The GT12 isn’t just a subwoofer, it’s a precision-engineered powerhouse built for serious bass lovers. From its bold aesthetics to its premium components, every element is designed to deliver deep, clean, and hard-hitting low frequencies with unmatched reliability.
At its core, the GT12 boasts a textured non-pressed pulp cone reinforced with resin for optimal rigidity and responsiveness. The cone is sewn with dual tight red stitching into a custom high-roll foam surround proudly embossed with the MASSIVE logo, ensuring both durability and style.
Beneath the surface, a heavy-gauge steel basket with an industrial-textured finish provides rock-solid stability, while dual stacked high-flux Y30 60oz strontium ferrite magnets generate incredible motor strength. The 2" high-temperature dual 4-ohm voice coil, made in the USA, ensures superior power handling and consistent performance even under intense demand.
The suspension system features a springy, high-quality spider and high-grade woven tinsel leads that connect to a custom terminal case with flexible pure copper wiring, guaranteeing efficient power transfer and long-term reliability.
With 500W RMS power handling, the GT12 delivers clean, powerful bass that stays tight even at high volume, perfect for anyone who demands both sound quality and performance.
