GS Series subs feature 3″ (75mm) voice coils wound of fiberglass formers, massive 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 GB Series subs. Gold-plated 5-way binding posts make connection simple. The GS12D2 includes dual 2-ohm voice coils for system design flexibility for plans that include one or multiple subs.
