Alpine S2-W12D2


Performance and Value

With an impressive power handling of 600W RMS and a peak power handling of 1800W, the Next-Gen 12” S-Series Subwoofers deliver outstanding performance value. Boasting a wide frequency response range of 23Hz to 215Hz and a sensitivity of 86dB (1W/1m), these subs ensure powerful and accurate bass reproduction across a diverse range of music genres.

Enhanced Punch

Featuring the lightweight yet sturdy combination of carbon fiber and polypropylene, the Next-Gen S-Series Subwoofer cone delivers deep, low-distortion bass that enhances the depth and richness of your music.

HAMR Surround

Alpine-exclusive High Amplitude Multi-Roll (HAMR) surround technology is integrated into the speaker design which allows for maximum cone movement, delivering powerful and accurate bass notes.

Flexible Application

A dual voice coil (DVC) with easy configuration jumpers make installing the s-series subwoofers a breeze. A new twist-lock grille mounting system makes it easy to install and remove an optional grille without mounting screws for added protection to the cone.

Perfect Power Match

Maximize the potential of your s-series subwoofers with Alpine's perfectly power-matched s-series amplifiers. Power a single S2-W12D2 subwoofer effortlessly with the 600 watts S2-A60M mono amplifier, or for a even bigger impact, pair two or more S2-W12D2 subwoofers with the powerful 1200 watts S2-A120M amplifier to ensure optimal sound quality and performance.

Good

The following review is for a previous version (SWS-12D2).

I bought two of the 12 inch type s subs and am happy with them. They arnt the loudest but are worth the money. Great for someone getting into the sub game

Alpine Subs

The following review is for a previous version (SWS-12D2).

Worked great in my application, always have had good experience with Alpine products. The dual voice coil configuration makes it easy to order what you need to run your subs at 2 ohms.

Great sub and great price!

The following review is for a previous version (SWS-12D2).

Alpine has never let me down. This subwoofer hits extremely hard. I have one powered by an alpine mrv-m500 wired at 4 ohms in a ported box. The amp is only at the normal output power setting and that's all I need. This sub is a great buy for anyone who wants the perfect amount of bass to not drown out the music completely. Don't get me wrong though, this sub is capable of doing that if you want it to.

Yeaaaaa!

The following review is for a previous version (SWS-12D2).

If u know me I like bass! I have 2 of these in the ground shaker 2 12 sqp
Box and it slams. I was surprised cause that's really nota big box. Imagine
A custom box! Other than that I have it hooked up to a brutis 1200 @ 2 ohms. Good subs.

descent!

The following review is for a previous version (SWS-12D2).

This speaker was second choice in regards of finding one that had high temp voice coils. I hooked it up to class d autotek1500d and dropped ohms to 1. I broke it in over three weeks and then as soon as she started banging good, it blew. It had great sound but maybe sealed box and hot summer day banging didn't go well? Either way can't really be mad it was good just not good enough for my application. Vented boxes keep speakers cooler just don't have that tight low I like so if you like sealed set up then get something that can handle the heat!

Best subs around for the price

The following review is for a previous version (SWS-12D2).

Started with a 10" alpine type E that is now in my girlfriends toyota celica. Bought 2 of these for my car and they sound amazing no matter what style of music im listening to. I couldnt say enough good things about these subs. Extremely satisfied with all alpime products, especially the type S subs.

It Alright

The following review is for a previous version (SWS-12D2).

I have owned two of these both have broken on me. Thee first was my fault and the second was a factory issue but would not honor warrenty. They sounded awesome when they worked. I had only one hooked up at a time in a ported box with a alpine mrv500 amp.

bass shaking, hard hitting, deep low traveling bass by far!!!!!

The following review is for a previous version (SWS-12D2).

I had just replaced 4 10" orion cobalt subwoofers in a 5 cubic foot box ported at 45hertz. with a sws12d2 subwoofer in a 1.5 cubic foot L vented wedge box tuned at 35.1 hertz. this thing hits as hard as my old 4 orion 10" and hits as low as the 4 10". for the price of this sws you get more then your money's worth!!! this sub slams hard in my hatch back!!! I've been thinking bout getting a sws15d2. don't get me wrong the 12 is loud n hits low. but im a bass head!!!! to the fullest!!!

excellent budget sub

The following review is for a previous version (SWS-12D2).

Great service from the guys at sonic electronix as always. Sub is one of the best bangs for the buck. It sounds great paired with my hifonics amp. I can't imagine how it would sound if I built a tuned box
