Product Description

 Alpine SWS-12D4 12″ Subwoofer with Dual 4-ohm Voice Coils

The Alpine SWS-12D4 Type-S 12″ Subwoofer with dual 4-ohm voice coils’ bass pedigree runs deep in their latest line of Type-S subwoofers. Using technology found in their higher end subs, this sub will rock your system and add depth to your favorite tracks. You’ll love the detail it brings to a bass guitar and the impact you’ll feel when a kick drum hits. Throw a couple of these in your ride and prepare to be amazed by unrelenting bass.

Alpine SWS-12D4

Advanced materials

The Alpine SWS-12D4 Type-S 12″ Subwoofer with dual 4-ohm voice coils can handle up to 500 watts of RMS power, so you can drive it hard and it’ll keep up. The tough 12″ Kevlar treated cone stays rigid under pressure, while its rubber HAMRS surround allows for maximum excursion. Its dual 4-ohm voice coils allow for 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.
Note: If you are wiring this DVC sub for lower impedance, make sure that your amp is compatible.
To drive this single subwoofer, we recommend a mono amplifier rated between 375 and 750 watts RMS at 2 ohms.
The new fourth-generation Alpine SWS-12D4 Type-S 12″ Subwoofer with dual 4-ohm voice coils have undergone a revolutionary redesign, leaning heavily on patented technologies developed for the Type-R series. The result is a subwoofer that is so good we had to redesign the Type-R. These new subwoofers redefine the expectations in their class. Altogether, they offer significantly improved output, deeper bass extension, more control and even greater power handling.

More Excursion = More Output

The new FEA-Optimized Motor Structure together with our revolutionary HAMR Suspension Design gives the new Type-S Subwoofers the highest X-max and SPL output in the category. With a real-world, measured 15mm of one-way X-max, the new Type-S Subwoofers deliver best-in-class output, ultra-low distortion, and unparalleled sound quality. Borrowing the HAMR suspension from the Type-R, these new Alpine SWS-12D4 Type-S 12″ Subwoofer with dual 4-ohm voice coils have over 30mm of one-way stroke, for a total of nearly 3” of peak-to-peak excursion.

Underhung Design = More Control

The new dual-sided CRC motor structure mimics that of the Type-R Thin subwoofers, providing these subs with an ultra-linear, highly controlled sound. This patented design (US Patent # 6,639,993) creates a perfectly symmetrical and linear magnetic field for the coil to travel in, minimizing distortion while enhancing sound quality. The high-grade double-stacked magnets ensure adequate clearance for high excursion while providing the energy needed to power these beasts.

Keep it Cool = Keep it Playing

Alpine’s Patented Airflow Management System (US Patent #7,684,585) helps minimize power compression and ensures reliable long playing time by actively wicking output-robbing heat away from the Voice Coil. The massive 65mm (2.6”) diameter voice coil provides nearly double the surface area when compared to the previous 38mm (1.5”) voice coil. Similar to having a larger intercooler in a race car, the larger surface area allows for the voice coil to cool faster, ensuring that your bass tracks cleanly and reliably, without compression.

Massive Voice Coils = Maximum Durability

The new 6-layer (Dual 4Ù) and 5-Layer (Dual 2Ù) coils are wound on a spiral-cut aluminum former. The massive coil, along with the black anodized coating, provides these woofers the thermal mass and cooling capacity to achieve a full 500W of RMS power handling. Peak power…try 1500W.

High Strength Steel Frame

With such an advanced airflow system we have incorporated a high strength steel frame to keep the bass going while keeping your sub cooler.

8 AWG Push Terminals

Keeping power consistent to your woofers is just as important as keeping them cool. The 8 AWG Push Terminals are used on the Alpine SWS-12D4 Type-S 12″ Subwoofer with dual 4-ohm voice coils to keep power current flowing, allowing your subwoofer to get the power needed from the amplifier to run cool and consistent.

More Bass In Less Space

What is unique and amazing about the new Alpine SWS-12D4 Type-S 12″ Subwoofer with dual 4-ohm voice coils is not only the entirely new engineering behind the build, it’s the requirements for them to optimally perform. The new Alpine SWS-12D4 Type-S 12″ Subwoofer with dual 4-ohm voice coils specification requires 0.5-0.85 for the 10”, 0.65 – 1.0 for the 12”, and 1.25-2.0 for the 15” cubic feet air space for superior performance.

High-Grade Strontium Ferrite Magnets

Creates a symmetrical magnetic field with evenly distributed flux density to greatly reduce distortion, while further improving power handling and output.

Clean, Concealed Mount Gasket System

These Alpine SWS-12D4 Type-S 12″ Subwoofer with dual 4-ohm voice coils have a shallower mounting depth allowing for more application flexibility and the concealed mount gaskets give Type-S subs a clean finished appearance for any vehicle.
