Our take on the Rockford Fosgate Prime R1-1X12

by Bob Bihlmayer
Rockford Fosgate

Enclosed Subwoofers 101

An enclosed subwoofer is a box with a subwoofer already installed. The advantage to buying an enclosed sub is that the manufacturer made the sub, then designed and built the box as a perfect match, so you'll get the best possible performance. Every enclosed sub has a maximum RMS power handling rating, so pair it with an amp with a similar RMS power rating to get the best performance.

Maximum bass

Rockford Fosgate's Prime Series loaded sub enclosures fill your car with bass without emptying your bank account. These rugged sealed boxes feature 5/8"-thick medium-density fiberboard construction covered with a protective layer of heavy-duty black carpeting. And you can rely on Rockford Fosgate to create an enclosure that'll draw every ounce of bass out of its sub.

Handles up to 200 watts

The R1-1X12 sealed loaded enclosure comes with one Prime R1S4-12 12" sub. This 4-ohm sub handles up to 200 RMS watts and features a fiber-reinforced paper-pulp cone and compressed foam surround for big, booming bass.

At Crutchfield, you'll get detailed, accurate information that's hard to find elsewhere.

Features

Enclosure: The Rockford Fosgate Prime R1-1X12 features a sealed enclosure constructed of 5/8" MDF (Medium Density Fiberboard). The enclosure is covered with high density black carpeting. The sealed enclosure features high current compression terminals on the left side of the box (when facing the woofer). The enclosure's terminals will accommodate up to 12 AWG speaker wire. The enclosure's speaker terminals present a 4-ohm load to your amplifier.

Dimensions:

  • Width: 17-3/4"
  • Height: 14-3/8"
  • Depth (base): 12-1/2" (13-1/4" including the subwoofer)
  • Depth (top): 7-1/4" (8" including the subwoofer)

Woofer: The R1-1X12 enclosure is loaded with a single Rockford Fosgate Prime R1S4-12 subwoofer. The R1S4-12 is a 12-inch, 4-ohm single voice coil subwoofer with a fiber reinforced painted paper-pulp cone and compressed foam surround.

CEA-2031 Compliant: Power handling on the Rockford Fosgate Prime R1S4-12 subwoofer conforms to CEA-2031 industry standards. This means the subwoofer has the capacity to handle its rated power under continuous demand, not instantaneous power handling, that over time, can damage voice coils.

Rockford Fosgate Prime R1-1X12 Review

Crutchfield Customer Review (What's this?)
 
The subwoofer is awesome, it hits good and I got a great deal. I got it quick and I'm very happy with Crutchfrields's customer support, I didn't know I had to give them my number to confirm my order and an actual person called me and let me know so I wouldn't lose the product. They could of just never called me and I never would of gotten the product. I'm so thankful for that and it makes me want to come back to crutchfield again for future electronic purchases.
Pros:
The sub came in great packaging, it was easy to setup, and I had it bumpin in minutes. Crutchfield delivered it quick and was very helpful in the process. Crutchfield says it's the
Cons:
The only con is now I want to buy more stuff for my speaker system because my music sounds so good and that's a plus depending on how you look at it, but it's most definitely a con for my checkbook haha.

Crutchfield Customer Review (What's this?)
 
I have always been skeptical about just having one sub, not anymore. 150 watt amp with this sub is plenty, I find myself turning my sub level output from my receiver down so I don't drowned out the rest of my system with bass. This sub hits hard and the clean bass cords are clean and sound good. If your into subsonic lows it will numb your body and wiggle your brain.
Pros:
High quality, looks cool, simply to use.
Cons:
I think they could of spared a grill.
