  • Neodymium magnet optimized with FEA simulations of the magnetic flux for utmost control and fast response to the transients.
  • Extremely pure copper short circuit ring, for excellent very high frequency extension.
  • Die-cast aluminum face plate with profile optimized with FEA simulations to improve frequency response and dispersion.
  • Tetolon Fiber dome optimized with FEA simulations for lower distortion and improved dispersion in high frequency range.
  • Frame structure and rear load chamber both derived from a CNC machined solid aluminum block, to ensure mechanically inert response to resonances.
  • Rear chamber sized for only 900 Hz Fs: low Fs ensures wide extension in low frequency range and low distortion also in the crossing section, allowing a decreased cut-off frequency.
  • High-density damping material underneath the dome, low-density absorbing material in the rear chamber, providing fluid acoustic emission and high damping in the low frequency response.
