Purifi PTT4.0X04-NAC-03
The 4” long-stroke 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 PTT4.0X04-NAC-03 features:
- Vibroacoustic optimized cone and dust cap in black anodized aluminum
- Negligible Force Factor Modulation (FFM) and Surround Radiation Distortion (SRD)
- Low Magnetic Hysteresis Distortion (MHD)
- "Real" long-stroke performance with distortion remaining low over full excursion
- Uncompromised midrange performance
- Designed and manufactured in Denmark
