High-Output Slot-Port Subwoofer Enclosure

Built to move serious air, this ported slot-vent enclosure delivers loud, deep bass with authority and clarity. Precision-tuned to 35 Hz, it produces chest-hitting lows with smooth extension—powerful without sounding boomy. The large 4.25 ft³ internal volume maximizes subwoofer efficiency, unlocking stronger output and deeper, more immersive low-end performance.

Forward-Firing Behind-Seat Subwoofer

Designed with a forward-firing configuration, this enclosure directs bass straight into the cabin for maximum impact from a behind-seat installation. Built from heavy-duty 3/4″ MDF, the rigid construction minimizes flex and vibration, delivering cleaner, more accurate low-end performance you can feel.
