The Trinity Audio Solutions H Series 8" packs serious output into a compact footprint, making it ideal for tight installs that still need to hit hard. Its dual-stacked ferrite motor carries over 50% more ferrite than the M Series counterpart and is FEA-optimized for cooling and stability.
A triple-layer foam high-excursion surround pairs with a rigid composite paper cone and carbon-fiber dustcap, while a 6.5" layered progressive Nomex spider pack and a 2.5" BASV high-temperature dual voice coil keep it composed under power. Built for ported or bandpass enclosures, it is available in Dual 2 Ohm and Dual 4 Ohm configurations with recone support and a 1-year manufacturer warranty.
