To create the new D-Series speakers for the Pioneer TS-D1720C components, 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.
Rear Chamber Tweeter Enclosure
D-Series speakers feature an exclusive rear chamber tweeter enclosure that we first used in our famed PRS speakers. It extends mid-range frequency for improved vocal imaging and staging.
High-Quality Crossover
The built-in -12dB/Octave HPF and LPF crossover improves the transition from mid to high frequency, for a smoother mid-range to tweeter response. Audiophile-grade capacitors and inductors are used, and all components are encased in a clear acrylic cover for protection.

Reviews worldwide have rated these components very highly and no wonder with the sound they produce. My only advise would be to amplify them tho just to get the max out of them as they have a 88 dB sensitivity rating which pretty much dictates that an amp would be necessary.
Other than that they are a very well built speaker and the weave on the mid-range cones are so beautiful I would want people to see them and they sound just as good as they look!
