Tame Low-Frequency Coverage in Any Venue

Broadside Arc & Virtual Arrays

Calculate electronic delay tapers to turn a straight line of ground-stacked subwoofers into a virtual arc. Control horizontal dispersion angle across wide festival stages without moving heavy cabinets.

Cardioid & In-Line Gradient

Calculate physical rear spacing, polarity inversion, and delay settings for 180° rear cancellation. Keep stage noise quiet for acoustic instruments and sensitive vocal microphones.

End-Fire Array Optimization

Model multi-row end-fire arrays with physical distance offsets matched to progressive delay settings. Achieve maximal forward acoustic summation with deep rear rejection.

Spatial Aliasing & Upper Frequency Bounds

Instantly see the maximum physical cabinet center-to-center spacing ($d \le \lambda / 2$) allowed before destructive spatial aliasing lobes appear in your coverage pattern.
