Description

Why would you want an Alpine SWS-12D4 in your car? If you are looking for subwoofers that can add depth to your music soundtracks and rock your system, Alpine SWS-12D4 can meet those expectations.

This 12″ Dual-Voice-Coil 4-Ohm sub is a fourth generation subwoofer, Alpine’s latest line of revolutionary Type-S subs. It uses Alpine’s patented technologies typically found in the brand’s higher end subwoofers. It is equipped with a surround design, the High Amplitude Multi-Roll, known as H.A.M.R., providing extreme excursion and creating precise and better output. The sound quality is highly controlled and has little distortion due to the symmetrical magnetic field produced by having a dual-sided motor.

Large Surface Area

The larger surface area of the airflow management system can let you play tracks for long hours without a glitch. The broad surface area can significantly reduce power compression to dissipate the heat away from it in less time. Despite the extreme excursion, interferences and mechanical noises do not pose a problem because of Alpine’s unique patented sub reinforcement called “Layer Spider Integration.”

If you want a sub that hits hard, trust SWS-12D4 to deliver and sustain the pace. It is a tough subwoofer that’s built to handle up to 500 watts of RMS. It is designed to have dual 4-ohm voice coils allowing wiring flexibility to accommodate additional subs down the line, whether in ported or sealed boxes. It has a reinforced Kevlar pulp cone that stays firm under pressure. Another amazing feature is the fact that it requires less air space for optimal performance.

Accurate Transients

All these make the Alpine SWS-12D4 deliver the output clearly. You’ll love the details of the sounds – the impact of the bass drum, the hits of the kick drum and the details of the bass guitar. What is even more amazing is how it clearly delivers the low pitch bass in tracks like dubstep and rap. Altogether, the features offer considerable output capability, impressive control and more accurate transients, deeper bass extension, and superior power handling.
