11 "Faux Pas" That Are Actually Okay To Make With Your Planar Magnetic Speakers

Planar Magnetic Speakers

Planar magnetic speakers use an elongated diaphragm to transform an electrical signal into sound. They are renowned for their accuracy, detail and low distortion. They also have a broad frequency response, making them easy to listen to.

Dynamic drivers have more robust and rigid diaphragms than thin and ultra-light ones used in planar magnetic speakers. This makes it difficult for them to move and accelerate quickly which can result in distortion of sound.


These are easy to construct

Many people believe that building planar magnet speakers is difficult. However, they are very simple to build. The key is to follow the directions and construct a well-engineered speaker. The result will be a sound system of superior quality that can compete with any model that is available commercially. Planar magnetic speakers are easy to construct and provide superior sound quality compared to traditional dynamic drivers. They provide superior clarity, a wider dynamic range and controlled direction that all contribute to a more immersive listening experience.

Unlike conventional loudspeakers, which emit sound in circular fronts Planar magnetic speakers emit flat waves that are highly directed. This enables them to reproduce sounds at extremely low frequencies, which can be difficult for conventional speakers to do. Their extremely precise image brings the music to life, making standard speakers sound sluggish by comparison.

To create a sound wave, a planar magnetic driver makes use of a thin metal film suspended between two stationary conductive panels. The audio signal is carried by a current through the panel, and it quickly shifts between positive and negative. The magnetic array moves the panel's negative end forward and back, causing the diaphragm to move. The result is a wide sound field with minimal distortion and excellent dynamic response.

One of the most important elements in a planar magnet speaker's performance is its maximum excursion, which is how the speaker's movement can be measured before it begins to distort. This is measured at a specific frequency and output level. For instance, if would like to hear a 20 Hz bass note, you will require a speaker that has an excursion limit of approximately 1 millimeter.

A good planar magnetic driver must be able to endure high excursion, while retaining its structural integrity. It must be able to disperse heat efficiently and handle a large amount of power. To fulfill these requirements, the speaker's voice coil must be sufficiently thick and wide. The voice coil must also be wrapped in a conductive material that is capable of conducting electricity.

They effectively disperse heat

This is a crucial aspect of any speaker. The voicecoil is in close proximity to the magnet array and has a very high flux density across the gap. This is the reason for heat in a speaker, and it must be dissipated to prevent distortion and damage. The voicecoil has two ways to eliminate heat - convection and radiation. Radiation is the preferred option since it doesn't have the pumping effect of the cone's movement however, it must be executed carefully and the design must be able to handle the power that is being applied.

The first step is to ensure that the gap between your voicecoil array and the array is at least 1 millimeter. This is important, as gaps that are larger than 1mm can result in severe distortion. The gap should also be large enough to allow the voicecoil's movement without hitting the rearplate. This is why the wide gap designs that are favored by many manufacturers are inefficient and will only work well at low frequencies.

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

Planar magnetic speakers reproduce the upper octaves very precisely, but they are unable to reproduce lower frequencies due to the huge diaphragm needed. A lot of planar magnetic speakers incorporate a woofer with a tweeter. This lets them be able to cover a larger frequency range and have less distortion.

Planar magnetic drivers are known for their low distortion and excellent bass. This is due to the fact that they are dipoles, meaning that they radiate equal energy front and back using inverted phase. This is a huge advantage over traditional drivers, which can be subject to strong Q resonances and mechanical distortion.

They can handle a great deal of power

The reality is that planar magnetic speakers are able to provide the power they require. This is due to the fact that the "voice coil" is spread out over a larger area than in a traditional dynamic driver, which means that it is able to disperse heat more effectively. The diaphragm, which is small and light, also helps to reduce distortion.

It's important to keep in mind that a planar magnetic speaker will still require a lot power to produce a good sound. They can't easily disperse energy like a conventional speaker, which means that they can be sensitive to how the room is set up. Additionally, they're directional, which means that listening from a few degrees off-axis can result in the perceived sound level dropping significantly.

Another reason for their capacity to handle a large amount of power is the fact that they are not efficient. This is because they have less impedance than standard drivers, which means they need more power to achieve the same listening volume. Furthermore, they are susceptible to magnetic saturation, which can cause them to distort.

The measurement of the maximum excursion of a planar magnetic speaker is a great way to test its capacity to handle high-power. This is the length the diaphragm can move before it comes into contact with the magnet array and begins to distort. The most powerful planar magnetic speakers can reach an approximate distance of 1 mm before this occurs.

Planar magnetic speakers may also offer a higher frequency response than traditional cone drivers, which can be a benefit in some circumstances. They can produce higher frequencies, which can enhance the quality of music. This can make it easier to distinguish between the instruments and vocals in the song.

The best planar magnetic speakers can reproduce a wide spectrum of frequencies, including the bass frequencies. This is a huge benefit for people who wish to listen to music in a variety environments. These speakers are more expensive than traditional loudspeakers, yet they provide an immersive and unique experience. These speakers are also great for home theater systems.

The direction of the arrow is important

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

These flat diaphragms are available in two designs: dipole (radiating in both directions, like electrostatics and Maggies) or Monopole (radiating in just one direction, similar to traditional dynamic speakers). This flexibility allows designers to choose from a variety of options when designing wall or built-in loudspeakers. They can offer outstanding performance at a reasonable price.

The diaphragm in a planar magnet driver is typically constructed of a thin, light polymer that is coated with a copper circuit that can conduct electricity. The diaphragm that is coated with metal is surrounded by a variety of magnets in wide-spaced bars. These bars create a powerful magnetic field which can draw and disperse air particles within the diaphragm. The magnetic fields also help to radiate heat away from the speaker without causing audible strain on the voice coil.

Planar magnetic speakers have higher sensitivities than conventional cone speakers, and they can handle a large amount of power without overheating. They also have a low impedance which means they require less amplification to reach the same listening level. They can reproduce the full range of audio frequencies, including bass and highs. They are often augmented with woofers boxed to reproduce low frequencies with greater accuracy.

The relatively poor damping of single-ended planar magnet loudspeakers is a disadvantage. This can result in high-Q resonances in the low frequency spectrum of the speaker's response, which can color the sound. The solution is a hybrid design which combines the advantages of dipole and planar technologies.

One of the most crucial factors for the success of a planar magnetic speaker is proper placement in the room. This impacts a variety of characteristics of sound, including bass response imaging, soundstage width and breadth. Toe-in can negatively affect the midrange and the higher frequencies. The ideal speaker will be placed in the area where the central image is at its narrowest.
