About the Product
Alpine is proud to announce the introduction of the new R-Series Subwoofer lineup that is built off the highly esteemed Type R platform. With select key design and build improvements, the R-Series Subwoofer is able to output more of that deep bass extension and control that the Type-R is known for.
The new fourth-generation Type-S subwoofers have undergone a revolutionary redesign, leaning heavily on patented technologies developed for the Type-R series. The result is a subwoofer that is so good we had to redesign the Type-R. These new subwoofers redefine the expectations in their class. Altogether, they offer significantly improved output, deeper bass extension, more control and even greater power handling.

What customers say about "Size & Weight"
Alpine Type R (R-W12D2) 12 Inch 2250 Watt Max 2 Ohm Round Car Audio Subwoofer
  • The box size for a 12 is relatively small but this thing will knock the ole socks off
  • I love that Alpine recommends the box size and type which eliminated the costly and timely need for trial and error.

What customers say about "Audio"
Alpine Type R (R-W12D2) 12 Inch 2250 Watt Max 2 Ohm Round Car Audio Subwoofer
  • Have had these for about a year and they still are great. Running them at 700RMS Each and it is incredibly loud. Would recommend these to everyone
  • This sub hits so low, I had an mtx thunder 4500 before this and this sub hands down is wayyyyyy better, I give it 700 watts rms and it shakes my whole car. For any price alpine cannot be beat in quality.
  • I have one of these running 700 watts rms and it blows everything out of the water. It hits notes my old Kicker CVR could only dream of hitting. The notes are so clear and smooth too
  • I have had two of these at seperate times...they both blew at 100 rms so i would reccomend only feeding then 800 rms or less. but they look very nice and i would buy again if they were on sale and i was looking for some more 12's
  • 750 Watts ... 15 Hour break in ... Clean Deep Bass. Ported 1.86 cubic feet
Alpine Type-S (SWS-12D2) 12" Dual 2-Ohm 500W RMS Car Subwoofer
  • I fried this sub with too much power. Sounded incredible though. Even to moment of departure :{ Keep this at 500w rms or lower
  • Wow, Just wow. This sub in a ported 1.5 cubic ft enclosure with a 3" x 8.5" long port tuned at 35 HZ hits hard. I am running 1000Watts RMS to this sub at 1 ohm. It handles the power beautifully and is very controlled.
  • Can't lose with Alpine. I'm running this with a 500 watt rms alpine amp.
  • I am powering this sub and my system with a JL Audio Slash series 500/5 and it preforms flawlessly. This sub will hit hard if needed, but sounds just as good with classical or jazz music. Very clean, solid lows.
  • I would not recommend this sub with less than 400 watts RMS. They are power hungry but if you feed it,it will reward you. I am powering this with a Soundstream Picasso Nano PN1.1000D.
  • Speakers were ok sounding but not quite as good as i hoped. Had 2 of these hooked up to an 1100 RMS alpine amp halfway up so it was hitting a little above the 1000 RMS that 2 of these are and they burnt themselves out in less than a month. Maybe they are good lower than their RMS
