The 600 Series subwoofers are not for the faint of BASS!
From the top down they are built for extreme sonic performance.
Heavy duty double stack magnet motors and long throw voice coils
handle the power while Power Tuned suspensions with EROM
surrounds and a progressive dual spider system keep the moving
parts linear and distortion free during high excursion play. The 600 Series
ubs work best in vented and multi order enclosures.
