Concrete Audio Ported Subwoofer Enclosure – 2×10″ Birch Wood Box

Take your bass performance to the next level with the Ported Subwoofer Enclosure, engineered to house two 10″ subwoofers and deliver deep, powerful low-frequency output with enhanced efficiency. This ported (bass-reflex) design uses tuned airflow to reinforce low bass response — giving you louder, richer bass than a sealed enclosure at similar power levels.

Built from 3/4″ birch wood with a rugged, pro-grade finish, this enclosure features oxygen-free copper wire screw-in terminal cups for secure electrical connections and poly fill to help control internal resonance and smooth the bass response. This enclosure is optimized for Concrete Audio C1 and C0 series subwoofers and similar 10″ drivers, making it ideal for car, truck, or custom audio system builds that demand impactful low end.
