Magnetic Planar Speakers - Holographic 3D Imaging and Stunning Clarity

With a thin diaphragm suspended between two arrays magnets, they vibrate to produce sound waves. Planar magnetic speakers are renowned for their amazing clarity and 3D holographic images.

They are also suitable for a wide range of audio applications due to their low distortion, large horizontal and vertical dispersion, and low costs.

Superior Sound Quality

Planar magnetic speakers are known for reproducing detailed, clear sound with minimal distortion. This is due to the fact that they use an elongated diaphragm that has an electrically conductive trace that reacts to a magnetic field from magnets on one or both sides of the speaker. The diaphragm moves creating sound waves that can be transmitted through a dipole- or monopole-radiation pattern. This allows the diaphragm to move more evenly, and produce higher-quality sound than a typical dome or cone driver.

Planar magnetic drivers also have the benefit of a large and uniform sound dispersion. This allows for planar magnetic speakers the sound to be heard from any location in a room. Additionally, planar ribbon or dipole speakers offer an unnatural and expansive soundstage that has very little resonance. This creates an experience of listening that is hard to duplicate with other types speakers.

Planar magnetic speakers have a greater surface area than cone drivers and are more durable. They can also operate at higher volumes without creating excessive distortions or vibrations. They are also quieter than other types of speakers, making them an excellent choice for home theatre or HiFi applications.

Planar speakers are more expensive due to their intricate design. However, they offer superior audio quality and are worth the investment. In addition they have lower impedance than other types of loudspeakers, meaning they are easier for amplifiers to drive than conventional drivers.

Planar magnetic speakers are a great option for both professional and home use. However they aren't as popular in IEMs because they require more complex engineering to be able to fit into smaller forms such as headphones and earbuds. Recently, however there has been a rise in the availability of IEMs with planar magnetic technology. This includes the Rinko by Seeaudio and the S12 & Z12 by LETSHOUER, which have proven to offer an outstanding listenable experience.

Lower Distortion

For many audiophiles, the most sought-after feature of a speaker or headphone is low distortion. The distortion is caused in the speaker due to various factors, but perhaps the most popular cause of distortion is the voice coil inductance. When an alternating voltage is passed through the voice coil of the moving coil driver, the voice coil's inductance produces magnetic fields that cause the diaphragm to move. The movement or the excursion is what produces the sound wave, but it also creates unwanted resonances and harmonics that diminish the audio quality.

Magnetic planar speakers have a lower distortion than traditional dynamic drivers. This is because the "voice coil" has a larger surface area, instead of being squeezed into a tiny space within a huge piece of metal. This means that a well-designed planar magnet speaker can handle a lot more power than the traditional dynamic driver, without causing any audible strain.

Another way in which planar magnetic speakers can reduce distortion is by presenting an almost perfect resistive load to the amplifier in the system. The voice coil is an extremely thin, long wire that acts as an resistor. This makes the amplifier easy to operate and will always sound best when driving a magnetic planar speaker.

The high efficiency of magnetic planar speakers means that they generate less heat, even when playing a lot of music. This is important as the heat produced can damage the voice coil, reducing its lifespan and increasing distortion.

This doesn't mean that all single-ended planar magnetic speakers are distortion free. Because of their close magnet spacing, magnetic forces can interact and attract each other to a large extent, causing changes to the diaphragm's elasticity in the course of time. This issue is made more difficult by the close proximity of adjacent rows of magnets.

Better Heat Dissipation

In the last few decades, a variety of companies that specialize in HiFi audio headphones companies have created amazing masterpieces using planar magnet technology. Planar magnetic drivers offer impressive advantages over the common coil dynamics found in many headphones and speakers.

The "voice coil" can dissipate the heat more efficiently than a cone speaker as it is spread over an area that is larger. This lets the voice coil operate more linearly with less distortion and also permits a diaphragm that is light and can be driven at extremely high excursion levels.

This allows for the planar magnetic speaker to have exceptionally quick transient response, which means that sharp peaks and tiny details can be reproduced precisely even at extremely high SPLs. The sound that is produced is crystal clear without distortion and indistinguishable to the original source material.

The planar magnetic speaker also has a very flat impedance curve that ranges from approximately 4.2 Ohms in the bass, to 3.3 ohms in the Treble. This makes it a simple load to drive amplifiers, and similar to the resistive loads that electronics manufacturers to show their products' high-end quality.

A ribbon/planar diaphragm that is extremely light can move swiftly and without strain. This results in very clear and clean sound with a broad bandwidth and excellent linearity.

The ribbon/planar design is also extremely quiet, which helps to reduce distortion even further. It's also extremely stable across a wide range of temperatures, allowing the speaker to provide the same quality of sound for long periods of listening and also a large listening space.

While the benefits of a ribbon/planar speaker are numerous, it is crucial to remember that they are a specific type of loudspeaker and not appropriate for every application or for all listeners. A ribbon/planar that has a large radiating surface requires a large space to be able to deliver full-range sound with an acceptable SPL. For this reason, most such speakers are sold as tweeters or as an upper mid/high-range component of a two-way system.

Higher Power Handling

Magnetic planar drivers deliver clarity and detail that are not matched by cone drivers. They can show subtle details and reproduce complex sound precisely. They have a broad frequency response that allows them to produce a larger variety of frequencies with precision.

Planar speakers produce a directional sound, which can be a problem when you are listening to them along with others. However, it's what gives them their incredible dynamic range and stunning image. The sound is like a laser beam, shooting directly out of the speakers. It can be heard even when you are off-axis.

The flat diaphragm, combined with the front of the acoustic wave, gives them a greater perception of space and depth than cone speakers. They also tend to have an acoustic wavefront that is less noisy and are less distracting in noisy environments. Planar magnetic drivers are preferred by a large number of audiophiles because of their natural sound quality.

There are some limitations to the technology. Planar drivers are more difficult to create than conventional cone drivers, and they can be quite heavy, making them difficult to mount in certain environments. They also require a greater power output to drive them, which could limit their maximum output.

Wisdom Audio is a leader in the development of PMD technology, and its products continue to push the boundaries of what this revolutionary technology can accomplish. Its new patented material can withstand temperatures much higher than PET which is the main ingredient in planar drivers. Its unique design also reduces the effects of diffraction, which can be caused by sound waves traveling through narrow gaps and curves.

In the end, its speakers and headphones are known to deliver an exceptionally detailed and clear sound that's free of distortion. They're also more responsive than traditional cone drivers which helps increase their bass response. They're also capable of reproducing high frequencies with incredible accuracy and produce deep, powerful bass.
