Trinity Audio Single H Series 18" Subwoofer & 5000.1v2 5,000 Watt Monoblock Amplifier

The Trinity H Series 18'' Subwoofer delivers 3,500 Watts RMS from a quad-stacked ferrite motor, engineered for bass enthusiasts who demand peak performance in high-power, long-duration builds and paired with the 5000.1v2 5,000 Watt Monoblock Amplifier.

• 3,500 Watts RMS: High-power handling designed for demanding bass applications without excessive distortion when paired with a compatible amplifier.
• Quad-stacked ferrite motor (33% more ferrite): Provides a stronger magnetic field for precise control at high excursion, improving cone control and reducing distortion under heavy bass demands.
• FEA-optimized motor and airflow: Finite Element Analysis-informed design and optimized airflow in the motor and basket enhance structural integrity and heat management during extended sessions.
• Triple-layer foam high-excursion surround: Durable, flexible surround that supports extended bass travel while maintaining linear motion and reliability.
• Rigid composite paper cone with carbon fiber dustcap: Combines stiffness and lightweight design to minimize cone flex and preserve clarity at high output.
• 10" quad-layer progressive spider pack: Improves linearity and voice-coil control across the excursion range, aiding consistent low-end performance.
• 4" BASV high-temperature dual voice coil: Handles high temperatures and sustained power, enabling reliable operation in powerful builds.
• Dual impedance options (H18 D1 / H18 D2): D1 Re 1.8 Ω with FS 28.5 Hz; D2 Re 3.6 Ω with FS 26.5 Hz; both share large Sd (188.7 in2) and similar X-max (32 mm), allowing flexible amplifier pairing.
• Enclosure versatility: Suitable for both ported and bandpass configurations, expanding installation options for different vehicle spaces and tuning goals.
• Physical dimensions: Outer Diameter 18.45 in; Cutout Diameter 16.77 in; Mounting Depth 12 in, enabling straightforward integration in larger enclosures.
• Quality and support: Comprehensive QC checks, recone options, and a 1-year manufacturer warranty provide long-term reliability and serviceability.

In a real car audio build, this subwoofer excels in large, high-power enclosures where deep, tight bass is needed without sacrificing clarity. The dual-impedance design provides integration flexibility with a range of amplifiers, while the robust motor and heat-management features mitigate thermal compression during extended demos or competition-style playback. The combination of a rigid cone, advanced spider pack, and a high-temperature voice coil delivers controlled bass repeatability, making it well-suited to daily listening with wall-shaking impact or competition-grade demonstrations. Recone options and a 1-year warranty round out the long-term value for serious bass rigs.
