Excel Graphene W22NX001
The new W22NX001 (E0077-08) represents a successor to the famous W22EX001 (E0022-08) from SEAS, and it's been upgraded like other products with the new graphene cone technology, as well as new (and in this case longer) voice coil with titanium former and magnet system with copper rings and caps and a thicker ferrite magnet, designed and optimized for lower distortion and high powerhandling.
Here's the datasheet for the new driver: W22NX001
Low mechanical and electromagnetic damping ensures high quality reproduction of even the finest micro details in music. At the same time the high-performance titanium voice coil former and its connection to the cone has very high power-handling, suitable for modern amplifiers (e.g. Class-D). Therefore, the driver has exceptional high dynamic capability, which the light and stiff and well damped magnesium cone transfers into clean and undistorted sound, suitable for modern High-Res audio.
