Concrete Audio Ported Trunk Subwoofer Enclosure – 10″ Single Box

Upgrade your bass setup with the Concrete Audio Ported Trunk Subwoofer Enclosure, engineered to deliver deep, powerful low-frequency performance from a single 10″ subwoofer. Designed to be mounted in the trunk of your vehicle, this ported (bass-reflex) enclosure allows both the subwoofer and the port to fire toward the rear, producing stronger and more resonant bass compared to sealed designs.

Crafted from 3/4″ birch wood for robust acoustics and long-lasting durability, this box features oxygen-free copper wire screw-in terminal cups for secure electrical connections and poly fill for controlled internal resonance. The rugged build and tuned porting make it a great choice for car audio enthusiasts who want impactful, low-end sound without sacrificing space or reliability.
