Description
The Trinity E Series 15'' Subwoofer is built to deliver deep, controlled bass for value-minded car audio setups, boasting 800W RMS and 2400W peak with a durable gunmetal stamped basket and a 3" high-temperature dual voice coil.
- RMS Power: 800W continuous handling gives solid, real-world bass output from a mainstream car audio amplifier without stressing the electrical system.
- Burst/Peak Power: 2,400W peak capacity handles dynamic bass transients and musical crescendos without clipping.
- Dual Voice Coils: 3" high-temperature dual voice coil configuration supports flexible wiring—available as Dual 2-ohm (E15 D2) or Dual 4-ohm (E15 D4)—to match common amplifiers and impedance needs.
- Two Voice-Coil Models: E15 D2 and E15 D4 variants provide distinct electrical parameters (Fs, Re, Qts, etc.) to suit different enclosures and tuning goals while sharing a 15" diameter and 0.29 ft3 displacement.
- Magnet/Motor Architecture: Double-stacked motor structure with a gunmetal stamped basket enhances magnetic control and durability under demanding use.
- Cooling & Stability: Finite Element Analysis (FEA)–assisted cooling and stability design helps maintain performance during extended playback.
- Enclosure Recommendations: Best paired with ported, 4th-order, or 6th-order bandpass enclosures to maximize deep bass extension and musical impact.
- Dimensions & Displacement: Outer diameter 15.35", Cutout diameter 13.98", Mounting depth 7.56", Displacement 0.29 ft3; suitable for installations with limited mounting depth.
- Performance Parameters: Sd 124.6 in², Vas ~70–77 L (depending on variant), Xmax 15mm, SPL ~90 dB, BL 17.5–23.3 (variant dependent); these values describe physical footprint and potential sensitivity in the car environment.
- Warranty & Maintenance: 1-year manufacturer warranty with recone kits available for ongoing maintenance and long-term reliability.
In real-world builds, this subwoofer suits daily drivers and bass enthusiasts seeking strong, extended bass without major upgrades to electrical systems. Its flexible impedance options, enclosure recommendations, and serviceability make it a versatile choice for value-focused installations that still demand performance.
