JL Audio TW1 12" Subwoofer 4 Ohm (PES112-TW1-4) – 010-03588-00 (93968)

JL Audio StowAway™ 12" Enclosed Subwoofer (PES112-TW1-4) is a compact, rugged subwoofer system engineered to deliver deep, controlled bass from a low-profile sealed enclosure that fits where traditional subwoofers cannot. Designed for marine, powersports, and versatile 12-volt applications, the StowAway uses a weather-resistant enclosure and a high-excursion 12TW1-4 shallow-mount driver to provide smooth, authoritative low-frequency performance in tight or exposed installations.

Rated for 300 W RMS and presenting a 4 Ω nominal load, the PES112-TW1-4 pairs easily with a wide range of quality mono amplifiers. Its downward-firing design and low-profile footprint allow secure mounting under seats, in lockers, or in confined spaces. Marine-grade materials and a protective mesh grille ensure durability in demanding environments.
