GET CLOSER TO NATURE—
NEW OPEN & SMOOTH SOUND
With their extra-wide directivity, low tweeter crossover frequency and distortion, plus light, rigid IMPP cones,
Pioneer’s PRS speakers realize a level of in-car audio quality that deserves its own name: “Open & Smooth”
sound—a wide-open sound staging, rich, natural midrange and tweeter output with outstanding
smoothness and linearity.
Superior Directivity: Pioneer PRS Speakers
Pioneer PRS speakers always maintain more open, smooth,
expansive, multidimensional sound, without the dramatic
dips and inconsistencies that lesser speakers can produce
when angled in certain directions.

Pioneer advances the proud heritage of its IASCA (International Auto Sound Challenge
Association) award-winning Premier Reference Series. These speakers’ superior
response, linearity and sound directivity improve low- and mid-frequency
reproduction, while making highs and lows sound smoother and more open. Micro Fiber Surround: Maximum Musical Response
The strong, high-density micro fiber material surrounding the woofer of a PRS speaker
is very light and low in resistance and internal loss characteristics. This enhances
linearity of the short winding length of the voice coil, thereby optimizing efficiency.
Moreover, micro fiber doesn’t stretch so it does a better job than other materials to
control vibration and enables higher power input.
The result is faster response and more accurate
bass reproduction that allows all
music to be heard to greatest
advantage.
2nd-Generation Multilayer Cone: First-Class Sound Reproduction
For the PRS speakers, Pioneer also developed a multilayer woofer cone in an even
better formulation, sandwiching composite foamed IMPP using interlaced aramid fiber
between a woven carbon-blended aramid fiber layer and a glass fiber layer. This rigid
cone structure provides impeccable midrange frequency reproduction and overall
sound quality. The cone material is also supremely light and uniform in its physical
properties because it is made without adhesives
using an advanced injection molding process.
