Pioneer TS-W307D2/D4 Champion Series Subwoofer

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 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-gauge wire.

IMPP with Aramid Fiber Cone
Pioneer is the world's 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 we've combined this with Aramid fiber, a material used in the manufacture of bulletproof products. This combination produces a cone that's incredibly strong, very light, and very rigid. In other words, it's perfect for a high-performance subwoofer.

3-Layer Radial Surround
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.

Dual Mass Magnet with Magnet Cover
It's 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 that's 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 won't 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: that's what DVC is all about.

Add Newly Designed Spoke Grilles
We also recommend covering up your subwoofer with the UD-G307. This stylish spoke grille is a must add-on when building a system and gives the look of pure professionalism.
