AUDIOFROG GB10D2 10″ (250 MM) AUDIOPHILE GRADE AUTOMOTIVE SUBWOOFER

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 GB10D2 includes a vented, cast aluminum basket, dual 2 ohm voice coils and a convenient switch to select a 1 ohm or 4 ohm configuration.
