About the Alpine S-W12D2
Great bass in less space
Great bass in less space
To create great bass, you need the best in materials and engineering. Alpine's S-Series subwoofers apply technology from their higher end subs to bring you the depth and punch that'll make your tunes come alive. And to make things even better, these subs are about an inch shallower than their predecessors, making them great candidates for locations where regular high-power subs won't fit.
The S-W12D2 12" sub can handle up to 600 watts RMS, so you can drive it hard without any worries. The tough Kevlar® treated cone stays rigid under pressure, while its rubber High Amplitude Multi-Roll (HAMR) surround enables maximum excursion for impressive performance. Its dual 2-ohm voice coils allow for extra wiring flexibility, which helps if you plan on adding another subwoofer down the line. Also, it rocks in both sealed and ported boxes, so you can choose an enclosure that suits your tastes.
To drive this single subwoofer, we recommend a mono amplifier rated between 450 and 900 watts RMS at 1 ohm or 4 ohms. For more information, please refer to our article on How to Match Subwoofers and Amplifiers.

Alpine S-W12D2 reviews
Nothing beats an alpine subwoofer series S, but maybe a Series R

Sounds really good, 2 of these with my kicker amp pushes 1200rms total between them and it will hit so hard that I had to upgrade my charging system to keep up with it and everything in my car vibrates bad when it hits. If you want a cheaper setup that hits hard then get two of these with a kicker cxa1200.1 amp. You won't regret it.

Kevlar Reinforced Pulp Cone: This Alpine S-Series subwoofer uses a parabolic cone structure, with a Kevlar reinforced pulp cone and a Poly-Mica-Talc dust cap. Kevlar adds strength and tear resistance to the woofer cone while maintaining the benefits of a pulp cone material. The oversized, inverted dust cap increases rigidity and virtually eliminates cone distortion at extreme volume levels.
HAMRS: The woofer features a High Amplitude Multi Roll Surround (HAMRS) that allows a large linear excursion and greater SPL. The HAMRS design allows extreme excursions without sacrificing valuable cone area.
Progressive Spider: The progressive spider has reinforced layer tinsel leads to ensure reliable and consistent control of the tinsel leads and eliminate any mechanical noise or interference often seen in high excursion cone designs.
Compound Radius Curve Pole Geometry: Alpine's Patented Compound Radius Curve extended pole geometry ensures a symmetrical magnetic field, while optimizing flux density to reduce distortion and further improve power handling and output.
Dual Voice Coils: For system flexibility, the woofer has two 2Ω voice coils. When the voice coils are wired in parallel, the woofer presents a 1Ω load. When the voice coils are wired in series, the woofer presents a 4Ω load.
Spring Terminals: The spring post terminals are all located on one side of the woofer. The terminals will accept pin connectors, single banana plugs, or bare wire up to 8 gauge.
Jumpers: Included with the woofer are two voice coil terminal jumpers. These jumpers allow you to easily wire the voice coils in parallel (for a 1Ω load) or series (for a 4Ω load).
Sealed Box: Alpine recommends a sealed enclosure with an internal volume between 0.61 and 1.06 cubic feet, with an ideal volume of 0.85 cubic feet. Sealed enclosures provide the most control over a woofer, will handle a lot of power, and provide accurate sonic reproduction, making them suitable to all types of music.
Ported Box Volume: The recommended ported box volume ranges from 1.06 cubic feet to 1.56 cubic feet, with the ideal size being 1.51 cubic feet, using a slot port measuring 12-1/2" (W) x 1" (H) x 16" (L).
