Alpine Type-R SWR-1242D Subwoofer

Not Available

Product Details


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.

Nothing But Trouble

Strengths: Loud/Low Bass

Weakness: Don't last long

3 years and counting.........

Strengths: Solid, Deep, and Clean Bass.....

Weakness: None.......................................

I have always relied on Alpine head units, but never on a speaker, until now. I was a JL sub fan until I purchased these two 12" type R's, pushed by an Alpine PDX-1000 and these things hit. They are currently in my 2001 Suburban, and that was a problem. With the open cabin I had to turn the amp volume all the way down so I could hear the highs, but it still shook the neighbors house. Added type R...

Hit hard and sound GOOD

Strengths: 500 watt RMS hits like 1kwatt RMS subs. will not blow(it is alpine only expect the best)

Weakness: none

I started out my system with two Type-E 12" subs and they hit harder then other systems in town with a whole 500 watts running to the two. So i went up a few notches bought 2 type r's 2 PDX 600.1 and a Kinetik Power Cell (800 version). Well basically no one laughs at me driving my 1984 Subaru Wagon around town because they hear me coming before they see me coming. I have been told i will lose my...
