Black cone insted of the red that can be seen on the pic.

This series builds on the foundation of the PL series, but with new approaches to further enhance the performance. With a high density, low resonance, airflow-optimized chassis it allows maximum airflow under the spider. The result is much lower compression of air in the magnet system, which has also been optimized to reduce distortion. A Wood-fibre cone and phase integrated dust cap is a new technology that strives for the optimum sound quality. Vifa has always been known for searching for the best sound and will only adapt the best materials to achieve this. Low Resonance Multi-roll Surround (LRMS) is another design element used in this series to reduce resonance.

Driver Highlights: Wood-fibre cone and dustcap, Multi-roll surround, low distortion magnet system, airflow optimized chassis


Driver Highlights: Neo magnet, Under hung motor system, exceptionally long linear stroke
