Magnetic Planar Speakers - Holographic 3D Imaging and Stunning Clarity
With a thin diaphragm suspended between 2 arrays of magnets that vibrate, they create sound waves. Planar magnetic speakers are renowned for their holographic 3D imaging and breathtaking clarity.
They are also ideal for a broad range of audio applications because of their low distortion, broad vertical and horizontal dispersion and cost-effective prices.
Superior Sound Quality
Planar magnetic speakers are renowned for delivering clear, precise sound with minimal distortion. They accomplish this by employing a flat diaphragm with a conductive pattern on it. This is a reaction to the magnetic field produced by magnets on one or both sides of a speaker. The diaphragm moves and causes sound waves to be transmitted through the dipole-radiation pattern. This allows the diaphragm to move more evenly and produce better sound quality than a typical cone or dome driver.
Another advantage of planar magnetic drivers is their wide, uniform dispersion that lets the sound be heard equally from any location in the room. In addition dipole or planar ribbon speakers provide an incredibly natural soundstage that has very little resonance. This creates an experience of listening that is difficult to duplicate with other types speakers.
Due to their large surface area, planar magnetic speakers are also more durable than conventional cone drivers. They can operate at higher volume levels without producing excessive vibration or distortion. They are also quieter than other types of speakers, making them an excellent choice for home theatre and HiFi applications.
Due to their intricate design, planar drivers may be more expensive than other types of loudspeakers, but they have superior audio quality that is well worth the investment. Planar speakers also have a lower impedance compared to other types of loudspeakers. This makes them more convenient for amplifiers drive.
Planar magnetic speakers are an excellent option for both home and professional use. However they aren't as popular in IEMs because they require more complex engineering to be able to fit into smaller sizes like headphones and earbuds. Recently, however, there is a surge in the number of IEMs that have planar magnetic technology. The Rinko by Seeaudio and the S12 and Z12 from LETSHOUER are just two examples of IEMs that have proven to provide a great listening experience.
Lower Distortion
For many audiophiles, the most desired characteristic of a speaker headphone is its low distortion. Voice coil inductance is the most common cause of distortion in speakers. When an alternating current is pumped through a typical moving coil driver's voice coil, the inductance of the voice coil produces magnetic fields that cause diaphragm movement. The movement, or excursion, is what causes the sound wave, however it also generates unwanted resonances and harmonics that diminish the quality of audio.
One of the main advantages of magnetic planar speakers is that they have much less distortion than traditional drivers. planar magnetic in ear is because the "voice coil" has an increased surface area rather than being squeezed into a small space within a massive piece of metal. A well-designed planar magnet speaker can handle much more power than a dynamic driver, but without audible strain.
Planar magnetic speakers can also reduce distortion by presenting the perfect resistive load to the amplifier in the system. The voice coil is a long, thin wire which behaves like a 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 these speakers is that they generate less heat even when playing high-pitched music. This is important because a large amount of heat can damage the voice coil, reducing its lifespan and increasing distortion.
This does not mean that all planar magnetic single-ended speakers are free of distortion. Because of their close magnet spacing, magnetic forces can interact and draw each other to a large degree, which can result in changes to the diaphragm's tension in the course of time. This issue is made more difficult due to the close proximity of adjacent rows of magnets.
Better Heat Dissipation
Many specialist HiFi audio headphone manufacturers have been creating amazing masterpieces in recent years that use planar magnetic technology. Planar magnetic drivers have some impressive advantages over the common Coiled Dynamics used in the majority of headphones and speakers.
The main benefit is that the "voice coil" is spread across a much larger surface area than a typical cone speaker, allowing it to dissipate heat efficiently and not get too hot. This allows the voice coil to operate more efficiently and with less distortion and also permits a diaphragm that is light and can be driven at very high levels of excursion.
This allows the planar magnetic speaker to have an extremely quick transient response, which means that sharp peaks as well as tiny details can be reproduced very accurately even at very high SPLs. This also means that the sound produced is very clean and free of distortion, and is indistinguishable from the original source material.
The planar magnetic speakers has a very flat impedance curve, from about 4.2 ohms in the bass, to 3.3 ohms in the treble. This makes it an easy load for amplifiers to drive and comparable to the resistive loads used by electronics manufacturers for tests designed to show how great their products are.
A ribbon/planar diaphragm that is extremely light and compact can move quickly and without strain. This creates a crystal clear and clean sound with a wide bandwidth and excellent linearity.
The ribbon/planar design is extremely quiet, which helps to reduce distortion even further. It is also extremely robust across a wide range of temperatures, which allows the speaker to maintain a an even sound quality over long periods of time and over an extensive listening area.
Although there are many advantages to using a Ribbon/Planar Speaker however, it is crucial that you remember that this type of speaker is not appropriate for all listeners or applications. For instance, a ribbon/planar speaker with a large radiating panel requires an extremely large space to provide full-range sound at an adequate SPL. Most of these speakers are available as tweeters, or as upper mid/high range components in two-way speaker systems.
Higher Power Handling
Magnetic planar drivers can deliver amazing clarity and detail without distortions that plague traditional cone drivers. They can reveal subtle variations and reproduce complex sound precisely. They have a wide range of frequency response which allows them to create a wider frequency range with greater accuracy.
Planar speakers produce a directional sound, which can be a problem when you are listening to them with others. It's also what gives them their incredible dynamic range and pristine imaging. The sound is like a laser beam, that shoots directly out of the speakers. It can be heard when you are off-axis.
The flat diaphragm and acoustic wavefront give them an enhanced sense of depth and spaciousness than conventional cone speakers. They typically have an extremely low noise floor, which makes them less distracting in noisy environments. Planar magnetic drivers are preferred by a lot of audiophiles due to their natural sound quality.
However, there are some limitations to the technology. Planar drivers can be more difficult to make and heavier than cone drivers. They are also difficult to mount in certain conditions. They also require a greater power output to drive them, which could restrict their maximum output.
Wisdom Audio is the leader in the development and application of PMD technology. Its products continue push forward the limits of this innovative technology. Its new patented materials can withstand temperatures far higher than PET, which is the material used in the majority of planar driver. Its unique design also minimizes the effects of diffraction, which can be caused by sound waves traveling through small gaps and curves.
This is why its speakers and headphones 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 helps enhance their bass response. They can also reproduce high frequencies with amazing accuracy, and are capable of delivering deep, powerful bass.
