This tool is a bare-bones theoretical simulator of how multiple subwoofers should sum in a given open area. It allows you to place different sources of audio on a 2D plane and adjust their settings, such as gain, phase flip, or delay; the plot will show you how the audio would propagate through the area and what the resulting amplitude at each point should be. If you hover over the plot, the tool will show you a readout of the predicted SPL, as well as a visualisation of the relative arrival times and gains at that point in space.
