The SPL Boxes SB112V is a heavy-duty single 12-inch vented subwoofer enclosure designed to maximize bass output while remaining compact enough for daily-driver installations. Built from durable 3/4-inch MDF with a tuned ported design, the SB112V is engineered for strong low-frequency extension, improved efficiency, and aggressive bass response compared to sealed enclosures.
