Magnetic Planar Speakers - Holographic 3D Imaging and Stunning Clarity
Utilizing a diaphragm that is thinly tensioned suspended between two arrays of magnets, they vibrate to produce sound waves. Planar magnetic speakers are renowned for their holographic 3D imaging and incredible clarity.
They are also ideal for a variety of audio applications because of their low distortion, broad vertical and horizontal dispersion and cost-effective prices.
Superior Sound Quality
When it is about high-performance audio, planar magnetic speakers are known for their ability to reproduce clear, detailed sound with low distortion. This is because they utilize flat diaphragms with a conductive trace pattern that reacts to magnetic fields emanating from magnets on either or both sides of the speaker. The diaphragm rotates and causes sound waves to be transmitted via the dipole-radiation pattern. This makes the diaphragm move more evenly and produce an improved sound quality than the typical cone or dome driver.
Planar magnetic drivers also have the benefit of a broad, uniform sound dispersion. This allows the sound to be heard from any position within a room. Planar dipoles or ribbon speakers also offer an incredibly spacious and natural soundstage that has very little resonance. This results in an immersive listening experience that brings the music to life in a manner that is difficult to duplicate with other types of speakers.
Because they cover a large surface area, planar magnetic speakers are also more durable than conventional cone drivers. They can operate at higher volumes without causing excessive vibration or distortion. They are also quieter than other kinds of speakers, which makes them a great option for home theatre and HiFi applications.
Planar speakers are more expensive due to their complex design. However, they offer superior audio quality and are worth the investment. In addition, planar speakers have lower impedance than other types of loudspeakers, meaning they are less difficult for amplifiers to drive than traditional drivers.
While these advantages make planar magnetic speakers an excellent option for both professional and home applications, they are less popular in IEMs because they require more sophisticated engineering to integrate into small form factors such as headphones and earbuds. Recently, however there has been a rise in the variety of IEMs that feature planar magnetic technology. The Rinko by Seeaudio and the S12 and Z12 from LETSHOUER are just two examples of IEMs that have been proven to provide a great listening experience.
Lower Distortion
For a lot of audiophiles, the most desired characteristic of a speaker or headphone is its low distortion. Inductance in the voice coil is the main reason for distortion in speakers. When an alternation voltage is applied to the voice coil of the moving coil driver, the inductance of the voice coil creates a magnetic field that causes the diaphragm to move. The resultant movement, or excursion is what causes the sound to be created but it also generates unwanted harmonics and resonances which affect the audio quality of the speaker.
One of the main advantages of magnetic planar speakers is that they have much less distortion than traditional drivers. This is due to the fact that the "voice coil" has an increased surface area instead of being squeezed into a small space within a massive piece of metal. A well-designed planar magnet speaker can withstand more power than a dynamic driver, but without any audible strain.
Another way that planar magnetic speakers reduce distortion is to provide an almost perfect resistive load to the amplifier inside the system. The voice coil is an extremely thin, long wire that acts as resistor. This makes it easy for the amplifier to drive and it always sounds its best when driving a planar magnetic speaker.
The high efficiency of magnetic planar speakers implies that they generate little heat, even when playing a lot of music. This is crucial as a large amount can damage the voice coil and decrease the life span of the device.
This does not mean that all planar single-ended speakers are distortion free. Due to their close magnet spacing, the magnetic forces can interact with each the other and draw one another to a large extent, causing changes to the diaphragm's pressure over time. This problem is made worse due to the proximity of the adjacent rows of magnets.
Better Heat Dissipation
In the past few decades, a variety of specialization HiFi audio headphones companies have created incredible masterpieces with planar magnetic technology. Planar magnetic drivers have some amazing advantages over the conventional coiled dynamics used in most headphones and speakers.
The main benefit is that the "voice coil" is spread out over an area that is much larger than a conventional cone speaker that allows it to disperse heat efficiently without becoming too hot. This allows the voice coil to operate more efficiently and with less distortion, and also allows for an extremely lightweight diaphragm which can be driven to extremely high levels of excursion.
best planar headphones allows the planar magnetic speaker to have exceptionally quick transient response, which means that sharp peaks and very tiny details can be reproduced precisely even at very high SPLs. The sound that is produced is crystal clear without distortion and is indistinguishable from the original source material.
The impedance curve of the planar magnetic speaker is extremely flat, ranging from 4.2 ohms for the bass to 3.3 in the treble. This makes it an easy load to drive amplifiers, and is similar to the resistive loads that electronics manufacturers to demonstrate their products' quality.
A ribbon/planar diaphragm that is extremely light can move swiftly and without much strain. This results in a clear and clean sound with a wide bandwidth and superb linearity.
The ribbon/planar design is also very quiet, which decreases distortion even further. It is also very stable across a wide range of temperatures, allowing the speaker to provide consistent audio quality throughout long listening sessions and a wide listening area.
While there are numerous benefits to using a Ribbon/Planar Speaker, it is important to remember that this type of speaker is not suitable for all listeners or applications. For instance, a planar or ribbon speaker with a large radiating panel requires a very large room to produce full-range sound of sufficient SPL. For this reason, most these speakers are sold as tweeters or as the upper mid/high range part of a two-way system.
Higher Power Handling
Magnetic planar drivers deliver clarity and detail that is not matched by cone drivers. They can detect subtle details and reproduce complex sounds with precision. They also have a wide frequency response, which means they can produce a wider frequency range with greater precision.
Planar speakers create a highly directed sound field, which can be a disadvantage in the event that you're listening in a room with other people. But it's also what gives them their incredible dynamic range and stunning image. The sound seems to shoot directly out of the speaker, similar to the sound of a laser beam, which can be heard even when off-axis.
The flat diaphragm, when combined with the acoustic waves front, gives them a greater perception of space and depth than cone speakers. They typically have an extremely low noise floor, which makes them less distracting when in noisy environments. Many audiophiles prefer the natural sound quality of planar magnetic drivers over other technology.
However, there are limitations to the technology. Planar drivers are more difficult to create than conventional cone drivers, and they can be heavy, which can make difficult to install in certain conditions. They also require a higher power output to drive them, which could limit their maximum output.
Wisdom Audio is the leader in the development and application of PMD technology. The company's products continue to advance the boundaries of this innovative technology. Its new patented material is able to withstand temperatures far higher than PET that is used to make most planar drivers. Its unique design reduces the effects of diffraction, which can occur when sound waves travel through narrow gaps or curves.
As a result, its headphones and speakers are known to deliver an extremely clear and precise sound that isn't distorted. They also have a higher level of responsiveness than cone drivers, which could improve their bass response. They can also reproduce high frequencies with astonishing accuracy, and are capable of producing deep, powerful bass.
