Pre-Owned Paradigm Reference Studio Sub 15 Subwoofer

Pre-Owned Paradigm Reference Studio Sub 15 Subwoofer This unit is sold as-is. In-store collection preferred. Condition Notes: 1 × Subwoofer 1 × Grille (broken pins) 1 × Power cable No manual No original packaging Chip on the back of the unit above the amplifier module High-Excursion Bass Drivers These proprietary drivers were designed, engineered and manufactured by Paradigm in North America: 12˝ (308 mm) in the SUB 12 and 15˝ (380 mm) in the SUB 15. With unwanted resonances, standing waves and micro-distortions non-existent, these subwoofers display incredible definition, awe-inspiring dynamics, lightning-fast speed and gut-wrenching power. Mineral-Filled Co-Polymer Polypropylene Cones with RCR™ Resonance Control Ribs: Engineered for very high power, the high-stiffness design is intrinsically low in distortion, allowing the bass cone to respond instantly to the starts and stops of even the leading edge of changing bass notes. Large High-Pressure Die-Cast Aluminum Chassis Dual-Voice-Coil Design — 3-Inch (76 mm) Aluminum Voice Coils: Wound on high-temperature Kapton® formers in an oversize configuration, the multi-layer voice coils provide exceptional linearity and motor strength. Advanced Multi-Layer Polyurethane-Composite Elliptical Surrounds and Dual Oversize Spiders: Optimized using Finite Element Analysis (FEA), the surrounds' multi-layer composite matrix, with its high-tech surface treatment, encourages staggering peak-to-peak excursion — with exceptional linearity and cone control. Large Aluminum Shorting Rings: Situated around the voice coil, the rings improve linearity and heat dissipation, and help reduce voice coil inductance and distortion. Proprietary AVS™ Airflow Ventilation System Cooling: Large built-in ribs increase the heat dissipation surface, providing forced-air cooling during large musical transients and chassis convection cooling at all other times. Extruded-Aluminum Center Heatsinks: Provide internal forced-air cooling to drive heat away from the FEA-optimized pole piece, increasing power handling while reducing distortion. 35-lb (15.8 kg) Magnet Assemblies with Balanced Field Geometry: FEA-optimized to produce a powerful high-density symmetrical magnetic forcefield while minimizing inductive distortion. Transient and phase response, power handling and output linearity are all exceptional.
