With these Pioneer TS-D6902R 2-way car speakers, you can fill your vehicle with high-quality music with a tap of your audio receiver. Pioneer designs D-Series speakers with Open & Smooth technology. What this term means is that frequency waves will seem to spread out with a controlled sound dispersion. They cover the entire vehicle with the same depth of sound as the immediate space around the 80-watt nominal RMS speakers.The cone of each speaker consists of an extremely rigid fiber, which helps to stabilize the frequency waves that come through the speakers to facilitate a fantastic listening experience. The woofer's surface layer is constructed of a mixture of natural rock and aramid fiber. Pioneer refers to this basalt-fiber configuration as a dual-layer IMX that only enhances the tones and physical structure of each audio speaker. Pioneer TSD speakers incorporate a basket design, providing a rich, deep bass response. These speaker baskets are about 7-inches deep, which allows the frequencies to bounce around at a controlled rate within the cone as they eventually make their way into your ears. Allow for a cutout dimension of about 6 inches by 8.7 inches during installation of the aramid and basalt cone so that the TS-D6902R speaker sits comfortably in its secure location.Measuring in at 1.125 inches, the tweeter in this car audio boasts a slightly larger design than 1-inch tweeters. This extra surface area helps contribute to the clear, high-frequency tones from the neodymium magnet and magnetic fluid embedded in the speaker's construction. Your audio experience is also enhanced by the distinct, rear chamber that's enclosed at the tweeter. Mid-range frequencies will sing as the surrounding butyl rubber protects the entire car stereo system.Whether you are using these accessories for your car radio, navigation system, or CD player, the Pioneer TS-D6902R speakers offer a peak power of 360 watts. These coaxial accessories also have a crossover frequency of 2,800Hz so that you have ample versatility with sound as you move between musical genres. Enjoy a frequency response rate of 28Hz to 30kHz after you install these units in your car. This audio product can fit into car doors or rest in the back-window area if you can reach the wiring that's located in the rear with no problems. These connectors accept the bare wires of your receiver as they attach directly to the OFC copper voice coil wire. This assembly is also attached to a glass-imide voice coil bobbin that further enhances the product's rich tone.When you purchase one or two of these products, they come with a speaker grille that protects the woofer section below. The tweeter's housing rests just above the grille so that the high frequencies can flow out with no obstacles. When you have the grille and Pioneer product connected, each unit weighs slightly more than 5 pounds. These heavy-duty audio accessories should be supported by the car's frame and appropriate fasteners to achieve the smooth response you're looking for.
