Trinity B Series 18" Subwoofer 1,500 Watts RMS

The Trinity B Series 18" Subwoofer 1,500 Watts RMS is built for bass enthusiasts who demand deep, dynamic low-end with reliable cooling and enclosure versatility. This 18" driver pairs a robust cast basket and a dual 3" voice coil design to deliver high power with precise control across demanding enclosures.

• RMS Power Handling: 1,500 Watts RMS continuous power, providing ample headroom for demanding bass applications when paired with an appropriate amplifier and enclosure.
• Dual 3" High-Temperature Voice Coils: Two 3" voice coils handle heat more effectively and offer flexible wiring options to suit different impedances and amplifier configurations.
• Cast Basket & All-Black Finish: Sturdy, rigid frame with a durable, sleek aesthetic that complements high-performance audio builds.
• Double-Stacked Motor with FEA Cooling: A two-layer motor design enhanced with Finite Element Analysis cooling to sustain performance during prolonged, high-output playback.
• High-Excursion Design with 10" Spiders: Ten spiders contribute to greater cone movement for deeper, more authoritative bass output without sacrificing control.
• Enclosure Versatility: Optimized for ported, 4th-order, and 6th-order bandpass enclosures to maximize bass response and sound quality in a variety of builds.
• Sensitivity / SPL: 92.5 dB (D2) or 92.8 dB (D4) (in typical measurement conditions), indicating strong output relative to input power for a subwoofer of this size.
• Impedance Options (D2/D4): Dual 3" coils with Re of 1.9 Ω + 1.9 Ω (D2) or 3.2 Ω + 3.2 Ω (D4), affecting how you wire the sub for different amp loads and system designs.
• Fs / Mechanical Params: Fs 24.3 Hz (D2) or 24.5 Hz (D4); Mms 523.3 g (D2) / 467.2 g (D4); Cms 0.09 mm/N; Sd 786 in² per coil pair, reflecting strong low-frequency capability and cone area.
• Physical Dimensions: Outer diameter 18.5 in; Cutout diameter 16.73 in; Mounting depth 10.7 in; Motor diameter 7.8 in; Displacement 0.52 ft³.
• Coil & Wire: 3" x 50 mm coil dimensions; Black CCA braid; Ferrite Y35 magnet assembly; 8 AWG terminal gauge for sturdy wiring connections.
• Warranty & Recone Support: 1-year manufacturer warranty with recone kits available to support long-term performance and serviceability.
• Extreme-Output Note: There are reports of operation at over 174 dB in some scenarios with no damage, illustrating robust build integrity under extreme use.

Benefits: This sub is designed for serious bass builds that use ported, 4th-order, or 6th-order bandpass enclosures, delivering deep extension and controlled response with high thermal headroom. The dual-voice-coil configuration and multiple impedance options provide wiring flexibility for different amplifier loads, while the FEA-optimized cooling and double-stacked motor maintain performance during long, demanding sessions. Recone support and warranty add long-term value for enthusiast installations.
