The D is a result of Pioneer’s automotive loudspeaker engineering experience and expertise, combining advanced design techniques with highly developed manufacturing capabilities. Following Pioneer’s OPEN & SMOOTH sound concept, the D series of automotive loud speakers provides broad and balanced frequency response with a wide sound stage, ambience and amazing fidelity for the listener.
Aramid Fiber Interlaced Injection Molded Polypropylene (IMPP)
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.
The D full range speakers are designed with a universal woofer basket to expand installation flexibility for maximum bass and sound quality.
