Ground Zero GZIB 200XBR-ACT

The predecessor models of the GZIB boxes were among the most successful on the market. It's no surprise, as they offered outstanding sound quality in their price range. The new models feature new subwoofers that have been optimized with Klippel technology. The drivers are characterized by a consistent impedance behavior, good sensitivity, and high power handling. These features ensure excellent sound quality and plenty of bass with very moderate amplifier power. New, better drivers also deserve a better enclosure. Previous enclosures were so good that it was challenging to improve them. The solution was to invent a new type of port. This enclosure uses an EFP connection (Enhanced Flow Port). It has a cross-section like an airport. This leads to significantly better airflow without side effects. More air through the channel means more bass! Despite the improved airflow in the same-sized enclosure, the tuning frequency remains the same as before. It delivers a very consistent bass response across the entire frequency range. The size of the connection is more than sufficient for the required amplifier power of this subwoofer. If you are looking for an active subwoofer that offers you good sound quality and plenty of bass, then you have come to the right place.
