You can tell that Alpine's 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.
The SWS-12D4 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. For more information, please refer to our article on How to Match Subwoofers and Amplifiers.
A component sub is simply a speaker that's designed to reproduce bass once it's installed in a compatible enclosure. Think about the impact of a movie soundtrack in a big theater or even in your own home HDTV setup. A component sub can add the same kind of power to the music in your car. And a car sub is not all about the boom that you hear on a street corner (although that's cool too) - you can pair a component sub with your choice of enclosure to get bass just the way you like it, from tight and punchy to fat and loose. And once you experience music in your car with a well-tuned subwoofer, you'll never go back.
So the backdrop. I have a Titan king cab that I wanted to add some low end to. I'm not trying to win competitions just a little low end added to the factory setup. I had a Kicker "hideaway" and thought it was the best thing since sliced bread. It did exactly what I wanted it to do. In time (and after I added dual exhaust) I didn't feel like I had enough volume especially at highway speeds. I almost never used my back seat so having a single sub was no biggie. My wife wasn't having it, so to convince her I had to try to set something up on the cheap. I sold the hideaway, bought an open box Kenwood KAC 5001PS, 1200 watt wiring kit from box store, enclosure from box store, tried a kicker Comp R 2ohm DVC (so it was running at 4ohms 300W) didn't like to stress my amp that much, exchanged it for the Alpine type S and am running it 2ohms @ 500W, bass boost all the way down, gain at approx 3/4. way more output and way cleaner than the kicker comp R (it was underpowered though). I had to turn the gain down for hip hop, does techno very well, rock/metal kicks sound nice and punchy (I have to adjust my EQ for each genre just a tad). I did this sub for very cheap and it has exceeded my expectations. With a topnotch enclosure and much better amp than mine, or a dual setup I'm sure the SPL guys could enjoy this sub as well. Thumbs up!
Pros: -Great sound quality -Clean design -DVC abilities -Pretty efficient
Cons: -Price (I think they could have done these for less -Getting the Wife to sign off on anything car audio related
This sub can take a lot of power. Sound and feel are very nice.
Pros: I use this sub in the house driving it with a 1500 watt sun fire amp and it takes it.
Awesome sounding sub couldn't ask for anything better
Excellent subwoofer for its price range! Currently is installed in my s2000 and is more than powerful enough to make it though a sheet metal wall and thick plastic trim. Is powered by a 500rms bazooka amp. Sound is clear and very crisp. Clean and simple appearance makes it match every interior which is what I wanted. As well the bezel hides the mounting screws giving it a smooth trim edge. Huge improvement over my previous bazooka 1204's. Only minor complaint is the rubber bezel. It could be easily damaged during installation but if your careful there's no need to worry. Overall cannot be more pleased with the alpine. Perfect option for under $200.
Pros: Clean appearance High build quality Crisp clear sound Very powerful when operated near the top of the RMS range. Bezel hides the mounting screws
Cons: Rubber bezel could be damaged during install
This sub is absolutely AMAZING! This sub shakes my whole car even turned up a 1/4 and when its all the way up i'm able to shake the cars next to me. I'm only feeding it 100 watts also since if i hooked it up to my sound ordanance m1500 it would probably destroy my battery.. So once i get a new battery it won't be thirsty anymore. I can't thank Crutchfield enough and alpine!! I will keep buying stuff from this website and will only buy from Crutchfield!
Cons: Nothing yet!
These subs are awesome..I purchased two 12 inch and are running them in a ported box along with a class d mono amp...can ya say thump! !!!
Pros: Priced right!!!
The best sub I've ever had. I heard it and immediately sold my 2 15 inch kicker squares to go get one with a ported bassworkx box and couldn't be happier.
Pros: Sounds like 2 15s
Cons: Not a single complaint
The bad reviews I read here sound like either improper amp match or improper amp gain settings. Do not let that discourage you. If you match it and set it up correctly it is amazing.
I love this sub. Even though, yes it is my first sub and yes, I am probably fanboying over it, It hits really hard. i have it paired with alpines MRV-500 amp and have the gain set to 2/3 and bass boost set to 9db. I have a convertible mustang so I had to make a fiberglass enclosure- roughly .85 cubes- and it sounds great. hits the lows and is very loud. My only complaint is that there a slight ruffly sound it makes when it hits the extremities- higher or lower notes, but only I notice it- none of my passengers do. And yes, i have shocked them when i reveal that it is only one sub. Anyways, i recommend it.
Pros: Loud, accurate, great bang for buck.
Cons: Slight ruffling when it hits the higher or lower notes (almost inaudible though)
I wanted to share my experience since I used to be very heavy in the Crank it up scene in the 80's-90's. I used to run Lanzar Pro subs with 90-93 db efficiency. These are 86db. You have to double the watts to add 3 db so a more efficient sub takes less power to get the same db as cheaper subs. This is a good tight well controlled sub in an enclosed box of 1.2 ft2. I am running 1 with a late 80's ZED audio made Autotek 7050BTS. This is a high current 22w x 2 amp that puts out around 150w at 2 ohm ( how I have it ) and 250w at 1 ohm. In my 4 door with the box in the trunk I hit 120db at the drivers seat with 1 sub. A pro sub would be 90+ db efficient but for the money and the low cost of amps now this is a very well controlled sub for rock, classical. jazz, and somewhat for rap. Would be best if ported for Rap but Chicago and all the other 80's groups sound great with it.( I'm old ) Oh, I played Boom Boom Pow to get the spl. I got beat by 2 db by cars with dual subs and/or 500-1000 watt amps. Well worth the money for tight controlled sound. There may be better for pure loudness but my systems have always been about SQ and not all about loudness.
Pros: Quality sound Tight base in sealed box
Cons: wish was more efficient 86db not good enough
I bought this sub to replace 2-10" subs I had before and it was well worth it! I have an Alpine MRP-M500 amp powering my 12" and it's perfect! I bought the 4 Ohm dual voice coil because I already had the amp an didn't want to buy a new one and I could just bridge the 12" from 4ohms to 2ohm which is perfect case now I can use all 500watts if I want and don't have to worry about overpowering the amp or sub.
Recently bought an alpine type s and wow does it pound. I decided to put it in a sealed box since i never used one before and let me tell you it sound incredible. I bought an audiopipe 1500 since i was on a budget and it does the job. One big thing though, i have all the settings and gains set really low because i dont kknow if the sub would accept all the 1500 watts. Sounds really good either way.
Pros: Looks very sleek with the black cone. Small and versatile. Version of older type r. Good for people on a budget.
Cons: None so far.
Only using a 500 watt alpine amp turned up half way with the eq down and I smelled one of the voice coils but it still hits pretty good for a single 12, I would buy atleast a 700 rms amp and turn it down.
Pros: Looks build quality
Cons: Price, theres a lot better subs from the smaller guys that are every bit as good if not better for a lot less.
Excellent but, got them like 6 months ago and they are great.
Pros: All around good, sounds is great
Sounds nice powered by a 500 watt alpine amp. Would defanitly buy again
i have two of these in my car in a ported box on a 1200 watt hifonics amp and every body tells me to turn them down when they are not even 3/4 the way to full power they will blow your socks off.
Cons: little bit cheap on the terminals on the sub but they work fine
bought one of these from my local car audio dealer. Powered by a powerbass 400.2 watt amp (with 800 watts peak power) and its inside a ported box. This sub does a really nice job and reallyyy bumps on songs with good bass. it rattles my change in my cup holder on some songs. If you got two these things would be devastating! but just one works too im pretty happy with it.
everything is great on this sub except for the outside of the cone where the ruffles are. It makes it sound vibrating and not very good
I have one type s in a ported box. It's powered by a Polk 880 mono block amp, and an alpine Ina-w900bt running everything. This sub is an incredible value 150 bucks for near type r performance. I am impressed and now an alpine fan for life.
Pros: Inexpensive and great performance.
Cons: I wish I would have bought two!

Kevlar Reinforced Pulp Cone: This Alpine Type-S subwoofer uses a parabolic cone structure, with a Kevlar reinforced pulp cone and a Poly-Mica dust cap. Kevlar adds strength and tear resistance to the woofer cone while maintaining the benefits of a pulp cone design. The oversized, inverted poly-mica dust cap increases rigidity and virtually eliminates cone distortion at extreme volume levels.
HAMRS: The woofer features a High Amplitude Multi Roll Surround (HAMRS), made of Santoprene, that allows a large linear excursion and greater SPL. The HAMRS design allows extreme excursions without sacrificing valuable cone area.
Progressive Spider: The progressive Conex spider has reinforced layer tinsel leads to ensure reliable and consistent control of the tinsel leads and eliminate any mechanical noise or interference often seen in high excursion cone designs.
Compound Radius Curve Pole Geometry: Alpine's Patented Compound Radius Curve pole geometry ensures a symmetrical magnetic field, while optimizing flux density to reduce distortion and further improve power handling and output.
Oversized Voice Coil: The oversized (65mm), high-temperature, 5-layer dual voice coils offer power handling up to 500W RMS / 1500W Peak (250 watts RMS per coil).
Dual Voice Coils: For system flexibility, the woofer has two 4-ohm voice coils. When the voice coils are wired in parallel, the woofer presents a 2-ohm load. When the voice coils are wired in series, the woofer presents an 8-ohm load.
Spring Terminals: The spring post terminals are all located on one side of the woofer. The terminals will accept pin connectors, single banana plugs, or bare wire up to 8 gauge.
Jumpers: Included with the woofer are two voice coil terminal jumpers. These jumpers allow you to easily wire the voice coils in parallel (for a 2-ohm load) or series (for an 8-ohm load).
Sealed Box: Alpine recommends a sealed enclosure with an internal volume between 0.71 and 1.06 cubic feet, with an ideal volume of 0.9 cubic feet. Sealed enclosures provide the most control over a woofer, will handle a lot of power, and provide accurate sonic reproduction, making them suitable to all types of music.
Ported Box Volume: The recommended ported box volume ranges from 1.06 to 1.56 cubic feet, with the ideal size being 1.46 cubic feet, using a slot port measuring 12.5" (W) x 1" (H) x 18" (L).
Thanks for your question. For information on selecting the best amp for your subs I would recommend reaching out to an Advisor by phone (1-800-324-9695) or online chat. They will be able to help determine the differences between the amp models and help you make the best choice for your system. [ Krissy Nov 14, 2014 ] Staff
yes [ rudy Nov 14, 2014 ]
yes. you need a good amp for these aswell. you might be able to fit it in your cars sub space in the back (if you have one), but i doubt it could fit a twelve And i don't think factory subwoofer amps could put enough power into it. [ Todd M. Nov 13, 2014 ]
Yes, to optimize the sound properly the sub needs to be in a box [ BRAD P Nov 12, 2014 ]
Yes. I just had the local place that was installing it put it in a box. Also recommend you secure it in the back so it won't slide around back there. [ AARON C Nov 12, 2014 ]
Thanks for your question. For information on comparing two or more models I would recommend reaching out to an Advisor by phone (1-800-324-9695) or online chat.

hi I have a alpine mrp m500 want to know if sws 12d4 is ok for my amp? thanks [ hector Feb 18, 2014 ]
It depends on what type of amp you have, you either wire it in series or parallel based on your ohm rating of your amp and subwoofer. There is a wiring diagram chart on crutchfield. [ STEPHEN Dec 27, 2013 ]
