Rockford Fosgate's Prime R2 shallow-mount subs deliver satisfying bass even in smaller cars where space is tight. A special elevated motor structure lets these low-profile subs work in extremely compact enclosures, while still handling plenty of power.

The R2SD2-10 sub features a 10" mica-injected polypropylene cone that works with a high-density poly-foam surround to punch out fat, deep notes. This shallow-mount workhorse will handle up to 200 watts RMS, with a mounting depth of only 3-1/2". Rockford Fosgate stitches the tinsel leads that carry the signal to the voice coils directly into the cone, so they'll hang tough through heavy use. The stamped solid-steel frame offers the same venting found in standard-mount Rockford Fosgate subs to keep this sub running cool.

Dual 2-ohm voice coils allow you to wire this sub for 1- or 4-ohm impedance, giving you more flexibility in setting up your system. Rockford Fosgate optimizes this Prime sub for both sealed and ported enclosures so you can choose the type of bass you want in your ride.

Product Research

Features

Shallow Mount Design: The Rockford Fosgate Prime R2 Shallow Subwoofer is designed and engineered with a much smaller motor assembly which reduces the overall depth of the woofer allowing it to fit in shallower enclosures and tighter locations of your vehicle.

Dual 2-ohm Voice Coils: This woofer features dual 2-ohm voice coils to offer wiring flexibility. When the voice coils are wired in parallel the woofer presents a 1-ohm load, when wired in series it presents a 4-ohm load.

Spring Post Assembly: The woofer features compression input terminals with attached 16-gauge stitched tinsel lead wires. The nickel plated spring posts will accept pin connectors, single banana plugs, and bare wire up to 12-gauge.

Sealed Box Volume: Rockford Fosgate recommends a sealed enclosure with an optimum internal volume of 0.7 cubic feet (from 0.5 to 0.75 cubic feet is acceptable). Sealed enclosures provide the most control over a woofer, will handle a lot of power, and provide accurate sonic reproduction, making them suitable to all types of music.

Vented Box Volume: Rockford Fosgate recommends a vented enclosure with an internal volume of 1.4 cubic feet using a 4" diameter x 13.7" long port tube; this yields a tuning frequency of 42 Hz. Ported (or vented) enclosures typically provide better overall efficiency than sealed so they are suitable for use with smaller amplifiers, giving you more bass output from less power. However, this efficiency comes at the expense of very low frequency output (below 35 Hz).

Does this need an enclosed box?

This subwoofer does require an enclosure. It is not rated for free-air use.

zachary Sep 01, 2022 (Staff)

Would this produce much bass with 60 watts @ 2ohms going into each voice coil in a sealed enclosure?

Everyone's idea of just how much bass is enough varies so we have advisors that can be reached by calling 1-800-324-9695 who can discuss your goals and preferences to check

jason Aug 07, 2021 (Staff)

Yes it would produce enough bass unless you want to go to the ear doctor down the road

Hi Chad, I am sorry, but Rockford does not offer a grille for the R2SD2-10 subwoofer.

What is the best kind of box to use to put 2 of these in a single cab dodge dakota for the most bass and best sound quality?

nic Nov 30, 2014

2 answers

I used this in a sealed box. I also am powering with an amp that is way to much wattage. The gain turned down about half. Depending on your power situation and of course style of music will depend on application. If underpowered, use ported boxes.

david Dec 02, 2014

I built a custom box for my f-150 and only placed a single sub beacuse I did not want the bass to over power the cab. The box is 12"w 6"t 14L. I would recommend two smaller boxes instead of one long dual sub box so the air flow does not get wasted inside the box all the sound will travel from the box into the cab with two single enclosures. If you do need to make or purchase a single dual sub box make sure it has a vent tube in the center so you can get more then just one frequency of bass and all around lows. You can find plenty of diagrams online if you want to make one or you can also lok up ones made specificaly for your truck. With a single cab it might be easier to build what you want for space and location. Hope that helps and congrats on the new system.

Audition speakers before you buy

SpeakerCompare simulates the sound of home and car speakers through your headphones. It lets you compare sonic characteristics between speakers so that you can make a more informed shopping decision.

Why selecting your headphones is important

SpeakerCompare tailors your listening experience to the exact headphones you have, so that what you hear is comparable to auditioning speakers side-by-side in person. Knowing which model headphones you’re using lets us remove any sonic coloring from your experience.

Two different listening modes

In an actual listening room, you'd find that some speakers play louder than others when fed the same amount of power. In equal power mode, you'll hear these differences in loudness as they naturally occur between speakers.

In equal volume mode, we've made the loudness of each speaker about the same. This gives you a more direct comparison of subtle voicing differences between speakers.

Nothing beats listening to speakers in your space

SpeakerCompare gives you a sense of the sonic differences. But performance in the real world is affected by the acoustics of your car or home, your choice of amplification, and your source material. We still believe that the gold standard for auditioning speakers is hearing them in your own environment — that’s why we offer a 60-day money-back guarantee.

Our Listening Kit

To help you choose the right speakers, we recommend using Crutchfield’s SpeakerCompare Listening Kit. It includes a pair of studio-quality headphones, and a guide to getting the most out of your session, and a few other necessary items. We’ve carefully chosen the components of this kit to ensure a crystal-clear listening experience. It’s available for a nominal rental fee, and includes a $25 Crutchfield merchandise credit.
