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.

Features

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.
