Description
The 6.5” 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 PTT6.5X drivers especially in compact speaker construction where a traditional reflex port would limit the performance.
The PTT6.5PR-NA2-03 features:
- Vibroacoustic optimized cone and dust cap in black anodized aluminum
- PURIFI Neutral Surround eliminates Surround Radiation Distortion (SRD)
- 15mm one-way peak excursion with constant Sd
- Mass Plug with M6 thread for adding extra mass
- Designed and manufactured in Denmark
