This spreadsheet is the Swiss Army knife for subwoofer configurations. It helps you design, in real-time, cardioid configurations like end-fired and gradient. Physical (arc) and delayed (straight) horizontal arrays.

You can use up to 12 speakers with omnidirectional, cardioid, super-cardioid and figure-eight speaker patterns. Apply low- and high-pass filters. Look at arrival times both absolute and relative.

It displays frequency and phase responses for 7 microphones. Shows you SPL and polar plots. Lastly, nearly everything can be normalized in order to see relative differences.

As of version 1.4 the results can be exported into Meyer Sound MAPP XT for increased accuracy.
