Unlike my previous post about the L-Acoustics preset guide, d&b guide’s its users to perform subwoofer alignment using their ArrayCalc simulation software. I have heard from more than one colleague that they stopped using their audio analyzer after they started using d&b ArrayCalc. With such claims of accuracy I was really looking forward to comparing the results from SubAligner.
Y7P + Y-SUB
At matched level with CUT engaged the center of the crossover region is at 138Hz.
Here’s a prediction at 125Hz.
The result from SubAligner is in good agreement. The minimum delay in ArrayCalc is 0.3ms. 1.35 + 0.3 = 1.7ms.
J12 + J-SUB
With the sub level offset +6dB from the low-mids and CUT engaged, the center of the crossover region is at 139Hz.
And now the results from SubAligner.
E8 + B6-SUB
At matched level with CUT engaged the center of the crossover region is at 144Hz.
And the SubAligner results.
Have you done any subwoofer alignment with ArrayCalc and then verified it in the field? What were your results?
