Award-winning Polk Audio technology places the SR Signature Reference Series at the apex of high-performance car audio. The drivers use aerated polypropylene cones for maximum stiffness and minimum cone resonance, ensuring a tight, clean, articulate response. Nitrile butyl rubber surrounds, laser-optimized, vented 2-layer Kapton voice coils and formers, and case aluminum baskets with extra heat dissipating features, all contribute to the SR Series' professional sound quality and outstanding reliability.
The mid/bass driver cone is Aerated Polypropylene in which air is injected into Polypropylene to produce a honeycomb structure that serves to stiffen and damp the cone without adding mass. This is the same cone technology employed in Polk's critically acclaimed LSi Series audiophile-grade home speaker line.
1-1/2" Polyimide Voice Coil Former provide high thermal stability (rated to 220°C) high power handling, low mass and superior bass output.Neodymium Magnet Structure
Finite Element Analysis (FEA) design makes the powerful neodymium magnet more linear for lower distortion and higher definition. Small Neo magnet makes the SR5250 easier to fit into more locations and vehicles.
