Our Product Research Team
At Crutchfield, you'll get detailed, accurate information that's hard to find elsewhere.
That's because we have our own in-house Product Research team — they open the box,
verify contents, check the owner's manual, and record dimensions, features and specs.
We stay on top of new products and technologies to help people make informed choices.
Dual-Layer IMX Aramid/Basalt Fiber Composite Cone: The Pioneer
D-Series speaker features Dual-layer IMX (Injection-molded Matrix) aramid/basalt
fiber composite cone woofers. 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. The woofers also have
butyl rubber surrounds for a smoother response, heat resistant voice coil, and
5.3-ounce Strontium magnets.
Rear Chamber Tweeter Enclosure: The Pioneer D-Series
speakers feature an exclusive rear chamber tweeter enclosure. This design
extends mid-range frequency for improved vocal imaging and staging. The
TS-D1702R's 1-1/8" soft dome tweeters also utilizes wave guides to control sound
dispersion to make sound stage wider in the car. In addition, the tweeter uses a
magnetic fluid neodymium magnet for higher efficiency.
High-Quality Passive Crossover Network: The built-in HPF (-12 dB/oct.)
and LPF (-6 dB/oct.) 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.
Grilles: The speakers come with black steel mesh grilles
with silver heat-proof resin frames.
Mounting Ring: The supplied mounting ring has mounting holes
for various 6-3/4" applications, allowing the speaker to fit more vehicles. In
most cases, the ring should be used to mount the speaker.
