Description

The 6.5” midrange driver has been optimized for midrange use and achieves higher sensitivity as compared to the X- and W- versions of the PTT6.5 product family. 
It incorporates the easily recognizable PURIFI NeutralSurround suspension and ultra-linear motor system PURIFI PureDrive technology resulting in astounding performance with ultra clean distortion specifications.

The PTT6.5M08-NAA-08 features:

  • Vibroacoustic optimized cone and dust cap in black anodized aluminum
  • Negligible Force Factor Modulation (FFM) and Surround Radiation Distortion (SRD)
  • Ultra Low Magnetic Hysteresis Distortion (MHD)
  • Dedicated midrange driver with enhanced efficiency
  • Designed and manufactured in Denmark
