Trinity Audio Dual H Series 18" Subwoofers & TAS-8000.1 8,000 Watt Monoblock Amplifier

The Trinity Audio Dual H Series 18" Subwoofers pair two 3,500-watt RMS drivers with the TAS-8000.1 monoblock amplifier to deliver high-output bass in competition and daily-driven systems.

• Quad-stacked ferrite motor: Provides over 33% more ferrite than the M series for stronger magnetic force and sustained output during extended play.
• 4" BASV high-temperature dual voice coil: Features over 40% additional winding height to handle continuous high-wattage power without overheating.
• 10" quad-layer progressive spider pack: Maintains linear control at high excursion levels for consistent performance in demanding enclosures.
• Triple-layer foam high-excursion surround: Allows 32 mm X-max while preserving durability and restoring quickly after large cone movements.
• Fs, Qts and Vas parameters: H18 D1 measures 28.5 Hz Fs, 0.54 Qts and 86.9 L Vas; H18 D2 measures 26.5 Hz Fs, 0.5 Qts and 90.2 L Vas, suiting both sealed and ported designs.
• Mounting dimensions: 18.45" outer diameter, 16.77" cutout and 12" mounting depth fit standard 18-inch enclosures.

Two H Series 18" drivers matched to the 8,000-watt amplifier produce clean, high-SPL bass in ported or bandpass boxes for users building competition-grade or high-output daily systems that require proven thermal and mechanical headroom.
