Pioneer’s Champion Series Subs

Superior Sound and Savings
Pioneer Champion Series subwoofers give you more bass for your budget. Delivering up to 1500 watts of exceptionally powerful thumping bass, this subwoofer enables you to build a great system at an affordable price.

Powerful Performance
Champion Series subwoofers boast Pioneer’s legendary design and reliability. Constructed with the highest-quality materials, including a rugged IMPP cone that handles loud volume and high temperatures, the Champion Series is built to last.

Installation Flexibility
To allow for greater flexibility and easy installation, all Champion Series speaker terminals have been placed on one side of the subwoofer rather than both sides like conventional subwoofers.

TS-W308D4 Features

Interlaced Basalt/Carbon Fiber Reinforced IMPP Cone
To ensure that you get more natural bass, we’ve incorporated out 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.

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-W308D2/4 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-G308. This stylish spoke grille is a must add-on when building a system and gives the look of pure professionalism.
