Massive Audio GTS 12 Inch 600W D4 Ohm Slim Subwoofer & QBomb Sealed Downfire Box

Massive Audio GTS 12 Inch 600W D4 Ohm Slim Subwoofer & QBomb Sealed Downfire Box

Massive Audio GTS Series Subwoofers deliver powerful, low-frequency performance in a compact, shallow-mount design. With a mounting depth of just 3.24 inches, these 12" subs are engineered to fit tight spaces without sacrificing sound quality. Each unit features a durable injection-molded polypropylene (PP) cone paired with a custom high-pressed roll foam surround, allowing for impressive excursion and deep bass.

The cone assembly is securely bonded to a heavy-gauge steel basket and anchored to a shallow-mount, high-flux Y35 50oz Strontium ferrite magnet structure. At the heart of the subwoofer is a responsive poly-cotton spider with high-grade woven round tinsel leads, delivering clean power to gold-plated nickel push terminals.

A 3-inch high-temperature voice coil, wound on a high-impedance aluminum former, ensures efficient heat dissipation and reliable performance under pressure. Built to hit hard and stay cool, GTS Series subwoofers embody Massive Audio’s commitment to high performance and exceptional value.
