Audeze LCD-3 Planar Magnetic Headphones
The Best in the World
Our flagship headphone has literally been called the best in the world. At the pinnacle of our LCD Collection, the LCD-3 delivers the highest resolution music experience Audeze offers.
Strongest Driving Force
The LCD-3 has the longest voice coil and the strongest diaphragm driving force yielding the fastest transient response of all the LCD Collection.
Patent-pending Fazor elements guide and manage the flow of sound in the headphone for improved clarity and focus, greater frequency extension top and bottom, and remarkable 3D holographic imaging. The LCD-3 must be driven by an external headphone amplifier or integrated amp.
What makes Planar Magnetic headphones so cool?
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.
Planar magnetic transducers offer numerous benefits:
- 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.
- Frequency and Distortion: The magnetic force that drives the lightweight diaphragm delivers rapid acceleration thus achieving a wide frequency response, low distortion and excellent sound quality.
- Durability: 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 Friendly: The circuits found in planar magnetic diaphragms present an almost purely resistive load to amplifiers, making it 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.
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.
