Subwoofer - ACI12 in a Sealed 3 Cu.Ft. Cabinet

The box was built to fit inside a cabinet in my living room. The now discontinued ACI Subwoofer is built ruggedly. This subwoofer really adds impact to any musical event. Live recordings have more scale with the sub on. Best thing was to hide this inside the cabinet. Painted black, it hides unnoticed. Bass effortlessly fills the room (which is about 25' x 14'). The doors are covered with white speaker grill cloth from Parts Express. The benefits of incorporating a sub were drastic. If I had the room I'd build two (left and right) but just one seems to do the trick nicely.
