Subwoofer Ground Zero GZW 12-30A

Subwoofer Ground Zero GZW 12-30A

The Ground Zero GZW 12-30A subwoofer was created as a special edition for the 30th anniversary of the Ground Zero brand and is designed exclusively for SPL applications, where maximum sound pressure, power endurance, and extreme mechanical stability are priorities. The construction is based on a solid aluminum cast basket combined with a reinforced paper cone, finished with a carbon dust cap. This material mix ensures a perfect balance between rigidity, low weight, and resistance to deformation at high outputs. The cone is surrounded by a long stroke U-surround for extreme excursion and high acoustic performance. The precise mechanics are ensured by a dual-layer spider made of Polycot material, which, along with a 75 mm (3") copper coil, allows precise movement control and high power handling. The entire construction has been optimized using Klippel® technology, ensuring minimal distortion even at performance limits and maximum efficiency in SPL competitions. The GZW 12-30A is a tribute to the technical development of the Ground Zero brand and an ideal choice for extreme sound enthusiasts seeking exceptional performance and character.
