PTT5.25PR-NA2-01
5.25" Passive radiator with alu cone, inverted dust cap and total moving mass of 52g
Description
The 5.25” 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 PTT5.25X drivers especially in compact speaker construction where a traditional reflex port would limit the performance.
The PTT5.25PR-NF2-01 features:
- Vibroacoustic optimized cone and dust cap in black anodized aluminium
- 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
