It's A Planar Magnetic Loudspeakers Success Story You'll Never Believe
Planar Magnetic Loudspeakers and Ribbon Tweeters

Planar magnetic drivers such as ribbon tweeters, and other dynamic speakers have a number advantages. Their large diaphragms only require just a tiny amount of movement (excursion) which allows them to produce the same sound quality as an ordinary speaker.

They also have dipolar radiation patterns, which means that they radiate equally in front and behind the speaker.

High-Resolution Sound

Ribbon and planar magnetic speakers are known for their ability to deliver precise, detailed sound. They are known for their high-resolution and reveal subtle nuances in music that other drivers can't reproduce or show.

In addition to their impressive accuracy in sound reproduction, planar and ribbon drivers have superior soundstages, allowing them to reproduce an expansive soundstage and exceptional clarity. linked internet page and home theater enthusiasts as well as audiophiles will find them to be a great choice.

Planar and ribbon drivers are distinguished by their dipole pattern. This pattern emits equal amounts of energy in front and back in an inverted phase, resulting in an organic soundstage. This, along with their wide dispersion, makes them suitable for large spaces, where they can fill the room with a a broad and natural soundstage, without causing unnatural reflections off the furniture and walls.

Planar magnetic drivers also have a fast response time, which enables to reproduce transients with greater precision and speed than conventional cone drivers. This results in a clear and precise sound, even at very high frequencies.

Another benefit of planar magnetic drivers is their low distortion. It is because they don't use a voice-coil, but an electrostatic field. This allows the diaphragms move without causing vibrations that can cause distortion.

Additionally, the distance between the magnets in a planar driver is bigger than the gap in a conventional cone speaker. This results in a better bass and a better frequency response even at low levels of amplitude.

Despite their many benefits, planar magnetic drivers have some limitations to be aware of. They can be expensive and require more power to other types of speakers. They can also be heavy and difficult to fit into some rooms. They are also sensitive to the acoustics of the room, and require extensive treatment of the room to achieve optimal performance. However, there are solutions to minimize these problems for example, by putting an attenuation resistor (provided with your speakers) in the attenuation position, or by performing some type of room treatment.

Wide Dispersion

Like electrostatic speakers magnetic speakers produce sound through the regulation of the electrical charge that travels through wires that are suspended between magnets. They vibrate a flat surface directly, not using an electrostatic charge. This results in a larger surface area and greater precision. This allows them to be built into smaller and more affordable headsets and speakers as opposed to electrostatic models.


Planar drivers aren't just capable of dispersing sound efficiently and efficiently, but also provide higher quality image and clarity at higher frequencies. This is an enormous benefit for audiophiles who like listening to their music or movies in the living room of a large size or other space that is open.

Planar drivers can also produce an extremely deep bass since they can be augmented by boxed subwoofers that are that are attached to or separate from the membrane that resembles a ribbon. This is in contrast to traditional cone speaker woofers, which are typically placed in the bottom of the cabinet, which is a place which is unable to reproduce bass frequencies because of the physical constraints of the woofer enclosure.

Another benefit of a planar driver is its exceptionally low distortion, which is directly related to the size and length of the ribbon-like diaphragm. This means that the planar speaker can deliver an extremely high volume of sound with minimal distortion, which is why it produces such clear and detailed reproduction.

Dynamic drivers found in conventional speakers and headphone typically exhibit significant distortion when they are driven to their maximum limit of excursion. In the end, dynamic drivers typically produce a hollow or boomy sound.

Planar magnetic drivers are extremely efficient. They are less energy-intensive to drive, which results in a reduced energy consumption and impact on the environment. Their diaphragms that are generally lighter than traditional speakers, also decrease the amount of energy required to propel them in order to create a certain sound pressure.

Many audiophiles have heard of speakers made of ribbon and planar such as those manufactured by Magnepan Infinity and Apogee Acoustics. However, an entirely new brand is on the market. New planar loudspeakers by manufacturers like Clarisys Audio and Diptyque, for instance, are incorporating the latest advances in ribbon technology.

Low Distortion

Planar magnetic speakers have very low distortion since they don't utilize the conventional dome-shaped diaphragm or cone. This is the direct result of their unique design which eliminates the voice coil inductance that is associated with conventional dynamic speakers (see U.S. Patent 6,353,560). This guarantees that the diaphragm is not out of phase with the magnetic field around it, which results in a constant output. Most often, distortion occurs when high-amplitude waveforms are reproduced. With a single-ended planar magnetic driver, distortion is virtually nonexistent at all frequencies that go beyond the bass.

In addition to their extremely low distortion and low distortion, planar magnetic loudspeakers provide extremely high efficiency. This allows the drive to use much less energy than other technologies for speakers. This results in lower cost of ownership and a lower energy consumption.

Planar magnetic drivers also have a significantly lower distortion than conventional dynamic speakers and even less distortion for electrostatic speakers. This is because the diaphragm, which is flat, of the planar magnetic driver has a conductor trace that allows it to react to magnetic fields created by magnets on either side of it.

The two magnets must be placed in a way that the voice element stays in the magnetic field at optimum levels throughout the time. This is what allows for the extremely linear performance of planar magnetic drivers in all frequencies above the bass.

There are numerous other advantages of planar magnetic drivers, the most significant is that they are able to be constructed to be either dipole (radiating equally and in opposing phases in front and back of the speaker like an ESL) or monopole (radiating forward, much like an old-fashioned dynamic). This opens the door for many different possible designs, especially when combined with ribbon tweeters.

A variety of planar magnetic loudspeakers are available today from brands such as Hifiman, Dan Clark, Audeze and Fostex. Each company has a signature sound that results of their unique driver designs as well as other engineering breakthroughs. These speakers are characterized by their incredible detail, dynamic, and controlled directionality.

High Power Handling

Planar magnetic speakers can handle a lot more power than traditional moving coil dynamic drivers without the tension and strain they can cause. This is due to the fact that the "voice coil" is spread out across an extensive area instead of being squeezed into a small gap between the cone and basket like in traditional dynamic drivers. This gives the voice coil an increased surface area to disperse any heat.

Another reason why planar drivers are able to handle so much power is due to having such a low mass compared to conventional drivers. Dynamic drivers employ diaphragms with heavy, thick diaphragms that are a tenth of a pound heavier and thicker than the diaphragms that are ultra-light and thin used in planar magnetic drivers. Due to their high mass, conventional diaphragms require more force to move backwards and forwards (a measurement referred to as excursion) to produce the required sound pressure.

In the end they aren't able to be used by the same force as a planar magnetic driver could because the voice coil could begin to generate substantial amounts of distortion. Therefore, it is essential to purchase loudspeakers rated for the amplifier you intend to use.

A planar magnetic driver's large excursion enables it to create an even larger soundstage than conventional drivers. This is because the diaphragm vibrates uniformly and flat to form waves, instead of the spherical wavefront that is typical of conventional drivers. This larger soundstage also increases the clarity and accuracy of the speakers, allowing them to better reproduce variations and more complex sounds.

The drawback to the superior power handling of planar magnetic drivers is that they are often more expensive to produce and require more powerful amplifiers to operate at maximum capacity. They can also be quite heavy and large, which can make them difficult to install in certain situations. They also tend to have a lower bass response, so you may need to add a subwoofer your system to achieve satisfying results at lower frequencies.
