Massive Audio GTR Series 12" Subwoofer

Massive Audio GTR Series 12" Subwoofer pairs a double-stacked 120 oz high-flux Y30 magnet with a 2.5" dual 4-ohm voice coil for high-power, tightly controlled bass in a rugged 12-inch driver.

• Size: 12" — A standard 12-inch format designed to deliver deep bass with room for enclosure tuning in both sealed and ported configurations.
• RMS Range: 300w-1000w (500w RMS ideal) — Indicates the continuous power range the driver handles; pairing within this window supports clean, linear output without overdriving the voice coil.
• Peak Power: 1600w — Represents transient power handling for dynamic bass bursts when the system demands rapid energy delivery.
• Cone: Textured Non-Pressed Pulp with Resin — Provides stiffness and damping to reduce cone flex and improve control under high excursion.
• Voice Coil: 2.5" Dual 4 Ohm — Two 2.5-inch coils at 4 ohms each offer flexible wiring options for impedance matching and power distribution.
• Surround: Custom High Roll Foam with MASSIVE Logo — Supports linear excursion and durable sealing against air blowout at high output.
• Magnet: 120oz, double-stacked high-flux Y30 Strontium ferrite magnets — High magnetic flux and increased excursion potential aid low-end extension and control in demanding builds.
• Terminals: Terminal Case with Flexible Pure Copper Wire — Ensures low-resistance connections and reliable wiring for high-current signals.
• Basket: Heavy Gauge Steel — Robust frame that resists flex and maintains alignment under power.
• Tinsel Leads: High-Grade Woven Round — High-quality leads designed to withstand repeated motion during bass cycles without fatigue.
• X-Max: 15 mm — Specifies mechanical excursion capability, contributing to deeper bass response in suitable enclosures.
• SPL: 84.5 dB — Sensitivity indicator of how efficiently the driver converts electrical power into sound pressure at a standard distance.
• Fs: 36 Hz — Low-frequency resonance point, indicating potential for strong output in the bass region down around 36 Hz.
• Enclosure Options: Ported Box 13.8"H x 20"D x 13.8"W; Sealed Box 1 ft3 — These enclosure specs define the two supported volumes/ configs for integrating the sub into a car audio system.

The GTR 12" is built for car audio enthusiasts aiming for serious bass with solid build quality and flexible wiring options. Its combination of a heavy steel basket, large 120 oz magnet, and dual 4-ohm coils supports powerful, controlled output in either sealed or ported applications, with clear enclosure guidance to maximize performance in real-world installs.
