Focal RSB-300 Auditor 12″ Dual 4-Ohm Voice Coil Subwoofer 300W RMS 600W Max
Focal RSB-300 12″ Dual Voice Coil 4-Ohm Subwoofer
This double voice coil subwoofer benefits from a polypropylene cone with high rigidity, a crucial requirement in the low end for preventing distortion at very high volume.
Equipped with double ferrite magnets and 2” (50mm) voice coils, these subwoofers combine high sensitivity and high power handling.
The 2 x 4 Ohms double voice coil is the perfect finishing touch to the mechanical design. This allows the subwoofer to be wired in parallel under 2 Ohms in order to get the most from your amplifier.
