Dual-Chamber Design for Balanced, Precision Bass

This enclosure features two separate internal chambers, ensuring each subwoofer delivers consistent, balanced low-end. With 0.49?ft³ of air space per chamber, it maintains clean, accurate bass performance, giving your system tight, distortion-free sound across the entire frequency range.

Under-Seat Bass with Upward-Firing Power

Designed to fit neatly under the rear seat, this low-profile enclosure preserves full cargo space while delivering big bass. Its upward-firing layout projects powerful low frequencies throughout the cabin for an immersive audio experience. Constructed from 5/8" high-quality MDF, it minimizes resonance for cleaner, more accurate sound.
