- Soft Tetolon fiber dome tweeter featuring a 20 mm mobile voice coil cooled with ferrofluid, for natural and extended high frequencies.
- Radial Venting System technology including 8 venting holes for an excellent cooling of the voice coil and a natural mid range, featuring a low tweeter Fs, thanks to the air exchange with the support that acts as a large rear chamber
- 25mm diameter pure copper coil to guarantee high excursions.
- Pressed paper cone with FEM-optimized geometry combining rigidity and lightness for color-free sound.
