Description
The Trinity Audio Dual B Series 18" Subwoofers paired with the LOGIQ-3K 3,000 Watt Monoblock Amplifier is a high‑power bass solution built for serious enthusiasts who want deep, controlled low end with reliable cooling and enclosure versatility.
- RMS Power Handling: 1,500 Watts RMS per driver. This is the continuous power the subwoofer is designed to handle, enabling strong bass output without distortion when paired with an appropriate amplifier and enclosure.
- Dual 3" High-Temperature Voice Coils: 3" voice coils arranged for robust heat management, helping sustain power during extended bass bursts and high dynamic demands.
- Impedance Options: Re = 1.9 Ω + 1.9 Ω (D2) or 3.2 Ω + 3.2 Ω (D4). Dual coils allow flexible wiring to suit different amplifier loads and system goals.
- High-Excursion Design: 10" spiders and a double‑stacked motor with FEA cooling enable greater cone travel for deeper, more articulate bass under demanding conditions.
- Durable Mounting Assembly: Cast basket and an all‑black aesthetic combine rigidity with a sleek install and long‑term durability.
- Enclosure Versatility: Optimized for ported, 4th order, and 6th order bandpass enclosures to maximize bass response in various vehicle builds.
- Specifications at a Glance: Fs ~24.3–24.5 Hz; X-max 18 mm; Sd 786 in²; Vas ~188 L; SPL ~92.5–92.8 dB; BL ~21.6–25.5; Outer diameter 18.5", Cutout 16.73", Mounting depth 10.7".
- Coils, Winding, and Materials: Coil dimensions 3" × 50 mm; Wire gauge 8ga; Black CCA conductors; Ferrite Y35 magnets; Displacement ~0.52 ft³ per driver.
- Recone Kits & Warranty: Recone kits available and a 1-year manufacturer warranty on the subwoofer family for long-term support.
- LOGIQ-3K 3,000 Watt Monoblock Amplifier: Full‑bridge monoblock delivering 3,000 watts at a 2 Ω load and the same 3,000 watts at a 1 Ω load, thanks to Trinity’s Logiq Technology for consistent performance across impedance options.
Benefits: In a capable ported, 4th or 6th order system, these 18" drivers deliver deep, controlled bass with high excursion and reliable cooling, while the LOGIQ-3K maintains consistent output across common low-impedance loads. The combination suits high-SPL plays, demanding daily listening, and long sessions without overheating, with recone support and a warranty backing long-term reliability.
