G12D4 12″ (300MM) PERFORMANCE GRADE AUTOMOTIVE SUBWOOFER
Designed great-sounding low frequency reproduction with amplifier power up to 600 watts RMS, the G-Series subwoofers have been engineered to provide the same frequency response in the same sealed and vented enclosures as the GS and GB Series subwoofers.
G Series subs feature double stacked ferrite magnets and an extended polepiece for magnetic symmetry above and below the gap.
They also feature the same rigid treated paper cone and rubber surround as the GS and GB Series subs. Gold-plated 5-way binding posts make connection simple. The G12D4 includes dual 4-ohm voice coils for system design flexibility for plans that include one or multiple subs.
