Pioneer exclusive P.F.S.S. spider

The Progressive Flex Suspension System (P.F.S.S.) effectively supports the voice coil by damping cone vibrations and improving the linearity of sound reproduction. Its soft part ensures smooth movement and clear sound even under high power, while its firmer part controls excessive vibrations and prevents unwanted movements that cause distortion. The goal is simple: to provide all the details of your music while maintaining control during the large excursions generated by the bass.


Loud & Aggressive Sound

Engineered for high-impact performance, it features a Mica Reinforced Cone that enhances movement speed and efficiency, delivering louder, clearer sound with remarkable precision. Whether you’re cruising down the highway or stuck in traffic, this speaker fills your car with deep, aggressive sound.
