Why Choose the Soundstream R3-12?

Engineered for Earth-Shaking Bass

The R3-12 is built to handle massive wattage, making it ideal for high SPL car audio systems. With its oversized motor structure, the subwoofer delivers powerful low-end frequencies with precision. This isn’t your average 12-inch sub—it’s a high-performance subwoofer that competes with the best in its class.

Built to Last

The rigid die-cast aluminum basket ensures the structure remains steady during hard-hitting sessions, while the fiberglass-reinforced cone resists flexing and maintains sonic integrity. Its epoxy-treated construction adds extra strength to survive extreme vibrations and long hours of play.

Thermal Control

The vented backplate and aluminum voice coil former allow for efficient heat dissipation. That means cooler operation even under heavy loads—less risk of thermal shutdown, and more playtime without interruptions.

Versatile Sound Signature

Whether you're aiming for tight, punchy bass in a sealed enclosure or deep, boomy lows in a ported box, the R3-12 adapts. Its balanced blend of SPL and SQ makes it one of the most versatile 12-inch car subwoofers out there.
