Pioneer PIOTSD1002R 4-Inch 110W 2-Way Speakers

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 Aramid Basalt Fiber material is highly rigid and better absorbent, enhancing stability and maintaining integrity throughout a wide temperature range. 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.


  • Four-inch, two-way speakers with 110 watts maximum power handling (25 watts nominal)
  • Woofers feature dual-layer IMX aramid/basalt fiber composite cone with butyl rubber surround
  • 1-1/8-inch soft-dome tweeters with magnetic fluid and neodymium magnet
  • Built-in crossover with -6dB/octave low-pass and -12dB/octave high-pass filters
  • 40 Hz to 40 kHz frequency response with 86 dB sensitivity
