Description:
The 4” passive radiator incorporates the easily recognizable PURIFI NeutralSurround suspension in order to eliminate Surround Radiation Distortion. With its low-distortion properties, long linear stroke and option for adding mass, the driver is eminently suited as a companion to the PTT4.0X drivers especially in compact speaker construction where a traditional reflex port would limit the performance.
Features:
- Vibroacoustic optimized cone and dust cap in proprietary paper fiber mix
- PURIFI Neutral Surround eliminates Surround Radiation Distortion (SRD)
- 14mm one-way peak excursion with constant Sd
- Mass Plug with M6 thread for adding extra mass
- Designed and manufactured in Denmark
