• Air Suspension System
  For its revolutionary 3.25 Inch deep 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
• 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
• IMPP Cone with Carbon Fiber/Glass Fiber Reinforcement
  Pioneer invented the process of injection-molding polypropylene to form a speaker cone. We call them IMPP cones, and they're exceptionally strong and lightweight. Now, we've reinforced IMPP with carbon and glass fiber, providing speaker cones with extraordinary strength and rigidity — and light weight. This is ideal for powerful, accurate music. And it gives the cones the durability needed for withstanding heat, humidity, and dust
• 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-W3001D2/4 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. 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
• Available Tuned Subwoofer Enclosure
  The available UD-W12 SPL Optimized Ported Enclosure is the perfect complement for the TS-W3001D2/4 subwoofer. It features a ported design that provides optimum performance and delivers tight, thunderous bass output
