SUBWOOFER ARRAY SIMULATOR

Design end-fire and gradient subwoofer arrays with 2 or 3 subs. Visualize polar patterns, frequency response at multiple angles, and calculate optimal delays for cardioid directivity.

How to use
  1. Choose a configuration -- select end-fire or gradient array type, set the number of subwoofers, and adjust spacing between them.
  2. Tune the parameters -- use individual gain, delay, phase, and allpass filter controls per subwoofer. The simulator calculates optimal delays automatically for each array type.
  3. Analyze the results -- the polar plot shows directivity at the selected frequency, while the frequency response graph shows output at multiple angles simultaneously.

Cardioid subwoofer arrays reduce low-frequency energy behind the array, improving stage clarity and reducing feedback in live sound applications.
