Ground Zero GZUW 8SQ-D2
The revamped Ground Zero Uranium SQ range is designed to deliver excellent sound quality at a very reasonable price. These drivers don't set SPL records, but they deliver natural, accurate and low-end bass reproduction that is a pleasure to listen to with all types of music. They work in all types of enclosures, but this new driver is an excellent fit for a small sealed enclosure or a low-tuned reflex enclosure.
The perfect choice if you want an affordable element that works great in a small space, and doesn't require crazy amounts of power to operate properly.
