This is quote an ingeniously design subwoofer. Its not just a 12″ (roughly) cube shaped passive sub with a 10″ aluminum woofer inside but rather a 12″ cube sub that is designed to be hidden away. If you see the attached pics (some pics are lifted off, you will know what we mean. The sub has a flared out port which you would connect a 28″ flex port to and then connect a ToeKick on the other end of the flex port. The sub can be hidden under the floor, behind walls or inside a cabinet and the only thing that you would see or hear is where the ToeKick is placed (again see our pics). The LF sound that is created by the 10″ woofer would travel out the flared port, through the flex port and exits out from the ToeKick. To the unknowing, the ToeKick looks like just any other heat or cool air vent but its actually the “outlet” where the bass signals will be emitted out from. This set was a former display piece and was never installed. The set will be shipped in two boxes, so factor x2 on the shipping. Local pickup from the store can be arranged.
