Klippel® optimization and a long-throw compound surround ensure stable operation and high linearity, while the die-cast aluminum basket with excellent ventilation guarantees effective cooling and long-term reliability.

Specifications of the Ground Zero Nuclear series

The Nuclear series from Ground Zero represents a balanced combination of top-tier products for high-quality listening (SQ) and powerful components for competition applications with high acoustic pressure (SPL).
