Planar Magnetic Loudspeakers and Ribbon Tweeters
Planar magnetic drivers, ribbon tweeters and other dynamic speakers have many advantages. Their large diaphragms only require just a tiny amount of movement (excursion) and allow them to produce the same sound quality as traditional speakers.
They also have dipolar radiation patterns, which means that they radiate equally in front and behind the speaker.
High-Resolution Sound
They are known for their precise, detailed sound effects. They are known for their high-resolution sound that reveals subtle nuances in music that other drivers are unable to reproduce or even reveal.
The planar and ribbon drivers aren't just accurate, but also offer superior soundstages, allowing them to reproduce a huge soundstage with incredible clarity. Audiophiles, home theater enthusiasts and audiophiles will find them be an excellent choice.
Planar and ribbon drivers are distinguished by their dipole pattern. This pattern radiates equal amounts of energy front and back in an inverted phase, resulting in a natural soundstage. Their wide dispersion and dipole radiation pattern makes them ideal for large spaces, where they are able to create an open and natural soundstage.
Planar magnetic drivers have a fast response time, which allows them to reproduce transients more accurately and more quickly than cone drivers. This produces a clear and clear sound even at very high frequencies.
Another advantage of planar magnetic drivers is their low distortion. This is due to the fact that they do not use an actual voice coil, but rather an electrostatic field. This allows the diaphragms move without causing vibrations which could cause unwanted distortion.
A planar driver also has a larger gap between the magnets than a cone speaker. This results in a better frequency response and lower distortion at lower amplitudes but still delivering high-quality bass.
Despite their many advantages planar magnetic drivers have some limitations to take into consideration. For instance, they could be expensive and require more power than other types of speakers. Additionally, they can be heavy and difficult to install in some spaces. Additionally, they are sensitive to the sound of the room and require extensive room treatment to ensure optimal performance. There are several ways to reduce these issues, such as by adding an attenuation resistor (provided with your speakers) in the attenuation position, or by using some form of room treatment.
Wide Dispersion
Like electrostatic speakers magnetic speakers produce sound by regulating the electrical current that flows through wires suspended between magnets. However they directly vibrate a flat diaphragm, rather than an electrostatic charge, which gives them a larger surface area and greater precision. This operational principle also makes it possible to build them into smaller, more affordable headphones and speakers compared to electrostatic models.
Planar drivers aren't just capable of dispersing sound effectively they also offer higher quality image and clarity in higher frequencies. This is a huge advantage for audiophiles who enjoy listening to their favourite music or films in the living room of a large size or other open space.
Additionally, planar drivers can produce extremely deep bass because they can be augmented with boxed woofers that are connected to or independent of the ribbon-like diaphragm. This is in contrast to traditional cone-shaped speakers that feature woofers that are located at the bottom, which cannot reproduce bass frequencies because of the physical limitations of woofer enclosures.
A planar driver has a low distortion rate, which is directly proportional to the size and movement of the diaphragm. This means that a planar speaker can produce an extremely high volume of sound with little distortion, which is why it can produce such crisp and precise reproduction.
In comparison the dynamic drivers that are used in traditional headphones and speakers typically show significant levels of distortion when they are driven to extreme excursion limits. Dynamic drivers can give an enveloping sound or a boomy sound.
Planar magnetic drivers are extremely efficient. They are less energy-intensive to drive, resulting in a lower energy consumption and impact on the environment. Their diaphragms that are generally lighter than traditional speakers, also decrease the energy needed to propel them in order to create a certain sound pressure.
Many audiophiles are familiar with planar/ribbon loudspeakers, particularly those made by Magnepan, Infinity, and Apogee Acoustics - a new generation of brands is making their debut. New planar loudspeakers by manufacturers such as Clarisys Audio and Diptyque, for instance, feature the latest advancements in ribbon technology.
Low Distortion
Since planar magnetic speakers do not 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 speaker drivers (see U.S. Patent 6,353,560). This assures that the diaphragm not out of phase with the magnetic field around it, resulting in a constant output. The distortion is typically only evident when large waveforms are being reproduced. With a single-ended planar magnetic driver, distortion is nearly nonexistent at all frequencies above the bass.
In addition to their ultra-low distortion and low distortion, planar magnetic loudspeakers provide extremely high efficiency. This enables the drive to be used with a much lower power consumption than is normally required for other speaker technologies. This results in lower operating costs and reduced energy consumption.
The distortion of planar magnetic drivers is significantly lower than traditional dynamic speakers, and even more than electrostatic speakers. This is because a planar magnet driver's flat diaphragm is equipped with a conductor trace that lets it to react to magnetic fields generated on either side.
These two magnets must be carefully positioned to ensure that the voice element is properly placed within the magnetic field at all times. straight from the source allows magnetic drivers that are planar to function at a very consistent level across all frequencies higher than bass.
While there are numerous other advantages of planar magnetic drivers, the most significant is the fact that they can to be constructed to be dipole (radiating equally and in opposing phases both in front and back of the speaker, similar to an ESL) or Monopole (radiating forward, much like an old-fashioned dynamic). This opens the door to many different possible designs, particularly when paired with a ribbon tweeter.
Many planar magnetic loudspeakers can be found today from manufacturers like Hifiman, Dan Clark, Audeze, and Fostex. Each manufacturer has its own distinctive sound that is the result of their own patented driver configurations and other technological innovations. These speakers are characterized by their amazing clarity, dynamic, and controlled directionality.
High Power Handling
Planar magnetic drivers can handle large amounts of power without the audible strain or stress that can be induced by traditional dynamic speakers that move. This is due to the fact that the "voice coil" is spread out across an expansive area instead of being squeezed into a tiny gap between the cone and basket like traditional dynamic drivers. This gives the voice-coil more surface area to absorb any heat.
Planar drivers can handle so much power because they are light compared to conventional drivers. Dynamic drivers have thick, heavy diaphragms which are several orders of magnitude larger and heavier than ultra-light diaphragms found in planar magnetic drives. Due to their massive mass, these diaphragms need a larger amount of force to move between them (a measure known as excursion) in order 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 can begin to create significant distortion. This is why it's important to only purchase loudspeakers that are rated for the type of amplifier you're planning to drive them with.
The high frequency of an acoustic driver also allows it to create a wider soundstage than conventional drivers. This is because the entire diaphragm vibrates to create an even, flat wavefront instead of the more centered spherical wavefront found in conventional drivers. This larger soundstage also increases the accuracy and detail of the speakers which allows them to better reproduce subtle nuances and more complex sounds.
The disadvantage of the superior power handling capabilities of planar magnetic drivers is that they are often more expensive to manufacture and require higher-powered amplifiers to be driven at full capacity. They can also be heavy and large and can be difficult to install in certain situations. You may also need to install a separate subwoofer if you want to get satisfactory results at lower frequencies.
