15 Things You Didn't Know About Planar Magnetic Driver
The Benefits of a Planar Magnetic Driver

Planar magnetic drivers are used in the best headphones and IEMs. It has numerous advantages that make it distinct from other balanced or dynamic armature drivers.

It is important to be aware of the disadvantages of planar drivers. They are a higher price and requirement for an amplifier to drive them.

Ultra-thin diaphragms

Every sound we hear, from the loudest sound of a cymbal crash to the most subtle creak of the piano bench is portrayed by a complex and turbulent pressure wave. The driver of a top headphone has to reproduce these waves accurately, without losing any detail or distortion. This requires a light, thin diaphragm that can be responsive and move quickly to a wide range of frequencies.

Planar magnetic drivers employ a flat diaphragm that is coated with a conductive coating and floats between magnets. This allows them to create a uniform magnetic field over the entire surface of the diaphragm, thereby reducing distortion.

This approach, however introduces additional challenges such as the possibility of membrane resonance issues and turbulent airflow inside the grid-like magnetic arrays. These issues could result in an amplitude of the mechanical resonance frequency of the diaphragm that is several times higher than input frequency, reducing the sensitivity of voice pressure sensor.

Utilizing a patent-pending technology called 'Spherical Acoustic Structure' (SAS), Final was successful in overcoming these limitations with the D8000 by making use of a single piece material that is both diaphragm and conductor. This solution was based on ribbon speakers with their spherical conducting, but it was cheaper for headphones because of its size and power requirements.

Another challenge common to many plansar magnetic designs is a ringing effect that is seen on high-frequency and low-frequency bass notes. This is due to a mismatch with the force of the magnet that is applied to the diaphragm as compared to the natural flexing of the diaphragm.

Final used a thin polymer film dubbed Parylene to solve this problem. This material was chosen due to its superior mechanical strength, bendability and uniform thickness. It also has thickness consistency. These qualities were essential to ensure that a rigid, thin film would stretch without creating unwanted wrinkles or wrinkles.

Superior transient response

The method by which planar magnetic drivers generate sound waves is different from traditional dynamic drivers. The primary difference is that the conductor of a planar driver is laid out in a flat 2D pattern on the diaphragm, instead of the coil being wrapped around the diaphragm in a cone. This allows the conductor to react to magnetic fields on both sides of the diaphragm, and produce sound waves with high accuracy. This technology eliminates the need for voice coils that can change their impedance based on frequency, which results in distortion-free music.

Planar magnetic drivers are lighter and more durable than conventional drivers because they don't contain moving parts that wear out over time. They are also less prone to distortion caused by harmonics, which can cause degradation in the audio quality. They also have a quicker response time and can reproduce transient sounds with greater speed.

The vast surface area of the diaphragm planar, however it requires more power in order to move it and generate sound waves. Therefore, these headphones require an amplifier to be able to drive them at a sufficient level. Some listeners might not be interested in the extra weight and expense.

Planar magnetic drivers also provide larger soundstages than dynamic headphones, making them more spacious. This is because the huge diaphragm is able to move more evenly to create the planar sound wavefront rather than a focused circular wavefront typical of dynamic drivers. This is a major characteristic of headphones that planar and provides an immersive listening experience.

Audio reproduction that is natural and faithful

Planar magnetic drivers deliver natural and faithful audio reproduction as contrasted to traditional dynamic driver models. Unlike conventional dynamic drivers that have a cone-shaped diaphragm that vibrates back and forth, planar magnetic drivers use two rows of magnets in order to generate equal magnetic force on the diaphragm. This results in the diaphragm moving in a wave-like movement which prevents distortion. They also have the ability to reproduce music with a wider frequency range, ranging from the lowest lows to the highest highs, making them an ideal choice for music lovers as well as audio professionals.

The diaphragm is thin and flexible. in a planar magnetic driver moves faster than an active driver. This allows it to respond to changes in the sound signal and create accurate reproduction. The lack of a coil in the diaphragm is also a deterrent to the possibility that mechanical parts will meet up with each and cause distortions at higher volume.

The diaphragm is able to easily displace large volumes air to reproduce bass frequencies. The size of the diaphragm and its flexibility are essential for producing the rich bass that you hear in your music. Dynamic drivers, on the other hand, tend to be small and stiff, making it difficult for them to endure the high-speed movements required to reproduce bass.

Despite their benefits they are not used as much in headphone or IEM products due to the high cost and the complexity of their design. Partly, this is due to the fact that they require amplifiers to be driven. This makes them less portable. They are still popular with music enthusiasts and critics who appreciate their high audio quality and exceptional performance.

Wide frequency response

Planar magnetic headphones employ flat and uniform diaphragms to produce sound in a measured and even manner. This produces a wide frequency response that provides accurate and faithful reproduction of music. They are also known for their outstanding transient response, meaning they are able to react quickly to audio signals and reproduce them as accurately as possible.


They accomplish this by using a planar array consisting of conductors spread across a thin, diaphragm that is sandwiched between two magnets. When an electrical signal passes through this conductor array it is transformed into electromagnetic and interacts with diaphragm magnetic fields to produce the push/pull effect. This lets the diaphragm respond quickly to audio input, producing top-quality music reproduction with incredible quality and precision.

check out here that makes these headphones so loved by audiophiles is their low distortion rate. They aren't able to produce the same amount of harmonic distortion since they don't have the same moving components. In addition, they have lower impedances than their counterparts, and offer a pure resistive load to amplifiers, which makes them easier to drive using a greater amount of power.

Planar magnetic drivers are utilized in high-end audio equipment because of their superior performance. This makes them more expensive and require an amplifier to work and are therefore not suitable for a grab-and-go driver. Nevertheless, audiophiles are willing to sacrifice the extra expense and effort in exchange for the high-quality that these headphones can offer. They are regarded as a top option for those looking for the best listening experience.

Low distortion

The diaphragm in a planar magnetic driver is very thin, which means that it can move at high speeds without losing control or breaking. This gives a great transient response. This means that the driver is able to respond to abrupt changes in audio signals quickly and accurately. This allows you to listen to the details of music and make them sound more natural and real.

Planar magnetic drivers also have the advantage of producing the same amount of force throughout the diaphragm, which prevents distortions when the volume is increased. This is one of the main reasons why planar magnetic headphones sound so good - dynamic drivers use thicker and heavier diaphragms that aren't capable of moving as quickly or with the same acceleration. In fact, they could fail if the forces are too strong or exceed the limits of their structural integrity, causing various points on the diaphragm to begin moving out of sync.

Planar magnetic drivers on the other hand produce an extremely powerful electromagnetic force that is directly applied to the diaphragm. This eliminates the need for a voice coil which is required in the majority of headphones with traditional dynamic cone drivers. This helps to achieve greater dynamics, a larger soundstage and an exceptional bass response.

Because of these benefits they are widely considered to be the best type of headphone driver for audiophiles. While they do have some issues like power requirements and cost but their capability to provide superior sound quality makes them a great option for those looking for the highest quality in audio reproduction. These drivers offer superior clarity and detail at all frequencies, except for low bass. Dynamic drivers are still preferred.
