Radius HP-NX100 Earphones
New developed RAF structure driver
By installing a chamber (air chamber) that accurately controls the back pressure behind the dynamic driver unit, we have developed and installed the “RAF structure driver” which realizes high braking performance of the diaphragm. By reducing vibration suppression of the diaphragm and occurrence of unnecessary vibration, it exhibits superior transient (transient) characteristics with improved response to the voice signal and less extra reverberation compared with the conventional driver.
The acoustic approach that arranges precisely designed chambers realizes a powerful but wide sound field and high spatial expression power. Flat frequency characteristics are shown without damaging the low frequency range with the original sound reproduction tendency.
Unique shape deep mount earpiece is different from the conventional type, earpieces fit in the back of the ear, realize a stable fit and rich bass reproduction.
The diaphragm adopts PEEK material which has high rigidity and better balance of propagation speed and internal loss than general PET material and which has high stability in the whole region. The voice coil adopts “CCAW” which is copper coated with aluminum wire. Because it is lighter than ordinary copper wire, it can be expected to improve the response of diaphragm and reduce unnecessary vibration. It enables excellent elongation of the high frequency range and bass playback with good crispness.
