Most products are covered by the manufacturer's warranty against defects. Damage from over-powering or improper installation isn't covered — we'll help coordinate any valid claim.

The Trinity Audio Solutions H Series 15" is a high-output subwoofer engineered for bassheads who want competition-grade output that still plays clean every day. Its quad-stacked ferrite motor packs over 33% more ferrite than the M Series and is FEA-optimized for airflow and heat management under the heaviest loads.
A triple-layer foam high-excursion surround pairs with a rigid composite paper cone reinforced by a carbon-fiber dustcap, while a 10" quad-layer progressive spider pack and a 4" BASV high-temperature dual voice coil deliver serious excursion and control. Built for ported and bandpass boxes, it is offered in Dual 1 Ohm and Dual 2 Ohm configurations with recone support and a 1-year manufacturer warranty.
