Trinity Audio Dual M Series 18" Subwoofers & 5000.1v2 5,000 Watt Monoblock Amplifier

The Trinity M Series 18" Subwoofer is a high-excursion, 2,000 Watts RMS driver built for bass enthusiasts who demand deep, articulate low-end with reliable, long-term performance. Its 650-ounce double-stacked ferrite motor, FE A-optimized structure, and advanced heat-management deliver clean, powerful bass even at elevated output.

• Power handling: 2,000 Watts RMS remains capable of sustained high-output bass; paired with optimized airflow to maintain performance during long play sessions.
• 650 oz double-stacked ferrite motor: Creates a strong magnetic field for high linearity and low distortion at loud levels, improving control over cone motion.
• FEA-optimized structure: Finite Element Analysis-informed chassis and motor design for rigidity and reduced flex, translating to better bass definition and consistency.
• Triple-layer foam high-excursion surround: Durable, flexible edge treatment that supports large excursions while preserving cone return and bass accuracy.
• Rigid composite paper cone: Provides stiffness and damping for precise bass rendering across the frequency spectrum with minimal cone flex.
• 10" quad-layer progressive Nomex spider pack: Robust support for voice-coil alignment under heavy excursion, aiding stability and linearity.
• 3" BASV high-temperature dual voice coil: Two large-diameter coils with high thermal tolerance to sustain power handling and reduce coil compression under heat.
• Enclosure compatibility: Designed to perform well in either ported or bandpass enclosures, offering flexibility for various install goals.
• Physical footprint: Outer Diameter 18.45 in; Cutout Diameter 16.77 in; Mounting Depth 11.22 in, helping plan installation in larger enclosures or custom builds.
• Displacement: 0.52 ft³ displacement per driver, informing enclosure volume decisions for tuning and bass extension.
• Two voice-coil configurations (D1 and D2): D1 uses Re 0.95 Ω per coil (two coils in parallel) with Qts ~0.436, Vas ~129.6 L, and BL ~19.4; D2 uses Re 1.9 Ω per coil with Qts ~0.40, Vas ~157.9 L, and BL ~31.1, offering tuning flexibility for different amps and boxes.

Extensively tested through FEA and real-world trials, recone options, and a 1-year manufacturer warranty accompany the subwoofer, providing confidence in both performance and long-term value for serious bass builds.
