Absolute fidelity to musical sources takes form from speakers that reproduce the ambience in which sounds originate. Stage size, musicians’ movement, aural reflection and other distinctive details all bring these sounds to life. Pioneer D-Series speakers are available in 2-way component packages or 2-way coaxial designs in multiple sizes that fit most vehicles. To create new D-Series speakers, Pioneer developed the industry’s first basalt fiber made from natural rock interwoven with aramid fiber. Used in the surface layer, this dual-layer IMX (injection molded matrix) aramid/basalt fiber composite material is highly rigid and better absorbent, enhancing stability and maintaining integrity throughout a wide temperature range.
