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.

The PTT4.0PR-NA2-02 features:

Vibroacoustic optimized cone and dust cap in black anodized aluminum

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
