The Rockford Fosgate Prime R2D4-10 is built for people who want solid, dependable bass without overcomplicating their setup. With CEA-2031 compliant power handling, it’s designed to take continuous power delivery, so you get tight, controlled low-end that stays consistent even during long listening sessions. No distortion, no falling apart when the volume climbs, just clean bass that feels right every time.
Thanks to its dual 4 Ohm voice coils, the R2D4-10 gives you the freedom to wire it the way your system needs. You can match it to different amplifier configurations depending on whether you’re chasing output or balance. That flexibility makes it easier to build a system that actually works with your setup instead of forcing you into one fixed configuration.


This subwoofer doesn’t just sound good, it’s built to last. The StampCast steel frame keeps everything locked in place for stable, distortion-free movement, even when the bass gets heavy. Inside, the mica injected polypropylene cone, anodized aluminum voice coil former, and spider venting all work together to manage heat and maintain durability, so it keeps performing strong even when pushed for long periods.

Great woofer for home theater system. Bass erupt and walls Shake.
I bought this product as an experiment. I put it in a ported box tuned to 32hz and pushed it with a Kicker mono 250. I was very impressed with the quality and sound that this product has. I would recommend this to anyone.
