Premium Sound & Refined Details

The Signature Reference series is the best automotive speakers Polk has ever produced. Your vehicle and music deserve top-notch, audiophile sound! We spared no expense bringing you the finest design and materials to this ultra-premium line of autosound speakers and subwoofers. Every component in the system- from the cast aluminum crossover enclosure, to the tweeters and woofers were designed and constructed with meticulous attention to detail. SR Series compaxial systems and subwoofers offer the finest looks and sound for your high end autosound application!

Ring Radiator Tweeters

The same exotic, sweet, airy sounding Ring radiator tweeters from our LSi and RTS line is now available for your car. Included are straight and 15° angle flush mount. These tweeters extract every ounce of detail from your music to reveal all the nuances you might have never even known existed.

Advanced Drivers

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.
