Data Sheet:

Description

This 6.5" is a member of the ultra low distortion woofer family from PURIFI. Compared to the renowned PTT6.5X family, the W-version has higher sensitivity and is well suited for applications that doesn't require extended excursion.
The driver incorporates the easily recognizable PURIFI NeutralSurround suspension and ultra-linear motor system PURIFI PureDrive technology working in concert to elevate performance to a whole new level despite of it’s compact size.

The PTT6.5W08-NFA-01 features:

  • Vibroacoustic optimized cone and dust cap in proprietary paper fiber mix
  • Negligible Force Factor Modulation (FFM) and Surround Radiation Distortion (SRD)
  • Ultra Low Magnetic Hysteresis Distortion (MHD)
  • Best mix of volume displacement and midrange efficiency
  • Uncompromised midrange performance
  • Designed and manufactured in Denmark
