PEEK Performance Drivers
The 40 mm PEEK Performance Drivers offer a smooth and balanced 2 Hz – 23.5 kHz frequency response, 112.5 dB max. SPL, and low distortion. They are combined with a light-weight neodymium magnet system for crystal-clear sound and are tested during production and assembly to achieve a stereo-matched result.
What is PEEK and why does it matter?
In the world of diaphragms, light weight and stiffness are key. Without these qualities, a driver can be too heavy to be efficiently driven by the electrical signal coming via the voice coil and magnet. Alternatively, it can be too flexible which can result in muddy performance and distortion at certain frequencies.
Polyether Ether Ketone (also known as PEEK) is considered to be an excellent driver material for dynamic headphones due to its thermal characteristics which result in a lower “glassing point” (the point at which a material solidifies). This means it is more rigid and can retain its advantageous weight and stiffness properties in a wider range of applications, especially when pushed at higher temperatures where cheaper materials such as PET would start to deform.
Neodymium Magnet System
As with diaphragm construction, the choice of material for the magnets also has a tangible bearing on driver performance. Both in terms of weight and ability to efficiently transmit electrical signals into physical movements, Neodymium is the top choice for high quality headphone drivers.
