Maximize your vehicle's acoustic potential without losing precious cargo room with the Massive Audio GTS12, a high-performance shallow mount subwoofer specifically engineered for ultra-tight installations. Featuring a remarkably slim 3.24 inch mounting depth, this 12 inch subwoofer is the definitive solution for behind-the-seat truck enclosures, under-seat boxes, and custom compact SUV side panels. While most thin speakers sacrifice low-end impact, the GTS12 delivers the resonant, hard-hitting car bass that audiophiles expect, handling a solid 350 Watts RMS and 600W Peak. It is the ultimate upgrade for those seeking a professional car audio experience in a space-saving package. The superior build quality of the GTS12 ensures it stands out among traditional car audio subwoofers. It features a rugged injection-molded polypropylene (PP) cone paired with a custom high-pressed roll foam surround. This design allows for a 9mm X-max that moves significant air for deep, atmospheric lows despite its low profile. At the heart of this compact subwoofer is an impressive 3 inch high-temperature dual 4-ohm voice coil—significantly larger than most shallow competitors—wound on an aluminum former for superior heat dissipation. Anchored by a heavy-gauge steel basket and a 50oz high-flux Y35 magnet, the GTS12 provides the motor strength required for accurate and powerful car audio reproduction. As a passive subwoofer, the GTS12 gives you the freedom to pair it with high-quality external amplifiers for a far more professional soundstage. It comes equipped with gold-plated nickel push terminals and a poly-cotton spider for long-term reliability. Whether building a custom truck subwoofer setup or needing a 12 inch speaker that fits where space is limited, the Massive Audio GTS12 offers the perfect blend of slim design and massive performance.
