Variable Q (patent pending)- Kappa Perfect VQ Series subwoofers provide a patent-pending approach to adjusting Q. Kappa Perfect VQ woofers allow motor strength to be be varied using supplied polepiece inserts. Q adjustments allow the woofer to be optimized for a particular enclosure or application and provide the user with exceptional performance for several applications in a single enclosure.
Nitrile-butylene-rubber one-piece surround and gasket - This material provides an optimum blend of elasticity and internal damping. The large roll offers good long-throw linearity with the proper amount of control and stability at excursion limits.
Proprietary die-cast frame - This frame offers amplie rigidity to support the motor structure, and its vented architecture provides greater movement of air behind the cone and spider for maximum cooling.
Spider-integrated tinsel leads - These enhance reliability and eliminate audible tinsel lead slap.
Vented polepices - These provide additional cooling to the motor structure. The subwoofer''''''''s thermal capabilities are augmented, thus increasing power handling.
Magnesium Metal Matrix (M3D) woofer cones - This material is 20 times deader that aluminum, delivering superior stiffness and damping as compared to traditional cone materials. |
