Overview:

To advance the ideal of “Open & Smooth” sound, Pioneer referred to its hit PRS speakers to create new TS-D and TS-A speakers. The benefits are clear: extra-wide directivity, low distortion and extended frequency range in the tweeter, plus well-balanced midrange and tweeter output. The impact is huge: rich, dynamic detail; expansive soundstage; and natural-sounding smoothness and linearity from any source.
Dual-Layer IMX™ (Injection Molded Matrix) Aramid/Basalt Fiber Composite Cone:
To create new TS-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 Aramid/Basalt Fiber material is highly rigid and better absorbent, enhancing stability and maintaining integrity throughout a wide temperature range.Together, the Dual-Layer IMX™ Aramid/Basalt Fiber and IMPP Composite Cone provide for outstanding low and mid bass range fidelity, low distortion as well as extraordinarily detailed, accurate sound reproduction.
