Pioneer Premier 12" Champion Series Pro Subwoofer - TSW3002D4

Pioneer Premier 12" Champion Series Pro Subwoofer, Model TSW3002D4

The Premier TS-W3002D2/4 subwoofers are designed to produce enormously powerful music. Just take a look at its super-heavy-duty construction, all designed to handle up to 3,500 watts max. Double-stacked magnets for higher power, and a step-up radial surround for superior control and long excursions. We used a constructed cast-aluminum basket for this sub. Add in our patented IMPP cone and you've got a monster sub that can handle whatever you want to throw at it — including Pioneer's new breed of SPL amplifiers like the PRS-D1200SPL.

Features:

• Air Suspension System
  For its revolutionary 3.25 inch deep Shallow Subwoofer, Pioneer created an Air Suspension system effective within a 70% smaller-than-previous enclosure that locks air for a spring-like effect between main and drive cones moving in unison. The result is consistently clear,powerful,wide ranging bass response. The subwoofer's dual cone structure maintains better sound linearity and reliability after hours of hard use than conventional subwoofers with "spider" structures to keep the voice coil aligned. This incredible technology is applied to this new generation of high output, high performance subwoofers
• Double-Stack Magnet with Double-Stack Top Plate
  To produce the tremendous magnetic energy we envisioned for this sub, we employed double-stacked magnets, weighing a hefty 110oz, and a double-stacked top plate above them. This design ensures positive, powerful control of the voice coil during those long excursions — and it's one reason you can ring up those high SPL numbers
• Wide-Roll 3-Layer Fiber Radial Surround
  A sub's surround plays a key role in a speaker's 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. In addition, the wider-than-normal design provides a long, linear excursion for excellent control and heavy-duty durability
• 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
• Cast Aluminum Basket
  Designed from scratch by Pioneer, this one-piece aluminum basket assembly holds the motor assembly, cone, and magnet structure securely in place. The benefits of this design: reduced internal stress, superior damping, and increased magnetic efficiency
• Dual Voice Coil
  TS-W3002D2/D4 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. The Bridging Adapter is included for an easy Single Voice Coil hookup. It becomes a Single 4 Ohm or Single 8 Ohm with Bridging Adapter for ultimate flexibility for use with modern mono amplifiers
