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 GB10D4 includes a vented, cast aluminum basket, dual 4 ohm voice coils and a convenient switch to select a 2 ohm or 8 ohm configuration.
