Alpine SWS-12D2 12" 1500W Dual 4-Ohm Type-R Series Car Subwoofer

Alpine SWS-12D2 12" 1500W Dual 4-Ohm Type-R Series Car Subwoofer

The new fourth-generation Type-S subwoofers 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.

Genetically Built Like Type-R
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.

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 Type-S woofers to keep power current flowing, allowing your subwoofer to get the power needed from the amplifier to run cool and consistent.

High-Grade Stontium Ferrite Magnets
Creates a symmetrical magnetic field with evenly distributed flux density to greatly reduce distortion, while further improving power handling and output.
