"LCD Fans Will be Tickled Pink"
Audeze's new LCD-4 reference headphone is the result of dedicated research and development and advancements in materials science. It features Audeze's amazingly thin nano-grade diaphragms and unique Double Fluxor magnet arrays for the most powerful magnetic flux density in existence, delivering an incredible 1.5 Tesla! The LCD-4 also features a new, ultra-comfortable suspension-type carbon fiber and leather headband.
Most crucially, it offers breathtaking, high resolution sound, imaging, and transparency with exciting dynamics. The LCD-4 sounds incredibly open in the midrange and treble, and coupled with Audeze's powerful bass, this headphone removes the boundaries between artist and listener. It outperforms other headphones in its class, including electrostatics or dynamic driver headphones. It provides Audeze's most advanced planar magnetic technology to date.
"The LCD-4 is a clear improvement over previous LCD models both technically and musically with better clarity, and bass through mid-range control and evenness. Audeze LCD line fans will be tickled pink with the LCD-4," notes Tyll Hertsens, innerfidelity.com, March 25, 2016.
Fluxor™ Magnetic Technology
Patent-pending Fluxor magnetic technology delivers super powerful magnetic flux density. This remarkable achievement results in reduced weight with greater efficiency. This headphone is sensitive enough to be driven directly by portable music players.
Uniforce™ Diaphragm Technology
The LCD-4's Uniforce diaphragm employs an industry first. Variable trace widths in the voice-coil to effectively capture variations in the magnetic field within the magnetic gaps by equalizing the forces of the individual traces, creating a uniform driving force across the entire diaphragm surface. This results in dramatically reduced distortion, higher resolution, and improved imaging.
Audeze's Fazor technology, introduced in the LCD Collection, is also integrated into the LCD-4. Fazors are special acoustical elements positioned on either side of the magnetic structure. They enhance transparency by affecting the sound waves generated by large planar diaphragms. A few of the benefits include extended frequency response, improved high-frequency extension, and lowered distortion, with better imaging.
Audeze Planar Magnetic Transducer Technology
Planar magnetic speaker technology is a dramatic departure from traditional dynamic speakers. The unique design and functionality of planar magnetic transducers (or drivers) overcome many limitations inherent in cone drivers.
Planar magnetic transducers typically consist of two main components: a diaphragm with circuit and magnet arrays. The 'planar' in planar magnetics refers to the magnetic field that's distributed in the same plane (parallel) to the diaphragm. Planar magnetic diaphragms are thin and lightweight compared to much heavier moving-coil or dome diaphragms found in 'dynamic' drivers. This thin diaphragm is suspended in the magnetic fields created by the magnetic arrays.
Unlike a dynamic driver with a cone or dome attached to a voice coil, a planar magnetic diaphragm has a printed circuit spread across the surface of a thin-film substrate. When the circuit is energized with an audio signal, it interacts with the magnetic field and produces an electromagnetic force that moves the diaphragm back and forth creating sound.
Audeze employs a number of proprietary techniques that improve upon basic planar magnetic design, including the integration of unique, ultra-thin diaphragms and stronger and more optimized magnetic fields and circuit patterns. Audeze's goal is to bring the best in planar magnetic design and continuing to improve the personal audio experience.
Planar Transducer Advantages
Planar magnetic transducers offer numerous benefits compared to dynamic drivers, beginning with enhanced responsiveness. Since the force created by the magnetic field is distributed across most of the diaphragm surface, the planar magnetic diaphragm moves faster and with far greater accuracy to the input signal.
The magnetic force that drives the lightweight diaphragm delivers rapid acceleration thus achieving a wide frequency response, low distortion and excellent sound quality.
Planar magnetic transducers also offer added durability compared to conventional dynamic drivers. Because the circuit pattern is spread flat across the diaphragm surface, it can dissipate the heat generated by the current passing through it more efficiently. Additionally, planar magnetic transducers have few moving parts and can maintain performance without any sonic degradation. Dynamic drivers continuously degrade in performance over their life due to a multitude of moving parts and use of glue joints.
Amplifier friendliness is another attribute. The circuits found in planar magnetic diaphragms present an almost purely resistive load to amplifiers, making the transducers easy to drive. The impedance over the entire frequency range is completely flat vs. dynamic speaker, which could have variances in impedance values over the frequency range.
