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.
