Note: Unlike conventional DVC
subwoofers, the two sets of terminals
are configured so that both positive (+)
terminals are on one side of the frame
and both negative (–) terminals are on
the other side. GTi Series subwoofers are
shipped with terminal jumpers installed
which configure the two 6-ohm voice
coils in parallel for a 3-ohm load.
