Audiofrog 12" GB Series Dual 4 Ohm Mobile Subwoofer - GB12D4
GB Series subwoofers are designed for high power handling and optimized to provide superior low frequency extension from a wide range of sealed and vented enclosures. A copper inductance-reducing pole piece cap also reduces distortion and extends the range of flat response well into the midbass. The GB12D4 includes a vented, cast aluminum basket, dual 4 ohm voice coils and a convenient switch to select a 2 ohm or 8 ohm configuration.
