Pioneer TS-W309D4 12" Champion Series DVC Subwoofer

Pioneer's Champion Series Subwoofers feature an all-new design and look. The TS-W309D4 subwoofer has a maximum power output of 1400 watts. For extraordinary performance, the subwoofer's cones are made of Pioneer's IMPP with Aramid Fiber, and we've 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 AWG wire.

Why does Pioneer 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). To ensure that you get more natural bass, Pioneer incorporated new Basalt fiber technology into our shallow subwoofers. The volcanic-rock fibers create a cone that is lightweight, rigid, well damped, stable in temperature extremes, and more environmentally friendly. In short, this bass really rocks. A sub's 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. That's why Pioneer created a surround consisting of two layers of urethane, with a layer of interwoven fiber between them. It's strong, stable, and it reduces distortion. TS-W309D4 provides two voice coils so you can use a low-impedance amp to produce much bigger, much more powerful bass. More options, more power: that's what DVC is all about.
