum of audio frequency including highs and bass. They are often augmented with boxed woofers that can reproduce low frequencies with greater accuracy.

One drawback of single-ended magnetic loudspeakers is that they have poor damping. This can cause high-Q resonances in the low frequency spectrum of the speaker's response, which may color the sound. The solution to this issue is a hybrid design which combines the advantages of dipole and planar technology.

One of the most important elements that determine the performance of a planar magnetic speaker is the correct placement in the room. Many aspects of sound are affected by this, including the bass response, imaging and the soundstage's depth and width. It is essential to avoid toe-ins, as it can negatively impact the mid-range and highs. The speaker should be placed where the central image is narrowest.
