Alpine S2-W8D4 2X4 ohm 8" subwoofer

S-Series subwoofers now also in Europe!
Up until now, Alpine's S-series subwoofers have only been available on the American market.
S-Series subwoofers have an unbeatable price-performance ratio, and the selection has the right element for everyone's needs!

Patented performance
S-Series subwoofers use numerous solutions patented by Alpine that you will not find from any other brand!

Patented magnetic solution, thanks to which the magnetic field can be symmetrical and the amount of distortion minimized. (US Pat#6639993)
Patented voice coil cooling, where cool air is supplied to the voice coil from behind the magnet and warm air is brought out of the voice coil through the ventilation ducts of the frame. (US Pat #7684585)
Patented H.A.M.R. upper suspension, where the trajectory of the cone can be kept under better control than traditional suspension. (US Pat #8208677)
Patented progressive lower suspension with integrated silver wires, which prevents possible mechanical interference sounds. (US Pat #6810988)

H.A.M.R.
High Amplitude Multi-Roll (H.A.M.R.) is Alpine's patented upper suspension. Compared to traditional suspension, H.A.M.R. with the suspension, the trajectory of the cone stays linear much better, especially when at higher volume the standard suspension starts to live a life of its own.

Carbon fiber/polypropylene cone
The cone material of the S-Series subbar is a combination of carbon fiber and polypropylene. Thanks to the light but sturdy cone, the reproduction of the eight-inch element reaches up to 35 hertz, producing a distortion-free and pleasant bass reproduction in its entire reproduction range, regardless of the music style.

Double coils and proper cooling
The Alpine S2-W8D4 has two four-ohm voice coils. The subbar comes with "jumpers" that you can easily make the connection you want. The spring-loaded terminals are placed next to each other, which makes connecting even easier.
Up to 8mm² speaker cable goes to the terminals.

The perfect companion for S2 amplifiers
The best amplifier for the S-Series subwoofer is the Alpine S2-A60M mono amplifier from the same model series.

Freedom of choice
Make exactly the set you want for your car. S-Series subwoofers are available in 8″, 10″ and 12″ versions, and each of these is available in 2 x 2ohm and 2 x 4ohm models.

"Ace" family
In addition to subwoofers and amplifiers, Alpine's "ace" collection also includes very popular stand-alone sets and coaxial speakers.
