Alpine SWR-1242D

wow

ok to start off. I like to play my music hard and loud. I put these through a lot and there still going. I have them in a slot ported box about 3cu ft.
I have two of them 4ohm wired parallel at 1 ohm.

great!!!

for the price this subwoofer is really hard to beat. great sq and has some good spl too. hits the lows very well without any distortion. this is one of my favorites.

Great SUB

Got one of these hooked up in my Accord
with a 1000 watt Kenwood amp, a lot of power
would recommend this product.

Great Sub

I've Had this sub for a year and its been great so far no problems to speak of. About to get a second one cant wait.

Amazing Sub

Great quality subwoofer. I have this hooked up to a RF Prime amp and it hits hard. Have yet to see any Cons with this sub. Shakes the whole car but sound is definitely high quality as well.

Great sound but one of mine already blew :(

Bought these 6 months ago and had them professionally installed. Sound great but one of them already blew. Definitely a disappointment there.

sounds good in my single cab

I have 2 12" dual 4 ohm in my truck in a custom box I made, internally braces and sealed all the way around. Even though this box was made to specs and solid as a rock I wish they could go a little deeper. But for what I payed these are great and they still hit deep enough to shake windows when I pull up somewhere. Overall this woofer is very versatile and sound good when in the right box.

Type R

I bought this sub about 6 months ago. At first, I had it running on the stock amp (about 60w rms) in my Cobalt, enclosed in a 1.25 ft^3 sealed box. As one could imagine, it just wasn't loud enough, so I bought a ported box (also from this site) and added a Fosgate amp. I am a guy who enjoys his low notes, and the Type R delivers great low end response! Overall this is a quality product (as is everything Alpine has made) and Sonic is the best site to buy from. I would highly recommend this sub! Combine it with a good 500w amp in a ported box, and you will NOT be sorry.

Satisfied

I have one of these and people think I have much more. Great for inside system, decent if you want to heard coming. but I prob got 470rms or so going to it, not sure how much it can take. Good value. I think 2 of these with 1000rms pushing it would be plenty

downsized......... not really

I bought this sub to save some space in my trunk. I have been a two 12s guy for as long as I can remember and was convinced that one sub just could not cut it. I was so wrong. This sub with a pdx 1.600 and a 1.8 ported box kills it. There may be better speakers out there but for the price there is no comparison. Price is all I can say. On and off car audio guy for ten years. Anyway I almost wanna pick up another one just in case my GF ever wants a sub but I'm too cheap for that. Quality bargain hunters search no further.

Greatest Investment Ever.

OMG! Ive been in the car audio game for two years. Over the years ive had everything from cheap to expensive, one to four subs, ported sealed all of that... Finally decided play with the big boys and get nothing but the best.

Super Duper Bass. I have just one in a ported box paired with the Rockford Fosgate Prime R500-1. Perfect Combination. If U Only Want One Get This Pair! Wont B Disappointed.

a good all around sub

The alpine type R is a sub that nobody could be disappointed with. The type R will play very, very loud and still remain clear. I have a civic with the sub bumping i am unable to light a lighter in the car because of the air vibrating (I only have one), I would recommend this sub to anybody.

Loud

I have one of these in a vented enclosure and it bumps so hard!

Alpine type r great sound for great price

got this a few months ago for a good price. lows on this subs is clear and deep. running it with alpine cda117 head unit and alpine mrp-m500 mono amp at a stable 2ohms. the thing about this sub is you can't just go out and buy a cheap prefab box, you need to get a box built to its specs to get the full use out of the sub otherwise your system will sound like crap and you can even ruin the sub. spent $250 just to have the box built to its specs. overall great sound for great price.

Great Sub

Best 12" out there in my opinion. Pair it with the right amp and box and you have more than you need without it getting sloppy.
