Being that this is your first time purchasing a subwoofer, you will likely become obsessed, as we all have here, and purchase multiple subs in the near future. The WAF was an issue for me in the beginning, but she got over it eventually and currently I have 3 rather large boxes in the living room. For a room of your size, it is going to be a must to buy multiple subwoofers to effectively pressurize the area. Look into SVS for the cylinder subs, they take up much less floor space.
