Massive Audio Launches the GTR84: Big Bass in a Long Throw 8-Inch Design

LOS ANGELES, CA (04.15.25) – Massive Audio proudly introduces the GTR84, a compact 8-inch subwoofer built for car audio enthusiasts who want big sound in tight spaces. With 600 watts RMS and 800 watts peak power, the GTR84 is engineered to deliver powerful, clean, and dynamic bass—making it the ultimate low-frequency upgrade for small to mid-sized builds.

The GTR84 sets a new benchmark in Long Throw subwoofer performance, backed by five precision-engineered features:

  • Heavy-Gauge Steel Basket with Long Throw T Yoke
  • The rugged steel basket forms the structural backbone of the subwoofer, providing a rigid and vibration-resistant foundation while allowing for longer throw.
  • Dual Stacked High Flux Y30 120oz Strontium Ferrite Magnets
  • With two stacked 120oz magnets made from Y30-grade Strontium Ferrite, the GTR84 delivers exceptional magnetic strength. This setup ensures tight cone control, enhanced efficiency, and thunderous bass output that remains clean and punchy at all volumes.
  • Dual Impedance / 2″ High-Temperature American Copper Voice Coil The high-temp 2″ voice coil is built to handle intense power without overheating, thanks in part to premium wire sourced from the USA. Its dual 4-ohm configuration offers versatile wiring options, allowing installers to fine-tune impedance for system compatibility and maximum amplifier performance.
  • Custom High-Roll Foam Surround with MASSIVE Logo
  • Designed for extended excursion, the high-roll foam surround enables the cone to move more air—translating directly into deeper bass. While the thin design maximizes the woofers cone area for added air movement and lower frequency response.
  • Textured Non-Pressed Pulp Cone Reinforced with Resin
  • Combining the warmth of traditional pulp with the structural reinforcement of resin, the cone delivers responsive, low-distortion bass across all listening levels. Its non-pressed texture adds sonic character while maintaining the rigidity needed for high-output accuracy.
