PIONEER CAR TSD12D4 D Series 12-inch 2000 Watt Max Power, Dual 4 Ohm Voice Coil, Aramid Fiber IMPP Cone, Rubber Surround – Component Subwoofer, Black || GENERAL || * Size : 12 inch || * Continuous Power Handling (RMS) : 600W || * Maximum Peak Power Handling : 2,000 Watt Max Power (600W Nom)|| * Impedance : Dual 4Ω Voice Coil || * Woofer Composition : Aramid Fiber Interlaced Injection Molded Polypropylene (IMPP) || * Woofer Surround : Butyl Rubber Surround for Strength and Linearity During High Excursion || * Woofer Magnet Composition : Ferrite || * Magnet Weight : 74.1oz || * Mounting Depth : 157mm || || AUDIO || * Sensitivity (1W/1 m) : 78dB || * Frequency Range : 20 Hz – 4.7 kHz || BUTYL RUBBER SURROUND || Made of a specially blended, highly durable and moisture-resistant compound, butyl rubber keeps the cone moving in a linear direction, seals the cone to the basket and quickly dampens cone vibration once the signal has changed or stopped. This results in less distortion and superior frequency response. || ARAMID FIBER INTERLACED INJECTION MOLDED POLYPROPYLENE (IMPP) || Polypropylene (PP) is a tough thermoplastic resin that is an ideal material for a subwoofer cone – with low mass and high damping, PP cones offer good sensitivity and low distortion. However, polypropylene cones lack the rigidity and strength required for high output and extreme low bass. || To resolve this, Pioneer engineers used advanced Computer-Aided Manufacturing to develop a process to blend aramid fibers into the polypropylene resin during the injection molding process. The resulting Aramid Fiber Interlaced IMPP subwoofer cone is incredibly strong and low mass with high rigidity and superior strength to produce deep, powerful and undistorted bass. || LARGE DIAMETER VOICE COIL AND DOUBLE STACKED MAGNETS || A subwoofer motor structure consists of the voice coil and magnet assembly. Increasing the diameter and length of the voice coil provides greater control of the woofer cone and higher power handling. To take full advantage, however, the magnet must also be increased, both in magnetic power and physical size.
