Celebrate powerful low-frequency performance with the Ground Zero 30th Anniversary GZW 12-30A, a high-output 12 inch SPL subwoofer designed for serious bass enthusiasts. Built for demanding sound systems, this model combines a reinforced paper cone, solid aluminium cast basket, and a 75 mm copper voice coil to deliver strong, controlled output with impressive durability. As part of the Ground Zero 30th Anniversary series, it reflects the brand's commitment to premium engineering and competition-grade bass performance.

With 1500W RMS power handling and a maximum power rating of 3500W, the GZW 12-30A is made for large-scale SPL applications where impact and reliability matter. Its dual 2 ohm voice coil configuration provides flexible wiring options for custom amplifier setups, while the 85 dB sensitivity and long stroke suspension help maximise output across the low end. The 12 inch format, 284 mm mounting diameter, and 198 mm mounting depth make it a strong option for properly designed enclosures, including sealed box applications around 1 cu/ft or 28 litres.

Engineered for deep bass response and high excursion, this subwoofer features a 45 mm Xmax, 26.5 Hz resonance frequency, and a 2-layer Polycot spider for stable movement under heavy load. Whether you are building a high-pressure sound system or upgrading a performance-oriented audio setup, the GZW 12-30A delivers the structure, power, and control expected from a premium SPL driver.
