This Most Common Planar Magnetic Speakers Debate Doesn't Have To Be As Black And White As You Think
Planar Magnetic Speakers

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

The diaphragms in dynamic drivers are much stiffer and heavier than those used in planar magnetic speakers. This hinders their ability to accelerate and move quickly which can result in distortion of sound.

They are simple to construct

Many people think that building planar magnetic speakers is a difficult task, but they are extremely simple to construct. The trick is to follow the directions and build a high-quality speaker. The result will be an excellent audio system that can compete with any model that is commercially available. Apart from being simple to construct, planar magnetic speakers also offer better sound quality than traditional dynamic drivers. They provide superior clarity as well as a larger dynamic range, and a more controlled directivity that all make for a more immersive listening experience.

Contrary to conventional loudspeakers, which emit sound in circular fronts, planar magnetic speakers emit flat waves that are directional. They can reproduce low-frequency sounds which is not possible with conventional speakers. Additionally, their precise imaging can bring music to life in a manner that makes traditional speakers sound sluggish in comparison.

To produce a sound, a planar magnetic driver utilizes a thin film of metal suspended between two stationary conductive panels. The audio signal is carried by a current through the panel, which quickly shifts between positive and negative. The magnetic array is able to move the panel's negative end back and forth, causing the diaphragm to move. The result is a large sound field that has minimal distortion and an excellent dynamic response.

The maximum excursion of a planar magnet speaker is one of the most important aspects in its performance. It is the maximum distance a speaker can travel before it starts to distort. This is measured at a particular frequency and output level. If you'd like to hear the 20-Hz bass, then you'll need a speaker that has an excursion of around 1 millimeter.

A solid planar magnet driver must be able to keep the integrity of its structure while experiencing high excursion. It must be able to disperse heat effectively and handle a large amount of power. The voice coil of the speaker must be large and thick enough to satisfy these specifications. The voice coil must also be wrapped in a material that can conduct electricity.

They dissipate the heat effectively

This is an essential aspect of any speaker. The voicecoil is extremely close to the magnet array and has a high flux density in the gap. The voicecoil generates heat. voicecoil and must be dissipated to avoid distortion and damage. Convection and radiation are the two ways that the voicecoil can be rid of heat. Radiation is the preferred method since it does not have the pumping effect of the cone movement, but it must be done carefully and the design must be capable of handling the power being applied.

The first step is to make sure that the distance between the array and the voicecoil is at a minimum of 1 millimeter. This is crucial, since the gap could cause very unpleasant distortion if greater than this. The gap must also be large enough to permit the voicecoil to move without hitting the rearplate. The wide gap designs that are popular among manufacturers aren't efficient and only work at low frequencies.

An effective method to test the gap is to put a magnet on the gap and test the resistance between the magnet and the voicecoil. The greater the resistance, the less heat is dissipated and the more likely it will distort. The lower the resistance, the more efficient the speaker will be, and the less distortion it will produce.

Planar magnetic speakers are able to reproduce the upper octaves very accurately, but cannot reproduce lower frequencies due to the huge diaphragm required. Many planar magnetic speakers combine an woofer and a tweeter. This lets them provide a wider frequency range and have less distortion.


In addition to their excellent bass, planar magnetic drivers have a very low distortion. This is due to the fact that they are dipoles which means that they emit equal energy front and back, with an inverted phase. This is an advantage over conventional drivers that can be subject to mechanical distortion and strong Q resonances.

They can handle lots of power

The reality is that planar magnetic speakers are able to handle the power they need. This is due to the fact that the "voice coil" is spread across more space than it would be in a conventional dynamic driver, which means that it can dissipate heat more efficiently. The diaphragm is thin and light, helps to reduce distortion.

It is important to keep in mind that a planar magnetic speaker still requires a lot power to produce a good sound. They aren't able to disperse energy like a traditional speaker, so they are sensitive to the way the room is installed. They are also directional which means that if you listen from just a few degrees away, the volume is likely to be diminished.

Another factor that affects their ability to handle a lot of power is the fact that they are inefficient. This is due to an impedance that is lower than conventional drivers, meaning they require more power to achieve the same volume of listening. Furthermore, they are susceptible to magnetic saturation, which can cause them to distort.

A great way to determine the capability of a planar magnetic speaker to take on a lot of power is to determine its maximum excursion. This is the length the diaphragm is able to travel before it comes into contact with the magnet array and begins to distort. The most powerful planar speakers can reach a maximum distance of 1 mm.

Planar magnetic speakers also offer a greater range of frequencies than cone drivers. This is beneficial in certain circumstances. They can reproduce a greater quantity of frequencies, which could improve the quality of sound and music. This makes it easier to distinguish between vocals and instruments in a song.

The most effective planar magnetic speakers can reproduce a wide range of frequencies, which includes the bass frequencies. This is a huge benefit for those who want to enjoy music in a variety of settings. They can be more expensive than standard loudspeakers, yet they provide an experience that is unique and immersive. These speakers are also suitable for home theater systems.

They are directional

When an electrical signal is positioned on the conductive trace patterns the magnetic field creates the diaphragm to move, which produces sound waves. The movement is more precise and controlled as compared to conventional cone drivers. This enables more frequency response. headphonesshop.uk lets planar speakers reproduce more clarity and detail the music.

These diaphragms with flat sides are available in two different designs: dipole (radiating in both directions, like electrostatics and Maggies) or Monopole (radiating in just one direction, more like traditional dynamic speakers). This flexibility offers designers the possibility of a variety of options for on-wall or in-wall loudspeakers which can deliver exceptional performance at affordable cost.

The diaphragm of a planar magnetic driver is typically made from a light, thin polymer, coated with a copper circuit that can conduct electricity. The diaphragm with a metal-laced coating is surrounded by an array of magnets that are arranged in bars with a wide spacing. The magnetic bars create an extremely strong magnetic field that can draw and disperse air particles within the diaphragm. The magnetic fields can also help to disperse heat away from the speaker, without causing audible strain on the voice coil.

Planar magnetic speakers are more sensitive than cone speakers and can handle a lot of power without overheating. They also have a low impedance that means they require less amplification in order to achieve the same listening quality. They are able to reproduce the entire spectrum of audio frequency including highs and bass. They are typically augmented with woofers boxed to reproduce low frequencies with greater precision.

One of the drawbacks of single-ended planar magnetic loudspeakers is their relatively poor damping. This can cause high-Q resonances in the low frequency of the speaker's response, which can cause coloration of the sound. This issue can be resolved through a hybrid design that blends the advantages of planar and dipole technology.

One of the most crucial factors for the success of a planar magnetic speaker is the correct placement in the room. A variety of aspects of sound are affected by this, including the bass response, imaging and the soundstage's depth and width. It is crucial to avoid toe-ins, as it can negatively impact the mid-range and highs. The speaker should ideally be placed in the area where the central image is narrowest.
