Gradient Array Calculator
Frequency at which rear cancellation is centred
Choose gradient type
Gradient array with front and rear subs. Delay/invert the rear element for cardioid response.
Endfire Array Calculator
Number of subwoofers in the endfire row
Design frequency for calculating wavelength and delay
Distance between acoustic centres of adjacent elements
Endfire array: subwoofers in line. Delay each element progressively so their outputs align toward the front.
Gradient Pattern Designer
Frequency at which the desired pattern is centred
Distance between front and rear elements
Select the desired directional pattern
Two‑element gradient pattern: adjust delay and amplitude ratio to shape cardioid, hypercardioid or figure‑8 patterns.
Sub Array Calculator
Number of subwoofers in the broadside row
Distance between acoustic centres of adjacent elements
Positive angles steer the beam to one side
Used to compute approximate beamwidth
Select amplitude weighting across the array
Broadside array: equal‑spaced subwoofers steered by delays and shading.
