Description
Big and bad and built for heavy-duty sound, Alpine's SWR-1242D 12" subwoofer delivers impact bass that you can hear and feel. Alpine has taken the best features from its previous SWR Series subs and added the hottest technology for ground-pounding power and superb accuracy.The pulp cone has been reinforced with Kevlar (the material used in bulletproof vests) for extra rigidity, so it won't buckle under hard play. A rubber surround helps to maximize cone travel for deep bass, while withstanding the decay that can destroy a speaker.

Strengths: great, clean, crisp sound and extremely powerful bass. clarity is unbelievable compared to anything else i have ever heard
Weakness: nuthin
I bought a whole alpine type r system. added the sub later and was shocked at how much of a differenece it made. I absolutely love alpine and trust them. Would love a type X system in my next car, but this type r system is better than any of my mates' systems.
Strengths: the bass is amazing and it was so easy to order from here
Weakness: none
price grabber is so great and easy to use im so glad i used them it made everything go smooth and fasT. The subwoofer is great and hit really hard and is said to be one of the best out there and price grabber mad it easy for me to find it at a cheap low price!!!!!!!!!!!!!!!!!!!!!!!!!!!!1
Strengths: Amazing bass, works well with single or multi channel amps, regardless of brand
Weakness: Can't find one
Started out with a large system. I put 2 12" Type-R's in the back of a modded out 05 Accord V6. At first, I couldn't believe the sound quality. Figured it would lose its crispness and suprising it didn't. Only problem I had with them in Accord was every 2 weeks had to take license plate off and straighten it because bass power would bend it. Totalled the Accord because of too much speed. I'm...
Strengths: Loud, Clear, Powerful, and Reasonably Priced. Need I say more?
Weakness: Just make sure you have the right amp and box. If you don't have a heavy duty alternator, then you might want to invest in a 1 Farad Capacitor.
This is pretty much the best sub you can get for under $300.oo. When you get this beast wired at two ohms to an amp with(600 Watts R.M.S.), and get it in a sealed ported box, then you will not believe the sound quality. People don't just hear me coming, they feel me coming. When my friends first got in my jeep they didn't believe that I only had one sub. This puppy will rattle your eyeballs! I...
Strengths: Power bass that people can feel, clear, are extremly strong and will never blow!
Weakness: NONE
I had my friend clock how far away he could hear me...it turns out I was 1 minutes 55 seconds away (around 2.1 miles) and he said he thought I was coming down the street the whole time!!!!!!!!!! Better then the Type X I had! LOUDEST SUB I have heard! I pull up to gas stations and have people in my car play them....some of the shelves in the store rattle....what else can I say My setup: 2 12"type...
Strengths: Very Very Clean
Weakness: None found (have had it for almost 2 years(
Absolutely crazy sub. I bought a complete Type R setup (6.5" component speakers, 5x9" speakers, Alpine Head the whole bit)and the Type R 12" sub with the alpine made sub box and wired it up to 4ohms to about 600watts. My friend has a complete Rockford fosgate set up with 2 12" P2s (he thinks its cool), and my ONE Type R, at 4Ohms 600watts eat his subs alive. Its hits harder, hits lower and most...
Strengths: Handles tons of power, and stays crystal clear
Weakness: Both sides of this product are works of art! Without a plexiglass box, you visually cant do this speaker justice.
I first bought the old versions of these back in 2001 and thought they were amazing. These new versions are even better!! I blew one after a few years of abuse and had to replace it with the updated version. I couldn't believe how much better the new ones sound compaired to the old ones! I have been using the SWR-1242Ds with my Memphis 1000D that I bought almost 10 years ago and it is one of the...
Strengths: LOUD, looks awesome
Weakness: none
This sub is insane. With enough power to it it can go unbelievably loud. I had my headunit turned about half way up and it was too much to handle, my ears are still ringing. I only have one because a friend of mine said that when he had two, it was too much bass, and i believe him now. If you want a good sub that won't be the same price of the car your putting it in, get this one, best for the...
Strengths: Solid Bass, Rattles the heck out of your car,
Weakness: NOne
Ive had this sub for about two months now and its already caused one of the tailights in my crx to break. Lucky for me i only bought one or else i dont think my car would run anymore. im running a 1700 watt amp thats runnin at 500 watt RMS one thing i would recommend is that you get a compacitor i still haven't bought one and everytime my sub hits at night my lights dim way down.. my friend just...

Haven't been able to blow em' up yet!
Strengths: Ribbed rubber surrounds, improved magnet cooling, kevlar reinforced cone and dual voice coils
Weakness: NONE
I bought a pair of these from a local dealer, I was told these speakers could take a beating. So I figured I would try them out, fully expecting them to blow up in a couple of days like every other sub I've tried in the last 6 months. But as it turns out, I was so overwhelmingly impressed by their performance, I just had to write this review. They are dual 2 ohm voice coil in a sealed, airtight...
