Frequency controlled thumping

The first thing that we did with a new Infinity 12" subwoofer that was purchased (for home, and not lab use), was to hook it up to our frequency generator and put it through a few paces. The sub is rated at 28 to 150 Hz, and, apparently, the resonant frequency of our conference room is approximately 47 Hz. Check out the video of it in action, and see our blog post!
