Pioneer TS-D10D4 subwoofer

If your vehicle’s audio system is not giving you the sound you want, the TS-D10D4 10″ subwoofer might be what you are looking for. It was built to handle up to 500 W RMS with the ability to deliver impressive low frequencies. This subwoofer features an injection-molded polypropylene IMPP™ cone infused with Aramid fibers for exceptional precision and strength. The butyl rubber surround supports the subwoofer during cone excursion resulting in low distortion of the bass notes even when the music is turned up loud.
IMPP D Series
Polypropylene (PP) is a tough thermoplastic resin, ideal material for a speaker cone. The low mass and high damping of a PP cone generate 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 cone is ultra-thin and low mass with high rigidity and superior strength, built to produce natural, detailed sound with deep and powerful bass.

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.

Voice Coil & Magnet
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. The D subwoofer uses an oversized 4-layer voice coil and high energy double stacked magnets to increase the overall power handling and SPL output with no sacrifice in sound quality.
