Skip the enclosure-building step with a pre-built ported box tuned for 12-inch subwoofers. The 1.75 cubic foot internal volume tuned to 35 Hz is the sweet spot for most 12-inch drivers — this is where the BH-12S400 really comes alive.
MDF construction with black carpet wrap. The port is on the front face — no wall-bounce acoustics or clearance issues.
