What's Inside?
High-Excursion, High-Power Subwoofer with Rugged Cooling Design

Unleash powerful, distortion-free bass with a 2.5″ high-temperature voice coil built to handle extreme power levels. The compressed paper cone with double-stitched, high-excursion foam surround delivers deep, accurate low-end with impressive durability and control. Paired with a die-cast aluminum vented basket, this subwoofer stays cool and reliable even during high-output, hard-hitting sessions.

Sealed & Ported Enclosure Ready with Rugged Protection

Ensure every beat hits hard with a proprietary full-round PVC gasket that delivers an airtight seal for clean, punchy bass. Enjoy reliable, secure wiring thanks to heavy-gauge spring terminals, while the protective magnet cover shields your sub’s core components. Whether you prefer a sealed enclosure (2.82 cu ft) for tight, accurate lows or a ported enclosure (2.96 cu ft) for deeper, thunderous bass — this subwoofer is ready to perform.
