Subwoofers for Serious ListenersPolk Audio rocked the car stereo world in the spring of 2005 with the introduction of the SR6500 Signature Reference component/coaxial system hailed by Car Audio & Electronics magazine as "...the best performance, the best cosmetics the best engineered" component system. The same attention to detail and performance we brought to the SR6500 system we now offer in the all-new Signature Reference SR124 and SR104 Subwoofers. Both models are designed to provide competition-grade bass performance when installed in small sealed enclosures (.88 cubic ft net volume for the SR104 and 1.2 cubic ft net volume for the SR124).
SR Signature Features:
Massive die-cast aluminum basket to house the 16 pound motor structure.
A 2.5 inch glass/epoxy voice coil former wound with four layers of heavy gauge high temperature Aluminum wire provides the highest power handling and reliability.
Voice coil is bathed in cooling air via an extensive network of vents in the pole piece and basket.
Specially designed curved vanes smooth the airflow to minimize air turbulence that could cause noise and “chuffing.”
Dual progressive roll spiders precisely control the cone’s long excursion for the ultimate in “tight,” detailed and musical bass.
Polk’s Klippel Distortion Analyzer, which uses laser technology to measure and optimize driver behavior under high output, helps maximize linearity, minimize distortion, flatten and extend frequency response.
ABS Cone employs catenary geometry for greater distortion damping stiffness.
NBR (Nitrile Butyl Rubber) Surround damps distortion inducing resonance as it stands up to harsh automotive environments.
Hex-key terminals (use a 2.5mm Allen key) for clean, professional hookups can accommodate up to 8 gauge speaker wire.
