Planar Magnetic Loudspeakers and Ribbon Tweeters

Planar magnetic drivers and ribbon tweeters offer numerous advantages over traditional dynamic speakers. Their diaphragms are comparatively large and require only a tiny amount of movement (excursion) to reproduce the same sound level as a traditional driver, which results in extremely low distortion.

They also have a dipolar radiation pattern which means they radiate equally to the rear and front of the speaker.

High-Resolution Sound

Planar and ribbon magnetic speakers are renowned for their ability to deliver precise, detailed sound. They are renowned for their high-resolution sound that reveals subtle details in music that other drivers are unable to reproduce or reveal.

Planar and ribbon drivers aren't just precise, but also provide superior soundstages that allow them to reproduce a huge soundstage with incredible clarity. Audiophiles and home theater enthusiasts as well as audiophiles will find them to be a great option.

Planar and ribbon drivers are distinguished by their dipole pattern. This pattern emits equal amounts of energy in the front and back, with an inverted phase that creates an organic soundstage. Their large dispersion and dipole radiation pattern makes them ideal for large spaces, where they can create an authentic and spacious soundstage.

Planar magnetic drivers also have a fast response time, which helps them to reproduce transients with more precision and speed than conventional cone drivers. This results in a highly detailed and crisp sound, even at extremely high frequencies.

Another advantage of planar magnetic drivers is their low distortion. This is due to the fact that they do not use a voice coil, but rather an electrostatic field. This allows the diaphragm to move without creating vibrations that can cause unwanted distortion.

In addition, the gap between the magnets in a planar driver is bigger than the gap in a conventional cone speaker. This results in a better frequency response and lower distortion at lower amplitudes, but still delivering excellent bass performance.

Although many of the advantages of planar magnetic drivers appeal to you but they do have a few limitations that need to be thought about. For instance, they can be quite expensive and may require more power than other types of speakers. They can also be bulky, making it difficult to fit into specific spaces. They can also be sensitive to the acoustics in the room and require extensive treatment of the room in order to ensure optimal performance. However, there are solutions to minimize these problems, such as by adding an attenuation resistor (provided with your speakers) in the attenuation position, or applying some kind of room treatment.

Wide Dispersion

Like electrostatic speakers magnetic speakers produce sound through the regulation of the electrical charge that travels through wires suspended between magnetic. They vibrate a flat, conductive membrane directly, instead of using an electrostatic charge. This allows for an increased surface area and greater precision. This allows them to be built into smaller and more affordable headsets and speakers than electrostatic models.

In addition to offering broad dispersion, planar drivers deliver superior imaging and clarity of soundstage, especially in the higher frequencies, where they excel. This is a great benefit for audiophiles that enjoy listening to music or movies on large screens or in an open space.

Moreover they can produce extremely deep bass as they can be augmented by boxed woofers which are attached to or separate from the diaphragm-like ribbon. This is in contrast with traditional cone-shaped speakers that contain woofers at the bottom, which are unable to reproduce bass frequencies because of the physical constraints of woofer enclosures.

A planar driver has a low distortion rate which is directly proportional to the size and travel of the diaphragm. A planar speaker can create a large volume of sound with no distortion. This is the reason that the sound reproduction is so clear and detailed.

In comparison the dynamic drivers utilized in traditional headphones and speakers typically have significant distortion when they are driven to the limit of extreme excursion. In the end, dynamic drivers usually produce a boomy or hollow sound.

Planar magnetic drivers are extremely efficient. They consume less energy to drive, which results in a reduced energy consumption and a less negative impact on the environment. In addition, their diaphragms are typically made of lighter materials than standard speakers, which further decreases the amount of energy required for Planar Magnetic Loudspeakers them to generate a given sound pressure.

Many audiophiles have heard of planar/ribbon speakers like those produced by Magnepan Infinity and Apogee Acoustics. However, a new brand is now available. For example, new planar loudspeakers from manufacturers such as Diptyque and Clarisys Audio are incorporating the most advanced ribbon technology.

Low Distortion

Since planar magnetic speakers don't have a conventional cone or dome-shaped diaphragm, they produce extremely low distortion. This is the direct result of their unique design, which eliminates the voice coil inductance that is associated with conventional dynamic speaker drivers (see U.S. Patent 6,353,560). This results in the diaphragm never being out of phase with the surrounding magnetic field, which results in the output level remains constant. Distortion is generally only noticeable when large waveforms are reproduced. With a planar magnetic single-ended driver, distortion is almost nonexistent at all frequencies above the bass.

In addition to their low distortion and low distortion, planar magnetic loudspeakers provide very high efficiency. This enables the drive to operate with much less power than is normally required for other speakers. This translates into lower costs of ownership and less energy consumption.

The distortion of planar magnetic drivers is significantly lower than traditional dynamic speakers, and even more so for electrostatic speakers. This is due to the diaphragm, which is flat, of a planar magnetic driver has conductor trace that allows it to react to the magnetic fields generated by magnets located on either side of it.

These two magnets must be carefully placed to ensure that the voice element is properly placed within the magnetic field at all times. This is what allows for the extremely linear performance of planar magnetic drivers in all frequencies above the bass.

headset planar magnetic drivers come with a myriad of other advantages, but the most important is that they can be designed as either dipoles (radiating in opposite phases and equally in front and behind the speaker, similar to an ESL), or Monopoles (radiating in the direction of travel, more like traditional dynamic speakers). This allows for a variety of designs, especially when combined the ribbon-tweeter.

Many planar magnetic loudspeakers are available today from manufacturers such as Hifiman, Dan Clark, Audeze and Fostex. Each brand has its own distinctive sound that comes of their unique design of drivers as well as other engineering breakthroughs. These speakers are distinguished by their amazing clarity and their dynamic, as well as controlled directionality.

High Power Handling

Planar magnetic drivers are capable of handling lots of power without causing the tension or strain that can be induced by traditional moving coil dynamic speakers. The "voice coil" is not squeezed into the tiny gap between the cones and baskets as in traditional dynamic drivers. Instead it is spread over more of a large area. This provides the voice coil with a larger surface area to dissipate heat efficiently.

Planar drivers can handle so much power because they are so light compared to conventional drivers. Dynamic drivers employ diaphragms made of heavy, thick material that are several orders of magnitude larger and thicker than ultra-light and thin diaphragms used in planar magnetic drives. Due to their high mass, conventional diaphragms require more force to move backwards and forwards (a measurement known as excursion) to produce the required sound pressure.

Therefore they aren't able to be used as effectively as a planar magnetic driver could because the voice coil could begin to produce significant amounts of distortion. It's therefore important to buy loudspeakers that are rated for the amplifier you intend to use.

A planar magnetic driver's high excursion allows it to create more soundstages than conventional drivers. This is because the entire diaphragm vibrates to create an even, flat wavefront, rather than the more focused spherical wavefront common in conventional drivers. The wider soundstage also improves the precision and clarity of the speakers which allows them to reproduce more subtle variations and complex sounds.

The downside to the superior power handling of planar headphones magnetic drivers is that they are often more expensive to manufacture and require higher-powered amplifiers to operate at maximum capacity. They can also be heavy and bulky, which can make them difficult to install in certain locations. They also tend to have a limited bass response, which means you may have to add a subwoofer your system to get the best results at lower frequencies.
