Introducing our new Champion Series Subwoofers which feature an all-new design and look. Both subwoofers have a maximum power output of 1200 watts. You now have a choice to select from either a Dual-Voice Coil 2-ohm or 4-ohm subwoofer: TS-W307D2: Dual-Voice Coil Design 2 ohm x 2 TS-W307D4: Dual-Voice Coil Design 4 ohm x 2 For extraordinary performance, the cones are made of Pioneers IMPP with aramid fiber, and weve used a dual mass magnet assembly for higher magnetic force — and more power. The wire terminals are spring-loaded and can take up to 8-gauge wire. IMPP with aramid fiber Cone Pioneer is the worlds largest car speaker manufacturer, and our work in advanced materials and manufacturing processes has led to major breakthroughs in mobile audio. One of these was IMPP (Injection-Molded Polypropylene), which allowed cones to be lighter AND more rigid. Now weve combined this with Aramid fiber, a material used in the manufacture of bulletproof products. This combination produces a cone thats incredibly strong, very light, and very rigid. In other words, its perfect for a high-performance subwoofer. 3-Layer Radial Surround A subs surround plays a key role in its overall performance. In order for bass response to be clear and tight, the surround has to respond evenly around its entire circumference without flexing or puckering, even at high volume levels. Thats why Pioneer created a surround consisting of two layers of urethane, with a layer of interwoven fiber between them. Its strong, stable, and it reduces distortion. Dual Mass Magnet with Magnet Cover Its simple, really. Follow us here: to accurately drive and control its voice coil, a speaker needs a magnet and a pole yoke, to create magnetic force. The bigger or denser the magnet, the greater the magnetic force. The greater the magnetic force, the greater the power and control thats exerted over the voice coil. To make this happen in a big way, we use a Dual Mass Magnet assembly (weighing in at 83oz.) to significantly increase the magnetic force. SO, you get bigger and more accurate music. And yes, we even included a magnet cover. Spring-Compression Binding Posts Why do we use Spring-Compression Binding Posts, instead of standard speaker wire terminals? So your speaker wire NEVER shakes loose due to vibration (either from the road or from your music). When you insert the wire, the connector keeps a constant pressure on it. And it wont let go. These binding posts will accept wire as large as 8-gauge. Dual Voice Coil TS-W307D2/4 provides two voice coils, each either at dual 2 or dual 4 ohms. So you can use a low-impedance amp to produce much bigger, much more powerful bass. More options, more power: thats what DVC is all about. used but in brillent condition these still are 120 dollors each to purchse new so it wud b just over 200 pounds.. these will comes in proper inphase mdf air tight box worth 45 pounds alone i want 85 pounds or very nearest offer.
