Ground Zero GZRW 300SPL Pink
The cast frame, High-roll sandwich top suspension and sturdy magnet are the first things you notice about this element from the top. A closer look reveals more details that make the element such a functional unit. The reinforced paper cone with a really sturdy dust cup is attached to the top suspension with double stitching in addition to gluing. The voice coil is ventilated both through a tunnel in the center post and through ventilation holes in the frame. The voice coil is 3″ in size and is wound from OFC copper wire. Spring-loaded terminals keep the cables in place even in the toughest of jamming, and the conductors wound inside the bottom suspension can withstand even rough motions.
Not all good things are visible on the surface, and one of the most important is the Klippel optimization performed by Ground Zero. The optimization device allows us to monitor the operation and temperatures of all parts during a 10-hour long test. In testing, the element's power ratings are exceeded by up to four times. The purpose of this optimization is to find the weak points of the prototypes and make them better for the production model.
