TS-A120S4E


Voice Coil and 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.


IMPP Cone with Aramid Fibers

This A-series speaker cone has a blend of Aramid fibers interlaced with Polypropylene during the injection molding process to meet Pioneer's standards for sensitivity, low distortion, rigidity and strength.
