Both 12" 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 2 ohm, 4 Layer, Long Coil (2 ohm x or 2 ohm)
- TS-W307D4: Dual 4 ohm, 4 Layer, Long Coil (4 ohm x or 2 ohm)
The Premier TS-W307D2/4 subwoofers are designed to produce enormously powerful music. Just take a look at its super-heavy-duty construction, all designed to handle up to 1,200 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.
The 10" subwoofers have a maximum power output of 1000 watts.
- TS-W257D2: Dual 2 ohm, 4 Layer, Long Coil (2 ohm x or 2 ohm)
- TS-W257D4: Dual 4 ohm, 4 Layer, Long Coil (4 ohm x or 2 ohm)
Double-Stack Magnet
To produce the tremendous magnetic energy we envisioned for this sub, we employed double-stacked magnets, weighing a hefty 74 oz. 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.
Dual Voice Coil
These subs provide 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
