Wat is a stroker ...]?

The Stroker exemplifies the tradition of the original Stroker. It�s dual spider design maintains linearity and stabilizes the speaker in extreme excursion conditions. The new Stroker epitomizes high-output, high-performance subwoofers and has a linear operating range to an incredible 29mm in each direction.

The Stroker can handle an amazing 2000 watts of power and provide more than two inches of peak � peak excursion when loaded into a �High-Q� enclosure. Because of the extreme power capacity, a unique aluminum basket was designed to increase efficiency, thermal power handling and reduce thermal compression. The voice coil is placed directly next to an aluminum heat sink that is integrated into the basket. The basket design employs external heat sink fins to help dissipate heat pulled away from the voice coil to the outside of the enclosure. In a sealed enclosure, this reduces the internal ambient heat by as much as 50%. Another technology breakthrough is the unique motor geometry, which allows extremely high excursions with shorter voice coils than conventional designs. This results in a woofer with extremely high SPL capability while maintaining high sensitivity.

Service issues were addressed by developing a field replacement cone assembly. The removable spider tower and alignment access holes in the back plate, combine to allow simple field replacement procedure. Further enhancing the process is the unique Axial Surround Clamping System, which allows the cone assembly to be replaced without glue and provides a larger surface area for increased SPL.
