Many in-stock orders ship within 1-2 business days, but timing varies by item. Custom, built-to-order, oversized, special-order and supplier-direct products may need extra processing time. Free shipping applies to qualifying orders over $99 in the contiguous US. Approved returns may be subject to a restocking fee.
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 M Series 18" is built to deliver deep, hard-hitting bass with the kind of value that keeps serious bassheads coming back. Its double-stacked ferrite motor is optimized through Finite Element Analysis (FEA) for efficient airflow and heat dissipation, so it stays composed through long, loud listening sessions.
A triple-layer foam high-excursion surround and rigid composite paper cone team up with a 10" quad-layer progressive Nomex spider pack and a 3" BASV high-temperature dual voice coil for accurate, high-output low end. Equally at home in a ported or bandpass enclosure, the M Series 18" is offered in Dual 1 Ohm and Dual 2 Ohm coil configurations and is backed by recone options and a 1-year manufacturer warranty.
