Wiring wizard & port computer

Use our wiring wizard for simple wiring of speakers and subwoofers! The correct connection is important for your amplifier! Low-impedance operation can damage the amplifier! The data sheet shows you which connection the respective amplifier is designed for!

Our port calculator shows you which tuning your enclosure has! The net volume is always particularly important here; calculate the pure chamber of the subwoofer beforehand to arrive at the correct result. The net volume is calculated minus all displacements and is important when designing the enclosure.

The Rockford Fosgate Prime R2 Series offers powerful bass reproduction, high-quality materials, and flexible installation options at an attractive price-to-performance ratio. The 25 cm (10") R2D2-10 and R2D4-10 subwoofers feature a durable, mica-reinforced polypropylene cone and a generously sized 50-mm dual voice coil for reliable bass performance.

The sturdy steel basket with integrated ventilation beneath the centering spider promotes effective heat dissipation and ensures reliable operation even under heavy loads. Thanks to the dual voice coil, the subwoofers can be flexibly adapted to different amplifier impedances. Both models are suitable for both sealed and bass-reflex enclosures.
