XW Woofers utilize a T-shaped Pole design with dual shorting rings above and below the magnetic gap for a very stable magnetic field resulting in ultra-low distortion and low power compression
Large diameter voice coils enable massive sustained power handling. Voice coils are constructed of pure aluminum for light weight and improved thermal performance. The flat wound flat wire transfers heat more efficiently and allow the use of a smaller magnetic gap for a higher motor strength
Increases the volume of displacement of the subwoofer without limiting excursion is the true measure of output capability. Starting with the largest possible static displacement creates the largest dynamic displacement. (12″ Sd = 585 cm², 15″ = 960 cm²)
