Planar Magnetic Loudspeakers and Ribbon Tweeters

planar closed back headphones magnetic drivers such as ribbon tweeters, and other dynamic speakers have many advantages. Their diaphragms are comparatively large and require only a tiny amount of movement (excursion) to reproduce the same sound quality like a conventional driver, resulting in very low distortion.

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

High-Resolution Sound

Planar and ribbon magnetic speakers are renowned for their ability to create precise, clear sound. They are known for delivering high-resolution, revealing subtle variations in music that other drivers are unable to reproduce or reveal.

The planar and ribbon drivers are not just accurate, they also have superior soundstages, which allows them to recreate a vast soundstage with outstanding clarity. Audiophiles, home theater enthusiasts and audiophiles will find them to be a great choice.

Planar and ribbon drivers can be distinguished by their dipole pattern. This pattern emits equal amounts of energy front and back in an inverted phase, creating a natural soundstage. Their broad dispersion and dipole radiation pattern make them ideal for large spaces, where they can create an authentic and spacious soundstage.

Planar magnetic drivers have a fast response time which allows them to reproduce transients more accurately and more quickly than cone drivers. This results in a highly clear and precise sound, even at very high frequencies.

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

In addition, the distance between the magnets in a planar driver is much larger than that of a traditional cone speaker. This allows for a higher frequency response and lower distortion at lower amplitudes, while still providing excellent bass performance.

Despite their many benefits, planar magnetic drivers do have some limitations to take into consideration. They can be costly and require more power when compared to other kinds of speakers. Also, they can be large and difficult to place in some spaces. They are also sensitive to the acoustics in the room and require extensive treatment of the room to get the best performance. There are ways to minimize the effects. For example, you can add an attenuation resistance (provided with speakers) and place it in the attenuation mode. Or, you can perform some type of room treatments.

Wide Dispersion

Planar magnetic speakers also produce sound by controlling electrical currents that travel through wires that are suspended between magnets. They vibrate a flat surface directly, rather than using an electrostatic charge. This gives them greater surface area and greater precision. This principle allows them to be integrated into smaller and less expensive headsets and speakers as opposed to electrostatic models.

In addition to offering wide dispersion, planar drivers deliver superior imaging and clarity of soundstage, particularly in the higher frequencies where they excel. This is an excellent benefit for audiophiles who love watching movies or music on large screens or in an open space.

Additionally the planar drivers can also produce deep bass since they can be augmented with boxed woofers that are connected to or separate from the ribbon-like diaphragm. This is in contrast to traditional cone speaker woofers that are usually located in the bottom of the cabinet, which is a place that cannot reproduce bass frequencies due to the physical constraints of the enclosure that houses the woofer.

Another advantage of the planar driver is that it has extremely low distortion which is directly linked to the size and the excursion of the ribbon-like diaphragm. A planar speaker can produce a huge volume of sound without distortion. This is why the sound reproduction is so clear and precise.

In comparison the dynamic drivers that are used in standard headphones and speakers typically have significant distortion when driven to the limit of extreme excursion. This is why dynamic drivers often create a booming or hollow sound.

Finally, planar magnetic drivers are also extremely efficient. They require less power to drive, Planar magnetic speakers resulting in a lower power consumption and a less environmental impact. Furthermore, their diaphragms typically composed of lighter materials than traditional speakers, which reduces the amount of energy required to propel them to produce an appropriate sound pressure.

Many audiophiles are familiar with planar/ribbon loudspeakers - particularly the ones made by Magnepan, Infinity, and Apogee Acoustics - a new generation of brands are entering the market. For instance, new planar loudspeakers from manufacturers such as Diptyque and Clarisys Audio are incorporating the most recent advancements in ribbon technology.

Low Distortion

Since Planar Magnetic Speakers (Https://Www.Diggerslist.Com/65Fcc3992434B/About) don't have a conventional cone or dome shaped diaphragm they produce extremely low distortion. This is the direct consequence of their unique design, which eliminates the voice coil inductance associated with conventional dynamic speakers (see U.S. Patent 6,353,560). This means that the diaphragm is never being out of phase with its surroundings magnetic field, and therefore a constant output level. Most often, distortion occurs when waveforms with large amplitudes are reproduced. With a single-ended planar magnetic driver distortion is virtually nonexistent in all frequencies above the bass.

Planar magnetic loudspeakers are extremely efficient and have low distortion. This enables the drive to operate with much less power than is normally required by other types of speakers. This results in lower cost of ownership and lower energy consumption.

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

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

Planar magnetic drivers have many other advantages they offer, but the main advantage is that they can be designed as dipoles (radiating in opposite phases and equally in front and behind the speaker, similar to an ESL), or Monopoles (radiating in the forward direction and more like traditional dynamic speakers). This permits a wide range of designs, particularly when paired with using a ribbon-tweeter.

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

High Power Handling

Planar magnetic drivers are capable of handling a lot of power without the tension or strain that can be induced by traditional moving coil dynamic speakers. This is because the "voice coil" is spread across an expansive area instead of being squeezed into a narrow gap between the basket and cone like traditional dynamic drivers. This gives the voice-coil more surface area to absorb any heat.

Another reason that planar drivers can handle so much power is that they have the smallest mass when as compared to conventional drivers. Dynamic drivers feature diaphragms that are heavy and thick. They are a tenth of a pound heavier and thicker than the ultra-light diaphragms used in planar magnetic drive. Due to their massive mass, conventional diaphragms require a much larger amount of force to move back and forth (a measure called excursion) to produce an equal amount of sound pressure.

They aren't able to be driven nearly as hard as a planar magnet driver, because the voice coil will begin to produce significant distortion. Therefore, it is essential to purchase loudspeakers that are designed for the amplifier you're planning to use.

The high excitation of a planar magnetic driver also enables it to generate a much wider soundstage than conventional drivers. This is because the diaphragm vibrates in a uniform and flat way to create a wavefront, rather than the spherical wavefront that is typical with conventional drivers. This wider soundstage increases the precision and detail of the speakers and allows them to reproduce subtle nuances and more complex sound effects.

The drawback to the superior power handling of planar magnetic drivers is that they are often more expensive to manufacture and require higher-powered amplifiers in order to be driven at full capacity. They can also be heavy and bulky, which can make them difficult to install in some locations. They also tend to have a limited bass response, which means you may need to add a subwoofer to your system in order to get a satisfying result at lower frequencies.
