        Product details PURIFI PTT5.25PR-NA2-01

        PURIFI PTT5.25PR-NA2-01 Passive Radiator

         

        The PURIFI PTT5.25PR-NA2-01 is a premium 5.25" passive radiator designed to extend low‑frequency output in sealed speaker systems without the need for a reflex port. Its aluminum cone and inverted dust cap provide a stable piston action that maintains consistent performance through its range of motion.

         

        The innovative PURIFI Neutral Surround suspension helps eliminate Surround Radiation Distortion, resulting in cleaner, more accurate sound reproduction. With a resonance frequency around 21 Hz and an effective piston area of 84.9 cm2, this passive radiator is suited for compact speaker designs seeking deeper bass extension.

         

        With a moving mass of 52 g and a compliance of 1.15 mm/N, the PTT5.25PR-NA2-01 delivers controlled excursion and responsiveness. The ±14.0 mm mechanical Xmax allows significant diaphragm movement for improved low‑end output. The M6 threaded mass plug lets designers adjust the mass for precise tuning to the specific enclosure and driver pairing.
