General Features:

  • 12" Fifth-Generation Type-R Series Car Subwoofer
  • Power Handling:
    • Peak: 2250 watts
    • RMS: 250-750 watts
    RMS Notification: The objective rated wattage for the SWR-12D4 Subwoofer is 750W RMS. Alpine historically labeled this subwoofer as "up to" 1000W RMS so it would line up versus other brands that at times unscrupulously overrated their subwoofers. The new R-W12D4 from Alpine (which we can upgrade you to for a limited time) is built on an improved platform, with a more efficient design and will outperform the SWR-12D4 across the board. Enjoy!

Great Products; Great Prices

I've had previous Alpine Type R 12" speakers, and purchasing their most recent version from Sonic Electronix was good move! Great product for way less than you'll pay anywhere else. I'm consistently impressed with Sonic Electronix 's product selection and shockingly low prices. I will continue to support and recommended this Company.

question

I want to ask someone who really have owned this new type R and owned a type x also, I had bought a type R in 2009 and it wasn't loud so I changed to a type x, I am wondering if this new Type R is the same as a Type X since as they discontinued the Type X?

For clean tight low end response

This is definately the sub for the true audiophile that is not looking to spend a fortune, but demands the best in sound quality and true clean bass respone, this is a great purchase and a well built driver.

the hardest hitting subs ive owned

I have had dual Rockford fosgate p3 12s and dual hifonics Brutus sq 12s and neither compare to these sub's. You can not beat the price and quality of sub's. Must buy!!!!!! Only issue for me is the extra rubber that hides screw's. It would stay on so I didn't use it but they still look and sound beautiful in ground shaker bandpass box.

Don't be fooled

Alpine say's that this sub will run 1000 watts. Don't be fooled I Bought one and blew and 3 months after the break in period I blew a voice coil. I had it hooked up to a JL Audio 1000/1 V2 slash series amp. The sub is worth the money if you're not gonna run 1000 watts to it but if you are you might want to go with the type x.

Alpine type R

This is a great subwoofer, for 159$ this and the RE audio line, are the best for the price. I chose alpine however for the significant power boost. Just so you guys know you really don't have to worry about power, just watch your gains. I'm giving mine 1200 rms and it takes it like a beast. Highly recommend this in a sealed box for rock, and really it gets to a great volume in a sealed, but ported for sure if you're into volume and you will only need one of these.

Sub Gone Bad

Purchased this sub about 6 months ago and installed it in a ported box and it sounded great until the cone came unglued and now I am having to have it repaired. I am hoping after the repairs are complete it will sound as good as it did the first 6 months and that it will last a lot longer this time.
